Description

Technical Field

[0001] This disclosure relates to the field of data processing technology, and more specifically, to a method and system for determining the inundation treatment range of a pumped storage power station reservoir. Background Technology

[0002] During the construction of pumped storage power stations, the engineering layout, land use determination, and land acquisition analysis all require the impact range after the reservoir is impounded as the basis. This impact range is typically represented in engineering as the reservoir inundation treatment area, that is, the spatial area that the reservoir may affect under impoundment conditions.

[0003] Existing technologies typically determine reservoir inundation boundaries manually, based on engineering drawings, topographic data, and design water level data. Because this manual interpretation process heavily relies on the experience of the operators and is difficult to adapt to the varying reservoir formation conditions of different pumped-storage power station reservoirs, it can easily lead to insufficient accuracy and applicability in determining the inundation treatment area. Summary of the Invention

[0004] The purpose of this disclosure is to provide a method, system, electronic device, and computer-readable storage medium for determining the inundation treatment range of a pumped storage power station reservoir. This method can standardize the basic analysis data extracted from CAD engineering data and combine it with reservoir type, inundation impact judgment conditions, and boundary correction data to determine the target inundation treatment range and its zoning results, thereby improving the accuracy and applicability of determining the reservoir inundation treatment range in various reservoir scenarios.

[0005] Other features and advantages of this disclosure will become apparent from the following detailed description, or may be learned in part from practice of this disclosure.

[0006] According to a first aspect of the present disclosure, a method for determining the inundation treatment range of a pumped storage power station reservoir is provided, comprising: acquiring basic analysis data corresponding to the target reservoir based on CAD engineering data corresponding to the target reservoir in the pumped storage power station, and standardizing the basic analysis data to obtain standardized analysis data; wherein the basic analysis data includes topographic data, water level control data, engineering layout data, and surrounding landform data; determining the reservoir type corresponding to the target reservoir based on the standardized analysis data; determining the inundation impact judgment conditions corresponding to the target reservoir based on the reservoir type, and determining the initial inundation boundary corresponding to the target reservoir using the inundation impact judgment conditions and the standardized analysis data; performing boundary correction processing on the initial inundation boundary based on the boundary correction data corresponding to the reservoir type to obtain the target inundation boundary; wherein the boundary correction data represents the influence of engineering layout conditions and spatial connectivity on the inundation boundary under different reservoir types; determining the target inundation treatment range corresponding to the target reservoir based on the target inundation boundary, and performing partitioning processing on the target inundation treatment range to obtain inundation treatment partitioning results.

[0007] According to a second aspect of the present disclosure, a system for determining the inundation treatment range of a pumped storage power station reservoir is provided. The system includes: a data standardization module, used to acquire basic analysis data corresponding to the target reservoir based on CAD engineering data corresponding to the target reservoir in the pumped storage power station, and to standardize the basic analysis data to obtain standardized analysis data; wherein the basic analysis data includes topographic data, water level control data, engineering layout data, and surrounding landform data; a type determination module, used to determine the reservoir formation type corresponding to the target reservoir based on the standardized analysis data; and a boundary determination module, used to determine the boundary based on the reservoir formation type. The system describes the inundation impact determination conditions corresponding to the target reservoir, and uses the inundation impact determination conditions and the standardized analysis data to determine the initial inundation boundary corresponding to the target reservoir; a boundary correction module is used to perform boundary correction processing on the initial inundation boundary based on the boundary correction data corresponding to the reservoir type to obtain the target inundation boundary; wherein, the boundary correction data represents the influence of engineering layout conditions and spatial connectivity on the inundation boundary under different reservoir types; a range partitioning module is used to determine the target inundation treatment range corresponding to the target reservoir based on the target inundation boundary, and perform partitioning processing on the target inundation treatment range to obtain the inundation treatment partitioning result.

[0008] According to a third aspect of the present disclosure, an electronic device is provided, comprising: a processor; and a memory storing computer-readable instructions, which, when executed by the processor, implement the method for determining the inundation treatment range of a pumped-storage power station reservoir as described in the first aspect.

[0009] According to a fourth aspect of the present disclosure, a computer-readable storage medium is provided having a computer program stored thereon, which, when executed by a processor, implements the method for determining the inundation treatment range of a pumped storage power station reservoir as described in the first aspect.

[0010] The technical solutions provided in this disclosure may have the following beneficial effects: According to the method for determining the inundation treatment range of a pumped-storage power station reservoir in this example embodiment, on the one hand, by obtaining basic analysis data based on the CAD engineering data corresponding to the target reservoir in the pumped-storage power station and standardizing the basic analysis data, topographic data, water level control data, engineering layout data, and surrounding feature data can form a unified data foundation for analysis. This reduces judgment bias caused by manual interpretation and improves the reliability of the basic data in the inundation treatment range determination process. On the other hand, by determining the reservoir formation type corresponding to the target reservoir based on the standardized analysis data, it is possible to first clarify the reservoir formation scenario of the target reservoir before proceeding to the subsequent boundary determination process. This avoids processing different reservoir formation scenarios based on a single manual experience, ensuring that the inundation treatment range determination process matches the actual reservoir formation conditions of the target reservoir.

[0011] On the one hand, by determining the inundation impact criteria based on the reservoir type and using these criteria and standardized analysis data to determine the initial inundation boundary, boundary errors caused by differences in human experience can be avoided. On the other hand, by correcting the initial inundation boundary based on boundary correction data corresponding to the reservoir type, the impact of engineering layout conditions and spatial connectivity under different reservoir types on the inundation boundary can be further considered, making the target inundation boundary closer to the actual engineering impact range. Furthermore, by determining the target inundation treatment range based on the target inundation boundary and partitioning the target inundation treatment range, inundation treatment partitioning results can be generated simultaneously with the obtained inundation treatment range. Thus, the inundation treatment range results not only reflect the range boundary but also the treatment differences in different areas within the range, facilitating subsequent engineering decisions. Therefore, it has the advantage of improving the accuracy and applicability of determining the reservoir inundation treatment range in various reservoir types.

[0025] In the construction of pumped-storage power stations, the work of project layout, land use determination, and land acquisition analysis typically relies on the potential spatial impact range after reservoir impoundment. This spatial impact range is represented in the project as the reservoir inundation treatment area. The reservoir inundation treatment area not only represents the area that the water body may cover under impoundment conditions, but also includes relevant areas that require analysis due to water level rise, reservoir backwater, local connectivity, and changes in project construction conditions. The determination of this area affects the project construction land boundary and subsequent project decisions; therefore, it needs to be highly accurate and applicable to the project.

[0026] Relevant technologies typically determine reservoir inundation boundaries through manual interpretation based on engineering drawings, topographic data, and design water level data. This method relies heavily on the experience of operators, and inconsistencies in benchmarks, varying levels of precision, or unclear spatial correspondences between different data sources can lead to a lack of unified data foundation and judgment criteria for boundary determination. For pumped-storage power station reservoirs formed under different reservoir conditions, relying primarily on manual experience for judgment can easily result in discrepancies between the determined inundation treatment area and the actual engineering impact area, thus leading to insufficient accuracy and applicability of the determined inundation treatment area.

[0027] To address all or part of the technical problems in the aforementioned related technologies, this disclosure provides, in its exemplary embodiments, a method for determining the inundation treatment range of a pumped-storage power station reservoir. This method can be implemented by a system for determining the inundation treatment range of a pumped-storage power station reservoir. Figure 1 This illustration schematically shows a flowchart of a method for determining the inundation treatment range of a pumped-storage power station reservoir according to some embodiments of the present disclosure. (Reference) Figure 1 As shown, the method for determining the inundation treatment range of the pumped storage power station reservoir may include the following steps: Step S110: Based on the CAD engineering data corresponding to the target reservoir in the pumped storage power station, obtain the basic analysis data corresponding to the target reservoir, and standardize the basic analysis data to obtain standardized analysis data; wherein, the basic analysis data includes topographic data, water level control data, engineering layout data and surrounding landform data; Step S120: Based on standardized analysis data, determine the reservoir type corresponding to the target reservoir; Step S130: Based on the reservoir type, determine the inundation impact judgment conditions corresponding to the target reservoir, and use the inundation impact judgment conditions and standardized analysis data to determine the initial inundation boundary corresponding to the target reservoir. Step S140: Based on the boundary correction data corresponding to the reservoir type, perform boundary correction processing on the initial flood boundary to obtain the target flood boundary; wherein, the boundary correction data represents the influence of engineering layout conditions and spatial connectivity on the flood boundary under different reservoir types. Step S150: Based on the target inundation boundary, determine the target inundation treatment range corresponding to the target reservoir, and partition the target inundation treatment range to obtain the inundation treatment partitioning results.

[0028] According to the method for determining the inundation treatment range of a pumped-storage power station reservoir in this example embodiment, on the one hand, by obtaining basic analysis data based on the CAD engineering data corresponding to the target reservoir in the pumped-storage power station and standardizing the basic analysis data, topographic data, water level control data, engineering layout data, and surrounding feature data can form a unified data foundation for analysis. On the other hand, by determining the reservoir type corresponding to the target reservoir based on the standardized analysis data, it is possible to first clarify which reservoir scenario the target reservoir belongs to before proceeding to the subsequent boundary determination process. Furthermore, by determining the inundation impact judgment conditions based on the reservoir type and using the inundation impact judgment conditions and standardized analysis data to determine the initial inundation boundary, boundary errors caused by differences in human experience can be avoided. Moreover, by performing boundary correction processing on the initial inundation boundary based on the boundary correction data corresponding to the reservoir type, the influence of engineering layout conditions and spatial connectivity under different reservoir types on the inundation boundary can be further considered on the basis of the initial boundary, making the target inundation boundary closer to the actual engineering impact range. Furthermore, by determining the target inundation treatment range based on the target inundation boundary and performing zoning processing on the target inundation treatment range, inundation treatment zoning results can be generated simultaneously with obtaining the inundation treatment range. Therefore, the results of the inundation treatment scope determination not only reflect the boundaries of the scope but also the treatment differences between different areas within the scope, facilitating subsequent engineering decisions. This has the advantage of improving the accuracy and applicability of determining the reservoir inundation treatment scope in various reservoir construction scenarios.

[0029] The method for determining the inundation treatment range of the pumped storage power station reservoir in this example embodiment will be further explained below.

[0030] In step S110, based on the CAD engineering data corresponding to the target reservoir in the pumped storage power station, the basic analysis data corresponding to the target reservoir is obtained, and the basic analysis data is standardized to obtain standardized analysis data; wherein, the basic analysis data includes topographic data, water level control data, engineering layout data and surrounding landform data.

[0031] Pumped storage power stations can be defined as power station projects that achieve energy conversion through water regulation between upper and lower reservoirs. When analyzing the reservoir inundation treatment range of a pumped storage power station, the upper reservoir, lower reservoir, or other reservoirs requiring water storage impact analysis can be used as target reservoirs. CAD engineering data can represent engineering graphic data, engineering design results data, or engineering layout data generated in the form of computer-aided design, used to provide information such as the spatial location of the target reservoir and its surrounding area, the layout of engineering structures, and the distribution of land features. Basic analysis data can represent the original engineering data used to determine the reservoir inundation treatment range. Topographic data can represent data such as surface undulations, topographic boundaries, and elevation distribution in the area where the target reservoir is located. Water level control data can represent the design control water level, normal storage water level, or other control water level data related to the water storage analysis of the target reservoir. Engineering layout data can represent the layout data of the water-retaining structures, spillway structures, water supply facilities, and other engineering structures related to the target reservoir. Surrounding feature data can represent data on roads, settlements, farmland, forest land, waterways, or other features surrounding the target reservoir.

[0032] Specifically, layers, lines, regions, labels, and attribute information related to the target reservoir can be extracted from CAD engineering data. Based on the extraction results, topographic data, water level control data, engineering layout data, and surrounding feature data can be obtained. Since different types of data may originate from different layers or design documents, their coordinate datums, elevation datums, data formats, and spatial representations may differ. Therefore, the basic analysis data can be standardized to ensure that all types of data participate in subsequent processing under a unified data foundation, resulting in standardized analysis data.

[0033] In step S120, the reservoir type corresponding to the target reservoir is determined based on standardized analysis data.

[0034] The reservoir formation type refers to the method by which the target reservoir is formed during the engineering construction process. For example, the reservoir formation type can include at least one of the following: excavation and filling, river channel closure, and utilizing an existing reservoir. Excavation and filling can refer to a reservoir formation method that uses engineering measures such as excavation, filling, or enclosure to create a reservoir area. River channel closure can refer to a reservoir formation method that uses water blocking or interception of a river channel to create a backwater area. Utilizing an existing reservoir can refer to a reservoir formation method that uses an existing reservoir or reservoir area as a basis for reconstruction, expansion, or adjustment of operating conditions to form the target reservoir area.

[0035] Specifically, the formation method of a target reservoir can be identified based on the reservoir morphology, water-retaining conditions, river channel relationships, and the utilization status of existing reservoirs reflected in standardized analysis data. For example, when the target reservoir is mainly formed by artificial excavation, filling, or enclosure, it can be determined that the target reservoir has the characteristics of excavation and filling; when the target reservoir has a strong spatial relationship with the river channel and creates backwater effects through water-retaining conditions, it can be determined that the target reservoir has the characteristics of river channel closure; when the target reservoir has a corresponding relationship with the boundary of an existing reservoir area, the existing water level, or the scope of renovation or expansion, it can be determined that the target reservoir has the characteristics of utilizing an existing reservoir. Thus, the corresponding reservoir formation type can be obtained.

[0036] In step S130, based on the reservoir type, the inundation impact judgment conditions corresponding to the target reservoir are determined, and the initial inundation boundary corresponding to the target reservoir is determined using the inundation impact judgment conditions and standardized analysis data.

[0037] Among them, the inundation impact determination criteria can be used to determine whether the spatial area surrounding the target reservoir may be affected by water storage. The initial inundation boundary can be used to represent the boundary of the inundation treatment range initially obtained based on the reservoir type, inundation impact determination criteria, and standardized analysis data before the boundary correction treatment is completed.

[0038] Specifically, inundation impact assessment criteria can be selected based on the reservoir type. For reservoirs formed by excavation and filling, the criteria can be determined by considering the reservoir boundary and topographic elevation. For reservoirs formed by cutting off river channels, the criteria can be determined by considering the river direction, elevation changes, and connectivity. For reservoirs formed by utilizing existing reservoirs, the criteria can be determined by considering the existing reservoir boundary, operating water level, and the scope of renovation and expansion. Subsequently, the inundation impact assessment criteria can be applied to standardized analysis data to identify areas that meet the criteria, and based on this, the initial inundation boundary corresponding to the target reservoir can be extracted.

[0039] In step S140, based on the boundary correction data corresponding to the reservoir type, the initial flood boundary is corrected to obtain the target flood boundary; wherein, the boundary correction data represents the influence of engineering layout conditions and spatial connectivity on the flood boundary under different reservoir types.

[0040] The boundary correction data represents the data used to adjust the initial inundation boundary. Engineering layout conditions represent the arrangement, positional relationships, or control conditions of water-retaining structures, spillway structures, water replenishment facilities, and other engineering structures. Spatial connectivity indicates whether different spatial areas can transfer water level influence through rivers, ditches, reservoir channels, or other connecting paths. The target inundation boundary represents the boundary of the inundation treatment area obtained after correcting the initial inundation boundary. Specifically, the corresponding boundary correction data can be determined according to the reservoir type, and the initial inundation boundary can be adjusted using this data. For example, for excavation and filling reservoirs, the initial inundation boundary can be supplemented or deducted based on the reservoir's perimeter morphology, enclosure conditions, or local low-lying areas; for dammed river reservoirs, the initial inundation boundary can be corrected based on the river's backwater extension, the layout of spillway structures, and the layout of water replenishment facilities; for reservoirs utilizing existing reservoirs, the initial inundation boundary can be corrected based on the existing reservoir boundary, changes in operating water level, and the scope of renovation and expansion. Through the above processing, a target inundation boundary that better matches the actual engineering conditions of the target reservoir can be obtained.

[0041] In step S150, based on the target inundation boundary, the target inundation treatment range corresponding to the target reservoir is determined, and the target inundation treatment range is partitioned to obtain the inundation treatment partitioning result.

[0042] The target inundation treatment area can be defined as the spatial range that needs to be included in the inundation impact analysis of the target reservoir, determined based on the target inundation boundary. Zoning can refer to the spatial division of the target inundation treatment area according to regional location, impact source, land feature association attributes, or engineering treatment requirements. The inundation treatment zoning results can represent the zoning type and spatial range corresponding to different areas within the target inundation treatment area. Specifically, a corresponding areal range can be generated based on the target inundation boundary to obtain the target inundation treatment area corresponding to the target reservoir. After obtaining the target inundation treatment area, zoning can be performed by combining the locational differences of the internal areas within the target inundation treatment area and the association with surrounding land features to obtain the inundation treatment zoning results. Through the inundation treatment zoning results, the target inundation treatment area can not only reflect the final boundary but also the treatment differences of different areas within the area, thus facilitating subsequent engineering decision-making.

[0043] The contents of steps S110 to S150 will be described in detail below.

[0044] In some embodiments, the basic analysis data is standardized to obtain standardized analysis data, which specifically includes the following technical steps: The first step is to unify the coordinate reference of the topographic data, engineering layout data, and surrounding feature data to obtain spatial data under the same plane coordinate reference.

[0045] Coordinate datum unification processing refers to the process of converting data from different sources to the same plane coordinate system. A plane coordinate datum can represent a unified coordinate reference used to describe the planar position of spatial objects. Spatial data can represent data with a unified planar positional expression, used to characterize the spatial distribution of topography, engineering structures, and surrounding features under the same plane coordinate datum.

[0046] Specifically, since topographic data, engineering layout data, and surrounding feature data may originate from different CAD engineering files, different layers, or different surveying data, their coordinate origins, projection methods, or scale representations may differ. Therefore, based on a preset coordinate benchmark, coordinate transformation and position correction can be performed on spatial objects such as points, lines, and surfaces in the topographic data, engineering layout data, and surrounding feature data, ensuring that all types of spatial objects are under the same plane coordinate benchmark, thus obtaining spatial data. Through this processing, the locations of topographic boundaries, engineering structures, and surrounding features can maintain consistent planar positional relationships in subsequent analyses.

[0047] The second step is to unify the elevation benchmarks of the topographic data and water level control data to obtain topographic and water level data under the same elevation benchmark.

[0048] Among them, the unified elevation datum processing can refer to the process of converting elevation-related data to the same elevation reference datum. Topographic and water level data can represent topographic elevation data and water level control data formed under the same elevation datum, used to characterize the correspondence between topographic elevation and water level.

[0049] Specifically, since the elevation values ​​in topographic data and the water level values ​​in water level control data may use different elevation benchmarks or different elevation expression methods, elevation information such as surface elevation, reservoir bottom elevation, and slope elevation in the topographic data can be converted to the same benchmark based on a preset elevation benchmark. Similarly, design control water level, normal storage water level, or other control water level in the water level control data can be converted to the same benchmark to obtain topographic and water level data under the same elevation benchmark. This process avoids deviations in the comparison results between topography and water level due to inconsistent elevation benchmarks.

[0050] The third step is to spatially register spatial data under the same plane coordinate datum and topographic and water level data under the same elevation datum to obtain standardized analysis data.

[0051] Spatial registration refers to the process of associating data with planar location attributes with data with elevation or water level attributes according to their spatial location. Standardized analysis data refers to data formed after unifying planar coordinates, elevation benchmarks, and spatial correspondence, which provides a unified data foundation for subsequent reservoir type determination and inundation boundary determination. Specifically, based on the planar location of each spatial object in the spatial data, elevation values, water level values, or elevation-water level correspondences in the topographic and water level data can be matched to the corresponding spatial objects or spatial regions. For example, topographic elevation information can be associated with the corresponding topographic surface, reservoir area, or surrounding feature area, and design control water level and other water level information can be associated with the analysis range corresponding to the target reservoir.

[0052] For example, spatial registration can be performed through the following technical steps: based on spatial data, determine multiple spatial objects and the corresponding planar location range of each spatial object; based on the planar location range, determine candidate topographic water level data corresponding to each spatial object in the topographic water level data; determine the registration deviation between the candidate topographic water level data and the corresponding spatial object; if the registration deviation meets the preset deviation condition, determine the candidate topographic water level data as the target topographic water level data of the corresponding spatial object; associate the target topographic water level data with the corresponding spatial object to obtain a spatial object carrying topographic water level attributes; and generate standardized analysis data based on the spatial object carrying topographic water level attributes.

[0053] In this embodiment of the disclosure, the reservoir formation type can include excavation and filling, river channel closure, and utilization of existing reservoirs. Excavation and filling can refer to a reservoir formation method that creates a target reservoir basin through excavation, filling, enclosure, or a combination of these methods. River channel closure can refer to a reservoir formation method that uses water-retaining structures to intercept river flow, creating a water storage space in the upstream or adjacent areas of the river. Utilization of existing reservoirs can refer to a reservoir formation method that uses an existing reservoir or reservoir area as a basis for reconstruction, expansion, water level adjustment, or engineering layout adjustments to create the target reservoir's water storage space.

[0054] Specifically, refer to Figure 2 As shown, based on standardized analysis data, the reservoir formation type corresponding to the target reservoir is determined, specifically including the following technical steps: Step S210: Based on standardized analysis data, determine the basin formation information, main water-retaining information, river channel association information, and existing reservoir area utilization information corresponding to the target reservoir.

[0055] Specifically, the basin formation information represents information used to characterize the formation mode of the target reservoir basin. The main water-retaining structure information represents information used to characterize the water-retaining conditions of the target reservoir. The river channel association information represents information used to characterize the spatial relationship between the target reservoir and the river channel. The existing reservoir area utilization information represents information used to characterize whether the target reservoir utilizes existing reservoir area conditions. In essence, data objects related to the target reservoir basin, water-retaining structures, river channels, and existing reservoir areas can be extracted from standardized analysis data. Based on the spatial location, elevation attributes, and engineering attributes of each data object, basin formation information, main water-retaining structure information, river channel association information, and existing reservoir area utilization information are generated, respectively.

[0056] Step S220: Based on the reservoir basin formation information, determine the reservoir formation judgment result corresponding to the target reservoir.

[0057] The reservoir formation determination result can represent whether the target reservoir meets the characteristics of reservoir formation through excavation and filling. For example, the reservoir formation determination result can include whether it meets the criteria for reservoir formation through excavation and filling, whether it does not meet the criteria for reservoir formation through excavation and filling, or the degree of matching for reservoir formation through excavation and filling.

[0058] Specifically, based on the reservoir basin formation information, including the basin boundary, reservoir bottom elevation distribution, and surrounding topographic features, it can be determined whether the target reservoir was primarily formed by excavation, filling, or enclosure to create its water storage space. For example, if the basin boundary is relatively closed, the reservoir bottom elevation distribution and surrounding topography exhibit obvious engineering formation characteristics, or if the basin formation information includes excavation or filling areas, the target reservoir's formation determination result can be determined as conforming to the excavation-filling reservoir formation method. If the above characteristics are not met, the target reservoir's formation determination result can be determined as not conforming to the excavation-filling reservoir formation method.

[0059] Step S230: Based on the main water-blocking information and the river channel association information, determine the reservoir formation judgment result of the cut-off river channel corresponding to the target reservoir.

[0060] The result of determining whether a target reservoir meets the characteristics of a reservoir formed by cutting off a river channel can represent the determination of whether the target reservoir meets the characteristics of a reservoir formed by cutting off a river channel. For example, the result of determining whether a reservoir formed by cutting off a river channel can include whether it meets the criteria for a reservoir formed by cutting off a river channel, whether it does not meet the criteria for a reservoir formed by cutting off a river channel, or the degree of matching for a reservoir formed by cutting off a river channel.

[0061] Specifically, based on the location, control elevation, and enclosure range of the water-retaining structures in the main water-retaining information, as well as the spatial distribution of the river channel, the longitudinal elevation changes of the river channel, and the connectivity between the river channel and the reservoir area in the river channel association information, it can be determined whether the target reservoir will have a water-retaining impact on the relevant areas of the river channel through its water-retaining structures. For example, if the water-retaining structures correspond to the spatial location of the river channel, and the upstream or adjacent areas of the river channel can form a water storage area under the control elevation conditions, the result of the target reservoir's corresponding cut-off river channel reservoir formation determination can be determined as conforming to the cut-off river channel reservoir formation determination; if there is no effective correspondence between the main water-retaining conditions and the river channel, the result of the target reservoir's corresponding cut-off river channel reservoir formation determination can be determined as not conforming to the cut-off river channel reservoir formation determination.

[0062] Step S240: Based on the utilization information of the existing reservoir area, determine the reservoir formation judgment result corresponding to the target reservoir.

[0063] Among them, the judgment result of using existing reservoirs to form a reservoir can indicate whether the target reservoir meets the judgment result of using existing reservoirs to form a reservoir. For example, the judgment result of using existing reservoirs to form a reservoir can include whether it meets the criteria for using existing reservoirs to form a reservoir, whether it does not meet the criteria for using existing reservoirs to form a reservoir, or the degree of matching with the criteria for using existing reservoirs to form a reservoir.

[0064] Specifically, based on the existing reservoir area's boundary, operating water level, and expansion / reconstruction project layout information, it can be determined whether a target reservoir is formed on the basis of an existing reservoir or an existing reservoir area. For example, if the target reservoir's corresponding area overlaps with or is adjacent to the boundary of an existing reservoir area, and the expansion / reconstruction project layout has a spatial correspondence with the existing reservoir area, the determination result for the target reservoir's formation based on the existing reservoir can be determined as conforming to the criteria for formation based on the existing reservoir. If there is no effective utilization relationship between the target reservoir and the existing reservoir area, the determination result for the target reservoir's formation based on the existing reservoir can be determined as not conforming to the criteria for formation based on the existing reservoir.

[0065] Step S250: Based on the results of reservoir formation determination through excavation and filling, reservoir formation determination through river channel closure, and reservoir formation determination through utilization of existing reservoirs, determine the reservoir formation type corresponding to the target reservoir.

[0066] The reservoir formation type determination result can represent the reservoir formation mode of the target reservoir obtained based on multiple judgment results. Specifically, the reservoir formation mode that meets the judgment results can be determined as the reservoir formation type corresponding to the target reservoir. If only one judgment result meets the criteria, the reservoir formation mode corresponding to that judgment result can be determined as the reservoir formation type corresponding to the target reservoir; if multiple judgment results meet the criteria, the reservoir formation modes corresponding to multiple judgment results can be jointly determined as the reservoir formation type corresponding to the target reservoir. This allows for adaptation to situations where the target reservoir simultaneously possesses one or more reservoir formation characteristics.

[0067] In some embodiments, step S210, which involves determining the reservoir basin formation information, main water-retaining information, river channel association information, and existing reservoir area utilization information based on standardized analysis data, can be achieved through the following technical steps: Information on reservoir formation is obtained by extracting the reservoir basin boundary, reservoir bottom elevation distribution, and surrounding topographic features of the target reservoir from standardized analysis data. Specifically, the reservoir basin boundary represents the planar boundary of the target reservoir's water storage space. The reservoir bottom elevation distribution indicates the elevation changes at different locations along the bottom of the target reservoir. The surrounding topographic features reflect the reservoir basin's formation state, including topographic undulations, slope variations, and abrupt elevation changes near the boundary. In particular, the reservoir area graphic objects corresponding to the target reservoir can be identified from the standardized analysis data, and the reservoir basin boundary can be determined based on the closed lines, boundary lines, or area contours of these objects. The reservoir bottom elevation distribution can be extracted from the elevation attributes corresponding to the reservoir basin area in the standardized analysis data. Furthermore, the surrounding topographic features can be determined based on elevation changes on both sides of the reservoir basin boundary or within a predetermined range around the basin.

[0068] The location, control elevation, and enclosure range of water-retaining structures are extracted from standardized analysis data to obtain the main water-retaining information. The location of the water-retaining structure can represent the position of the dam, cofferdam, retaining wall, or other engineering structures used to create water-retaining conditions under a plane coordinate reference. The control elevation can represent the elevation data used when the water-retaining structure participates in water storage control or boundary determination. The enclosure range can represent the enclosed area formed by the water-retaining structure and its adjacent engineering structures. Specifically, engineering objects related to the water-retaining function can be identified based on the graphic objects, project name labels, or attribute fields of the engineering structures in the standardized analysis data; the location of the water-retaining structure is determined based on the point, line, and surface positions of the engineering objects; the control elevation is determined based on the corresponding elevation labels or attribute information of the engineering objects; and the enclosure range is determined based on the spatial relationship between the water-retaining structure and the reservoir boundary, and adjacent engineering structures.

[0069] River channel spatial distribution, longitudinal elevation changes, and connectivity between rivers and reservoir areas are extracted from standardized analysis data to obtain river channel association information. River channel spatial distribution represents the planar extension location and extent of the river within the target reservoir area. Longitudinal elevation changes represent the elevation variations along the river's extension direction. Connectivity between rivers and reservoir areas indicates whether a spatial connection exists between the river and the target reservoir area that can facilitate the transmission of water level influence. Specifically, linear, area, or labeled river objects can be identified from the standardized analysis data, and the river channel spatial distribution can be determined based on the identification results. Elevation attributes at multiple locations along the river's extension direction can be extracted, and the longitudinal elevation changes can be determined based on these attributes. Furthermore, based on the positional relationship between the river channel spatial distribution and the reservoir basin boundary, it can be determined whether the river intersects with, connects to, or is connected to the target reservoir area through low-lying channels, thus establishing the connectivity between the river and the reservoir area. Through these processes, river channel association information characterizing the association status between the target reservoir and the river can be obtained.

[0070] The utilization information of existing reservoir areas is obtained by extracting the boundaries, operating water levels, and layout scope of renovation and expansion projects from standardized analysis data. Specifically, the boundaries of existing reservoir areas represent the existing spatial boundaries of existing reservoirs or reservoir areas. The operating water levels represent the control water levels corresponding to existing reservoirs or reservoir areas under existing operating conditions. The layout scope of renovation and expansion projects represents the spatial scope of projects involved in the renovation, expansion, or adjustment of supporting projects for existing reservoir areas. In particular, the boundary objects corresponding to existing reservoirs or reservoir areas can be identified from the standardized analysis data, and the boundaries of existing reservoir areas can be determined based on these boundary objects. The operating water levels of existing reservoir areas can be extracted from water level markings, design specification attributes, or engineering attribute fields in the standardized analysis data. Furthermore, the layout scope of renovation and expansion projects can be determined based on the graphic objects and attribute information corresponding to the renovation, expansion, or supporting projects.

[0071] In some embodiments, the inundation impact determination criteria for the target reservoir are determined based on the reservoir type, specifically including the following technical steps: The first step, when the reservoir formation type includes excavation and filling, is to determine the first inundation impact judgment condition based on the design control water level in the water level control data and the reservoir basin boundary and reservoir bottom elevation distribution in the reservoir basin formation information; wherein, the first inundation impact judgment condition includes being located within the reservoir basin boundary and the reservoir bottom elevation not exceeding the design control water level.

[0072] The design control water level can refer to the design water level value used as the benchmark for water level determination in the analysis of the target reservoir inundation treatment area. It can be determined based on at least one of the target reservoir's normal storage water level, design flood level, check flood level, or engineering analysis conditions. It is used to compare with the reservoir bottom elevation, river channel elevation, or surface elevation to determine whether the corresponding spatial location may be affected by water storage. The first inundation impact determination condition can refer to the determination condition set for the excavation and filling reservoir construction scenario. It is used to determine whether the corresponding spatial location belongs to the potential inundation impact area under the excavation and filling reservoir construction scenario within the range defined by the reservoir basin boundary, based on the elevation relationship between the reservoir bottom elevation and the design control water level.

[0073] Specifically, when the target reservoir's formation type includes excavation and filling, the reservoir basin boundary can be determined first based on the basin formation information, and this boundary can be used as a planar constraint. Then, the reservoir bottom elevation at different spatial locations within the basin boundary can be determined based on the reservoir bottom elevation distribution. Finally, the reservoir bottom elevation at each spatial location can be compared with the design control water level. If a spatial location is within the basin boundary and its corresponding reservoir bottom elevation is not greater than the design control water level, then that spatial location meets the first inundation impact judgment condition. If a spatial location is outside the basin boundary, or its corresponding reservoir bottom elevation is greater than the design control water level, then that spatial location does not meet the first inundation impact judgment condition. Thus, the judgment process in the excavation and filling reservoir formation scenario is simultaneously constrained by both the basin's planar range and elevation conditions.

[0074] The second step, when the reservoir formation type includes the case of river channel closure, is to determine the second inundation impact judgment condition based on the design control water level in the water level control data, the control elevation in the main water-retaining information, the longitudinal elevation change of the river channel in the river channel association information, and the river channel connectivity relationship; among them, the second inundation impact judgment condition includes the river channel being connected to the reservoir area along the river channel direction and the river channel elevation not being greater than the design control water level.

[0075] Among them, the control elevation can represent the elevation value of the main water-retaining structure participating in the water-retaining condition judgment in the water storage analysis. It can be determined based on the dam crest elevation, water-retaining elevation, overflow control elevation, or control elevation in the design documents, and is used to determine whether the main water-retaining structure can form a water storage impact under the corresponding water level conditions. The river channel elevation can represent the riverbed elevation, riverbank control elevation, or river channel cross-section control elevation corresponding to different positions along the river's extension direction. The second inundation impact judgment condition can represent the judgment condition set for the scenario of a truncated river channel forming a reservoir. It is used to determine whether the relevant spatial location of the river channel belongs to the potential inundation impact area based on the connectivity between the river channel and the reservoir area and the relationship between the river channel elevation and the design control water level, considering the main water-retaining conditions.

[0076] Specifically, when the target reservoir's formation type includes river channel closure, the control elevation in the main water-retaining information can be used to determine whether the target reservoir possesses the water-retaining conditions necessary to form water storage or backwater effects. If the water-retaining conditions are met, the river channel elevation corresponding to different spatial locations along the river direction can be determined based on the longitudinal elevation changes in the river channel association information. Furthermore, the connectivity of each spatial location with the reservoir area can be determined based on the river channel connectivity. If a spatial location is connected to the reservoir area along the river direction, and the corresponding river channel elevation is not greater than the design control water level, then that spatial location meets the second inundation impact judgment condition. If a spatial location is not connected to the reservoir area, or the corresponding river channel elevation is greater than the design control water level, then that spatial location does not meet the second inundation impact judgment condition. Thus, the judgment process in the river channel closure reservoir formation scenario can be correlated with the water-retaining conditions, the river channel extension direction, and the backwater impact range.

[0077] The third step, when the reservoir formation type includes the use of existing reservoirs, is to determine the third inundation impact judgment conditions based on the existing reservoir area boundary, existing reservoir operating water level, and renovation and expansion project layout range in the existing reservoir area utilization information, as well as the design control water level in the water level control data. The third inundation impact judgment conditions include being located within the boundary of the existing reservoir area, or being located within the renovation and expansion project layout range and having a surface elevation not greater than the design control water level.

[0078] Among them, the existing reservoir operating water level can represent the water storage control water level adopted by the existing reservoir or the formed reservoir area under existing operating conditions, and can be used to reflect the existing water level base when the target reservoir utilizes the existing reservoir area. Surface elevation can represent the ground elevation value corresponding to the spatial location around the target reservoir, and can be determined based on elevation points, contour lines, digital elevation models, or cross-sectional elevation data in topographic data. The third inundation impact judgment condition can represent the judgment conditions set for the scenario of utilizing the existing reservoir to form a reservoir, used to combine the existing range of the existing reservoir area, the new design control water level, and the spatial range involved in the reconstruction and expansion project to determine whether the relevant spatial location belongs to the potential inundation impact area.

[0079] Specifically, when the target reservoir's formation type includes utilizing an existing reservoir, the boundary of the existing reservoir area can be used as the basis for determining the existing water storage impact range, and the layout range of the expansion and renovation project can be used as the basis for determining the newly added impact range. For spatial locations located within the boundary of the existing reservoir area, it can be determined that the spatial location meets the third inundation impact determination condition; for spatial locations located within the layout range of the expansion and renovation project, the corresponding surface elevation can be further determined and compared with the design control water level. If the surface elevation corresponding to the spatial location is not greater than the design control water level, it can be determined that the spatial location meets the third inundation impact determination condition; if the spatial location is not located within the boundary of the existing reservoir area and does not meet the layout range and elevation requirements of the expansion and renovation project, it can be determined that the spatial location does not meet the third inundation impact determination condition. Thus, the determination process in the scenario of utilizing an existing reservoir for reservoir formation can take into account both the existing reservoir area and the newly added impact range formed by the expansion and renovation project.

[0080] The fourth step is to determine the inundation impact determination conditions corresponding to the target reservoir based on at least one of the first, second, and third inundation impact determination conditions.

[0081] The inundation impact determination criteria for the target reservoir can be represented as a set of determination criteria selected and combined based on the reservoir formation type of the target reservoir. These criteria are used in subsequent processing to determine whether the spatial location of the target reservoir meets the requirements for inundation impact analysis. Specifically, based on the reservoir formation type of the target reservoir, at least one determination criterion matching the reservoir formation type can be selected from the first, second, and third inundation impact determination criteria as the inundation impact determination criteria for the target reservoir. If the target reservoir corresponds to only one reservoir formation type, the inundation impact determination criteria corresponding to that reservoir formation type can be used as the inundation impact determination criteria for the target reservoir. If the target reservoir corresponds to at least two reservoir formation types, the inundation impact determination criteria corresponding to each of the at least two reservoir formation types can be combined to obtain the inundation impact determination criteria for the target reservoir.

[0082] In some embodiments, reference Figure 3 As shown, the initial inundation boundary corresponding to the target reservoir is determined using inundation impact assessment criteria and standardized analysis data. The specific technical steps include the following: Step S310: Based on the spatial data in the standardized analysis data, determine the target analysis area corresponding to the target reservoir.

[0083] The target analysis area represents the spatial processing range surrounding the target reservoir used for assessing inundation impact. This area can be determined based on the reservoir's location, engineering design scope, distribution of surrounding features, and a preset outward extension distance, thus defining the spatial scope for subsequent inundation assessment. Specifically, the reservoir area, engineering structure distribution, and surrounding feature distribution can be extracted from spatial data. The target analysis area is then determined based on the reservoir area, combined with the engineering structure distribution and the preset analysis distance. This process avoids inundation assessments of areas unrelated to the target reservoir, reducing interference from invalid spatial objects in the subsequent boundary determination process.

[0084] Step S320: Based on the topographic and water level data in the standardized analysis data, determine the candidate inundation areas within the target analysis area that meet the inundation impact judgment conditions.

[0085] The candidate inundation area can be defined as a spatial region within the target analysis area that, based on topographic water level data and inundation impact assessment criteria, may be affected by the impoundment of the target reservoir. Since the candidate inundation area has not yet undergone spatial connectivity screening, it can include areas connected to the main reservoir area, or localized areas that only meet the elevation requirements but are not actually connected. Specifically, spatial locations or spatial units within the target analysis area can be mapped to topographic water level data to obtain the corresponding elevation values, water level values, or elevation-water level comparison results for each spatial location. Subsequently, the inundation impact assessment criteria corresponding to the target reservoir can be used to determine the spatial locations within the target analysis area. Spatial locations that meet the inundation impact assessment criteria are aggregated to obtain the candidate inundation area.

[0086] Step S330: Based on the spatial data in the standardized analysis data, determine the spatial connectivity between the candidate inundation area and the main reservoir area of ​​the target reservoir.

[0087] The main reservoir area can represent the primary reservoir area within the target reservoir used for water storage and serving as the starting area for inundation impact. Spatial connectivity status indicates whether there is a spatial continuity or water level impact transmission path between the candidate inundation area and the main reservoir area. For example, spatial connectivity status can include connectivity and disconnection. Specifically, based on the positional relationship between the candidate inundation area and the main reservoir area in the spatial data, it can be determined whether they intersect, connect, or are connected through spatial paths such as rivers, ditches, or low-lying channels. For candidate inundation areas with a continuous spatial relationship to the main reservoir area, their spatial connectivity status can be determined as connectivity; for candidate inundation areas that meet the elevation conditions but do not have an effective spatial connection with the main reservoir area, their spatial connectivity status can be determined as disconnection. This process avoids mistakenly including enclosed low-lying areas in the initial inundation boundary simply because the elevation conditions are met.

[0088] Step S340: The candidate flooded areas with a spatial connectivity status are determined as connected flooded areas.

[0089] The connected inundation region can be defined as a region within the candidate inundation region that is spatially connected to the main reservoir area. The connected inundation region can serve as the base region for extracting the initial inundation boundary. Specifically, based on the spatial connectivity obtained in step S330, candidate inundation regions can be filtered, retaining those with a connected spatial connectivity state and identifying them as connected inundation regions; candidate inundation regions without a connected spatial connectivity state can be excluded from the initial inundation boundary generation. This process ensures that the initial inundation boundary formation object maintains a real spatial connection with the target reservoir's main reservoir area.

[0090] Step S350: Extract the boundary of the connected inundation area, remove the non-connected area and smooth the boundary to obtain the initial inundation boundary corresponding to the target reservoir.

[0091] Boundary extraction refers to the process of extracting boundary lines from the outer edges of connected inundated areas. Disconnected area removal refers to the deletion of local areas formed during boundary extraction or region aggregation that do not meet the continuity requirement with the main reservoir area. Boundary smoothing refers to the correction of sharp corners, burrs, or local discontinuities in the boundary lines to improve the continuity of the boundary representation and engineering readability. The initial inundation boundary represents the preliminary boundary result obtained from the inundation impact judgment conditions and standardized analysis data before boundary correction. Specifically, connected inundated areas can first be spatially aggregated to form a continuous set of inundated areas; then, boundary lines can be extracted from the outer edges of the inundated area set to obtain the initial boundary lines. For disconnected local areas generated during region aggregation or boundary extraction, they can be removed based on their spatial continuity with the main reservoir area. Subsequently, the retained boundary lines can be smoothed to make the boundary lines more continuous in spatial representation.

[0092] In some embodiments, the initial flooding boundary is corrected based on the boundary correction data corresponding to the reservoir type to obtain the target flooding boundary. This includes the following technical steps: The first step, when the reservoir formation type includes excavation and filling, is to determine the first boundary correction data based on the reservoir basin perimeter topographic change features in the reservoir basin formation information and the enclosure range in the main water-retaining information.

[0093] The first boundary correction data can represent the data used to adjust the initial inundation boundary in a reservoir construction scenario. The topographic change features around the reservoir basin can reflect abrupt elevation changes, slope variations, low-lying extensions, or terrain closure near the basin edge. The enclosure area can reflect the planar restricted area formed by water-retaining structures or enclosure structures.

[0094] Specifically, when the target reservoir's formation type includes excavation and filling, the presence of continuous low-lying areas, slope transition areas, or enclosed areas formed by topographic uplift near the initial inundation boundary can be determined based on the topographic changes around the reservoir basin. The extent of these enclosed areas can then be used to determine whether they fall within the project's enclosed boundaries. If an area is within the enclosed boundaries, and the topographic changes around the reservoir basin indicate a continuous water storage influence between the area and the basin, then the data corresponding to that area can be used as supplementary data in the first boundary correction data. If an area meets the initial boundary judgment results but is located outside the enclosed boundaries or is obstructed by topographic uplift, then the data corresponding to that area can be used as deducted data in the first boundary correction data. This allows the boundary correction in excavation and filling reservoir formation scenarios to match the reservoir basin's edge topography and project enclosure conditions.

[0095] The second step, when the reservoir formation type includes reservoir formation by cutting off the river channel, is to determine the second boundary correction data based on the location and control elevation of the water-retaining structure in the main water-retaining information, the longitudinal elevation change of the river channel and the connectivity between the river channel and the reservoir area in the river channel association information, and the layout parameters of the spillway structure and the water supply facility in the engineering layout data.

[0096] The second boundary correction data can represent the data used to adjust the initial inundation boundary in the scenario of damming a river channel to form a reservoir. The spillway structure layout parameters can represent parameters such as the location, outlet direction, control elevation, energy dissipation area, or impact range of the spillway structure. The water replenishment facility layout parameters can represent parameters such as the location, diversion / discharge path, connection direction, or impact range of the water replenishment facility.

[0097] Specifically, when the target reservoir's formation type includes river channel closure, the spatial range affected by water-retaining conditions along the river can be determined based on the location and control elevation of the water-retaining structures; areas where backwater extension may occur along the river can be identified based on the longitudinal elevation changes of the river; and areas that can transmit water level influence with the reservoir can be screened based on the connectivity between the river and the reservoir area. Simultaneously, areas outside the main reservoir area that may be affected by discharge, replenishment, or diversion paths can be determined by combining the layout parameters of the spillway structures and the water replenishment facilities. If an area is connected to the reservoir area, and its elevation conditions, spillway structure layout, or water replenishment facility layout indicate that the area should be included in the inundation impact analysis, then the data corresponding to that area can be determined as supplementary data in the second boundary correction data; if an area is close to the river but lacks effective connectivity, or is not within the range affected by water-retaining conditions, then the data corresponding to that area can be determined as deducted data in the second boundary correction data. Thus, the boundary correction in the river channel closure reservoir scenario can simultaneously reflect the impacts of backwater extension, water-retaining control, and the layout of ancillary works.

[0098] The third step, when the reservoir type includes reservoirs built using existing reservoirs, is to determine the third boundary correction data based on the existing reservoir area boundary, existing reservoir operating water level, and the scope of renovation and expansion projects in the existing reservoir area utilization information.

[0099] The third boundary correction data represents the data used to adjust the initial inundation boundary in scenarios where existing reservoirs are utilized for reservoir construction. This data reflects the corrective effects of the existing reservoir area, new operating conditions, and the scope of expansion and renovation projects on the initial inundation boundary.

[0100] Specifically, when the target reservoir's formation type includes utilizing an existing reservoir, the boundary of the existing reservoir area can be used as a reference boundary for the existing inundation impact range. Based on the difference between the operating water level of the existing reservoir area and the design control water level of the target reservoir, it can be determined whether the existing reservoir area boundary needs to be maintained, expanded, or adjusted. For areas located within the scope of the renovation and expansion project, and which need to be included in the inundation impact analysis due to project renovation, expansion, or water level changes, the data corresponding to these areas can be designated as supplementary data in the third boundary correction data. For areas located near the boundary of an existing reservoir area but no longer meeting the current operating conditions or not belonging to the renovation and expansion impact range, the data corresponding to these areas can be designated as deducted data in the third boundary correction data.

[0101] The fourth step involves determining the area to be supplemented and / or the area to be deducted corresponding to the initial flooding boundary based on at least one of the first boundary correction data, the second boundary correction data, and the third boundary correction data.

[0102] The areas to be supplemented can represent areas outside the initial inundation boundary but need to be included in the inundation impact analysis based on the boundary correction data. The areas to be deducted can represent areas within the initial inundation boundary but are not suitable for further inclusion in the inundation impact analysis based on the boundary correction data. Specifically, at least one boundary correction data can be selected from the first, second, and third boundary correction data, depending on the reservoir type corresponding to the target reservoir. Subsequently, the boundary correction data can be spatially compared with the initial inundation boundary: areas located outside the initial inundation boundary and meeting the correction inclusion criteria can be identified as areas to be supplemented; areas located within the initial inundation boundary but meeting the correction exclusion criteria can be identified as areas to be deducted. When the target reservoir corresponds to multiple reservoir types, multiple boundary correction data can be combined to determine the areas to be supplemented or deducted, to avoid duplication or omission between different correction sources.

[0103] The fifth step involves performing boundary correction processing on the initial flooding boundary based on the area to be supplemented and / or the area to be deducted, to obtain the target flooding boundary.

[0104] Boundary correction processing can refer to the process of adjusting the initial inundation boundary based on the areas to be added and / or the areas to be deducted. The target inundation boundary can represent the boundary result used to determine the target inundation processing range after boundary correction processing. Specifically, when there are areas to be added, these areas can be merged into the area corresponding to the initial inundation boundary, and the boundary is updated based on the outer edge of the merged area; when there are areas to be deducted, these areas can be removed from the area corresponding to the initial inundation boundary, and the boundary is updated based on the outer edge of the removed area. When both areas to be added and areas to be deducted exist simultaneously, area merging and area removal processes can be performed separately, and the continuity of the processed boundaries can be adjusted to obtain the target inundation boundary.

[0105] In some embodiments, the target inundation treatment range corresponding to the target reservoir is determined based on the target inundation boundary, which can be done through the following technical steps: First, the target flood boundary is closed to obtain a closed flood boundary. Closure processing refers to connecting and organizing breakpoints, unconnected boundary segments, or endpoint gaps within the target flood boundary. A closed flood boundary represents a boundary result that is continuous from beginning to end and forms the outer edge of a planar region. Specifically, continuity detection can be performed on the target flood boundary to determine if any unclosed boundary segments exist. If unclosed boundary segments exist, they can be connected based on the endpoint positions, extension directions, and preset connection distances of adjacent boundary segments. If duplicate segments, intersecting segments, or abnormally short segments exist, they can be deleted, trimmed, or merged.

[0106] Then, inundation areas are generated based on closed inundation boundaries. An inundation area can represent a planar spatial region enclosed by a closed inundation boundary, characterizing the coverage area of ​​the target reservoir's water storage influence in planar space. Specifically, the closed inundation boundary can be used as the outer edge of the area, and surface construction processing is performed based on this outer edge to generate the corresponding inundation area. In the case of multiple closed boundaries, multiple inundation areas can be generated separately. Based on the inclusion, adjacency, or overlap relationships between the closed boundaries, these multiple inundation areas are merged, subtracted, or processed to form the inundation area corresponding to the target reservoir. Through the above processing, linear boundary results can be converted into planar results that can be used for area statistics and spatial overlay analysis.

[0107] Next, the inundated area is overlaid with surrounding feature data from the standardized analysis data to obtain the feature association attributes corresponding to the inundated area. Overlay processing involves analyzing the spatial intersection, inclusion, adjacency, or overlap of the inundated area and surrounding feature data under the same spatial reference. Feature association attributes represent the spatial and attribute relationships between the inundated area and surrounding features, such as feature type, feature area, overlap range, adjacent location, or association identifier at least one of these. Specifically, spatial overlay analysis can be performed on the inundated area and roads, settlements, cultivated land, forest land, water bodies, or other features in the surrounding feature data to determine the overlap, inclusion, or adjacency relationships between the inundated area and various feature objects. For feature objects spatially associated with the inundated area, their feature type, spatial range, and associated location can be extracted, and this information is used as the feature association attributes corresponding to the inundated area. Through this processing, the target inundation treatment area not only has a planar spatial boundary but also carries attribute information related to surrounding features.

[0108] Finally, based on the inundation area and the associated attributes of ground features, the target inundation treatment range corresponding to the target reservoir is determined. The target inundation treatment range can represent the final spatial range generated on the basis of the target inundation boundary for analyzing the inundation impact of the target reservoir. This target inundation treatment range can include the inundation area and the attribute information of ground features associated with the inundation area. Specifically, the inundation area can be defined as the main body of the spatial range corresponding to the target reservoir, and the associated attributes of ground features can be written into or associated with this main body of the spatial range to obtain the target inundation treatment range corresponding to the target reservoir. The target inundation treatment range can be expressed through at least one form: graphical boundary, isal region, attribute table, or spatial data file. Through the above processing, the target inundation treatment range can both express the spatial coverage result of the inundation impact and reflect its association with surrounding ground features, thus providing a data foundation for subsequent zoning processing.

[0109] Furthermore, the target flooding treatment area can be divided into zones to obtain a more intuitive flooding treatment result. Specifically, dividing the target flooding treatment area into zones to obtain flooding treatment zone results can be done through the following technical steps.

[0110] The first step is to divide the target flooding treatment area into multiple flooding analysis units.

[0111] In this context, an inundation analysis unit represents a spatial unit within the target inundation treatment area used for zoning determination. Inundation analysis units can be divided according to preset grids, feature boundaries, topographic boundaries, inundation area boundaries, or engineering analysis accuracy requirements. Specifically, the target inundation treatment area can be spatially divided into multiple inundation analysis units based on its isal region. Each inundation analysis unit can record its corresponding spatial location, area, boundary positional relationships, and feature association attributes. By dividing the target inundation treatment area into multiple inundation analysis units, the overall area can be transformed into a spatial object that can be determined unit by unit.

[0112] The second step is to determine the zoning type of each inundation analysis unit based on the positional relationship of each inundation analysis unit within the target inundation treatment area and the land feature association attributes corresponding to each inundation analysis unit; wherein, the zoning type includes at least one of the main inundation area, the secondary impact area, and the boundary transition area.

[0113] The location relationship refers to the position of the inundation analysis unit relative to the main area of ​​the target reservoir, the target inundation boundary, or the outer edge of the target inundation treatment area. The zoning type refers to the area category corresponding to the inundation analysis unit in the inundation treatment zoning results. The main inundation area refers to the area located within the target inundation treatment area and directly corresponding to the water storage impact of the main reservoir. The secondary impact area refers to the area included in the target inundation treatment area due to the influence of engineering structures, water supply facilities, discharge facilities, or local connectivity conditions. The boundary transition area refers to the area located near the edge of the target inundation treatment area, adjacent to the external area, and requiring focused verification in the engineering analysis. Specifically, the zoning type of each inundation analysis unit can be determined based on the distance between each inundation analysis unit and the outer edge of the target inundation treatment area, its location relationship with the main area of ​​the target reservoir, and the corresponding land feature association attributes. For example, an inundation analysis unit located within the target inundation treatment area and continuous with the main water storage area can be identified as the main inundation area; an inundation analysis unit related to the land features associated with the engineering structures or ancillary facilities can be identified as the ancillary influence area; an inundation analysis unit located near the edge of the target inundation treatment area or adjacent to land features outside the target inundation treatment area can be identified as the boundary transition area.

[0114] The third step is to merge flood analysis units with the same partition type and spatial continuity to obtain multiple flood treatment partitions.

[0115] Spatial continuity can represent the relationship between multiple inundation analysis units, such as boundary adjacency, surface adjacency, or spatial connection. Merging processing can represent the combination of multiple inundation analysis units of the same partition type and spatial continuity into a single partition surface. An inundation processing partition can represent a partitioned region formed by at least one inundation analysis unit. Specifically, multiple inundation analysis units can be classified according to their corresponding partition types; for multiple spatially continuous inundation analysis units under the same partition type, regions can be merged to form corresponding inundation processing partitions; for inundation analysis units of the same partition type but spatially discontinuous, different inundation processing partitions can be formed respectively. Through the above processing, scattered units in the partitioning results can be reduced, making the partitioning results more continuous in spatial representation.

[0116] The fourth step is to generate flooding processing partition results based on multiple flooding processing partitions and the partition types corresponding to each flooding processing partition.

[0117] The inundation treatment zoning result represents the spatial representation of each inundation treatment zone and its type within the target inundation treatment area. The inundation treatment zoning result can include at least one of the following: zone boundary, zone type, zone area, and corresponding land feature association attributes. Specifically, the corresponding zone type can be recorded for each inundation treatment zone, and the spatial extent, area, and land feature association attributes of each inundation treatment zone can be associated to generate the inundation treatment zoning result. This inundation treatment zoning result can be expressed through a zoning map, attribute table, or spatial data file. Through the above processing, the target inundation treatment area can be further transformed from a single-range result into a processed result with regional category information, thereby facilitating subsequent engineering decision-making.

[0118] Furthermore, in other embodiments of this disclosure, the target inundation treatment range and the results of inundation treatment zoning can be output and visualized. The visualization can represent a graphical representation of the spatial distribution of the target inundation treatment range and each inundation treatment zone. Preset formats can include at least one of vector files, attribute tables, zoning statistics tables, or analysis reports. Specifically, an inundation treatment range result map can be generated based on the target inundation treatment range, and a zoning result map can be generated based on the inundation treatment zoning results; the zoning type, zoning area, and land feature association attributes corresponding to each inundation treatment zone can also be written into the attribute table. Further, the target inundation boundary, target inundation treatment range, inundation treatment zoning results, and surrounding land feature data can be overlaid for display, facilitating result verification, range comparison, and engineering decision-making by engineers.

[0119] Furthermore, in the exemplary embodiments of this disclosure, a system for determining the inundation treatment range of a pumped storage power station reservoir is also provided. (Refer to...)
