Description

Technical Field

[0001] The invention relates to the technical field of fishway site selection, and in particular to a fishway site selection analysis system and method applicable to an existing water conservancy project. Background Art

[0002] With the construction of water conservancy projects, the ecological environment of natural water systems has been profoundly affected, especially hindering the migration and reproduction of fish. Existing water conservancy projects refer to water conservancy facilities that have been built and are in operation. Fishways refer to engineering facilities that help fish cross obstacles (such as dams) to ensure that fish can migrate freely in rivers.

[0003] The existing fishway site selection is carried out by analyzing the tidal level and hydraulic characteristics of the tidal river section to design the fishway entrance. However, it is only based on local hydrological characteristics or structural design, lacks a comprehensive assessment of the overall environment, and ignores ecological and geological diversity. There are problems such as inaccurate fishway site selection analysis and low adaptability of fishway site selection.

[0004] For example, the invention patent announcement number: CN106759164B discloses a method for designing a fishway entrance for a tidal river section and a fishway entrance, including: selecting a typical tidal process; calculating the tidal level; calculating the hydraulic characteristics of the fishway entrance section; designing the fishway entrance layout and water level; and determining various parameters of the fishway entrance. The present invention uses the tidal flow principle and the hydraulic characteristics of a tidal river section to establish a tide model for the tidal river section, calculates various tidal ranges and tidal level changes through the model, and then determines the optimal fishway entrance position for various tidal levels through the calculation of the hydraulic characteristics of the fishway entrance section.

[0005] For example, the invention patent publication number: CN105862687B discloses a baffle pipe-type fishway and design method, including: a pipe-type main body connecting the upstream and downstream of a water conservancy project, and baffles are evenly arranged along the pipe-type main body. The fishway pipe-type main body used in the invention is a pipe, that is, a pipe that can be buried underground or fixed in the air. It can even be arranged vertically.

[0006] However, in the process of implementing the technical solution of the invention in the embodiments of the present application, the present application found that the above technology has at least the following technical problems:

[0028] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] like Figure 1As shown, it is a structural schematic diagram of a fishway site selection analysis system applicable to an existing water conservancy project provided in an embodiment of the present application. The fishway site selection analysis system applicable to an existing water conservancy project provided in an embodiment of the present application includes: a fishway pre-site selection scheme collection module, which is used to collect fishway pre-site selection schemes of existing water conservancy projects transmitted by an application layer upload interface, wherein the fishway pre-site selection schemes include site selection information of each pre-built fishway and site selection information of the overall planning area; a site selection information preprocessing module, which is used to pre-process the site selection information of the overall planning area, and based on the site selection information of each pre-built fishway , analyze and obtain the site selection area parameters of each pre-built fishway; a site selection data acquisition module is used to arrange the inlet collection points and the outlet collection points of each pre-built fishway according to the site selection area parameters of each pre-built fishway, thereby collecting the site selection data of each pre-built fishway; a site selection data analysis module is used to determine the designated site selection location data of each pre-built fishway through analysis based on the site selection data of each pre-built fishway; an adaptive fishway site selection confirmation module is used to confirm the adaptive fishway site selection of the built water conservancy project based on the designated site selection location data of each pre-built fishway and after reprocessing.

[0030] In this embodiment, a site selection information preprocessing module, a site selection data collection module, and a site selection data analysis module are introduced, so that the fishway site selection is not limited to the adaptability to the terrain, but also comprehensively considers various geographical, environmental and engineering factors (such as surface vegetation density, annual average precipitation, historical water level, etc.) for scientific evaluation, and by establishing a geographical evaluation parameter system and a data analysis module, the site selection process can be based on a comprehensive evaluation and optimization of multiple factors to maximize the adaptability, environmental adaptability and fish passing effect of fishway construction. By modularizing the steps of fishway pre-site selection, site selection data analysis, and collection point layout, the entire site selection process is made more automated and intelligent. The method of determining the site selection center point and the connection path by means of image processing and other means improves the accuracy and automation level of data collection in the site selection area. Through the preset database, image processing technology and automatic collection point layout, the site selection process is made more intelligent, and the automatic collection and analysis of site selection data can save human resources and improve the accuracy and consistency of the evaluation.

Through modular site selection analysis, we can better integrate multiple factors such as environment, geology, construction, etc. to provide a more scientific and accurate fishway site selection plan, thereby achieving the technical effects of improving site adaptability, optimizing fish passage efficiency and reducing engineering risks.

[0031] Furthermore, the site selection information of each pre-constructed fishway specifically includes: the planned import site selection area area and the planned export site selection area area of ​​each pre-constructed fishway; the overall planning area site selection information includes: the length of the coastal coastline, the surface vegetation density, the ruggedness of the coastal coastline, the highest water level in the associated historical period, the lowest water level in the associated historical period and the average water flow velocity in the associated historical period.

[0032] In this embodiment, it should be noted that the reference association history period refers to a preset time period, for example, one month.

[0033] Furthermore, the site selection information of the overall planning area is preprocessed, specifically including: obtaining a preset site selection evaluation parameter benchmark data set in the database, and comparing it with the overall planning area site selection information to obtain an initial geographical evaluation index for the fishway site selection; the preset site selection evaluation parameter benchmark data set includes: reference coastal coastline length, reference surface vegetation density, reference coastal coastline ruggedness, reference maximum water level height, reference minimum water level height and reference average water flow velocity.

[0034] Furthermore, the initial geographical evaluation index for fishway site selection is obtained. The specific method is as follows:

[0035]

[0036] Where A represents the initial geographical assessment index for fishway site selection, S represents the length of the coastal coastline, ΔS represents the reference coastal coastline length, P represents the surface vegetation density, ΔP represents the reference surface vegetation density, e represents the natural constant, Q represents the ruggedness of the coastal coastline, ΔQ represents the reference coastal coastline ruggedness, H max Indicates the highest water level in the associated historical period, ΔH max Indicates the reference maximum water level, H min Indicates the lowest water level in the associated historical period, ΔH min represents the reference minimum water level, C represents the average water flow velocity in the associated historical period, ΔC represents the reference average water flow velocity, α 1 represents the influence weight of the length of the coastal shoreline, α 2 Represents the influence weight of surface vegetation density, α 3 represents the impact weight of the coastline ruggedness, α 4 Indicates the influence weight of the highest water level, α 5 Indicates the influence weight of the lowest water level, α 6 Indicates the influence weight of average water flow velocity.

[0037] In this embodiment, the initial geographical assessment index for fishway site selection is used to analyze the geographical conditions for fishway site selection, which can effectively reduce the difficulties and risks that may be encountered during the construction process, improve the effect and reliability of fishway operation, ensure the traffic efficiency and ecological sustainability of the fishway, and also provide a scientific basis for the formulation of subsequent specific construction plans.

[0038] It should be noted that the length of the coastline, surface vegetation density and the ruggedness of the coastline in the overall planning area site selection information can be obtained by querying the address survey platform, and the highest water level in the associated historical period, the lowest water level in the associated historical period and the average water flow rate in the associated historical period can be obtained by querying the water resources survey platform. The preset geographic assessment parameter benchmark data set of the overall planning area can be obtained from the database.

[0039] It should also be noted that the coastal shoreline length impact weight represents the numerical value of the impact of the coastal shoreline length on the initial geographical assessment index of the fishway site selection. When used, the impact weight corresponding to the coastal shoreline length can be directly obtained from the database. The corresponding relationship can be a pre-set mapping relationship. For example, the coastal shoreline length and the coastal shoreline length impact weight form a mapping set. The real-time coastal shoreline length is input into the mapping set to obtain the impact weight corresponding to the coastal shoreline length. The mapping relationship can be a one-to-one correspondence or a many-to-one relationship. The surface vegetation density impact weight represents the numerical value of the impact of the surface vegetation density on the initial geographical assessment index of the fishway site selection. When used, the impact weight corresponding to the surface vegetation density can be directly obtained from the database. The corresponding relationship can be a pre-set mapping relationship. For example, the surface vegetation density and the surface vegetation density impact weight form a mapping set. The real-time surface vegetation density is input into the mapping set to obtain the impact weight corresponding to the surface vegetation density. The mapping relationship can be a one-to-one correspondence or a many-to-one relationship. The impact weight of the coastal shoreline ruggedness indicates the numerical value of the impact of the coastal shoreline ruggedness on the initial geographical assessment index of the fishway site selection. When used, the impact weight corresponding to the coastal shoreline ruggedness can be directly obtained from the database. The corresponding relationship can be a pre-set mapping relationship. For example, the coastal shoreline ruggedness and the coastal shoreline ruggedness impact weight form a mapping set. The real-time coastal shoreline ruggedness is input into the mapping set to obtain the impact weight corresponding to the coastal shoreline ruggedness. The mapping relationship can be a one-to-one correspondence or a many-to-one relationship. The maximum water level height impact weight indicates the numerical value of the impact of the maximum water level on the initial geographical assessment index of the fishway site selection. When used, the impact weight corresponding to the maximum water level can be directly obtained from the database. The corresponding relationship can be a pre-set mapping relationship. For example, the maximum water level and the maximum water level height impact weight form a mapping set. The real-time maximum water level is input into the mapping set to obtain the impact weight corresponding to the maximum water level. The mapping relationship can be a one-to-one correspondence or a many-to-one relationship. The influence weight of the lowest water level represents the numerical value of the influence degree of the lowest water level on the initial geographical assessment index of the fishway site selection. When used, the influence weight corresponding to the lowest water level can be directly obtained from the database. The corresponding relationship can be a pre-set mapping relationship. For example, the mapping relationship is as follows: the lowest water level and the influence weight of the lowest water level form a mapping set. The real-time lowest water level is input into the mapping set to obtain the influence weight corresponding to the lowest water level. The mapping relationship can be a one-to-one correspondence or a many-to-one relationship.The average water flow velocity influence weight represents the numerical value of the influence degree of the average water flow velocity on the initial geographical assessment index of the fishway site selection. When used, the influence weight corresponding to the average water flow velocity can be directly obtained from the database, and the corresponding relationship can be a pre-set mapping relationship. For example, the mapping relationship is as follows: the average water flow velocity and the average water flow velocity influence weight form a mapping set, and the real-time average water flow velocity is input into the mapping set to obtain the influence weight corresponding to the average water flow velocity. The mapping relationship can be a one-to-one correspondence or a many-to-one relationship.

[0040] It should be understood that in this embodiment, the initial geographical assessment index for fishway site selection is obtained by processing the site selection information of the overall planning area, taking into account the mutual influence between these parameters. For example, longer coastlines are usually accompanied by more ecological habitats, which promote the growth of surface vegetation and increase the density of surface vegetation. The longer the length of the coastline, the more it often contains diverse terrain features, such as bends and bumps. The greater the ruggedness of the coastline, the more complex the water flow and the diversity of the habitat. The rugged coastline can provide more shelter to support the survival and reproduction of fish. The ruggedness of the coastline affects the flow pattern and speed of the water flow. The historical highest water level and the historical lowest water level jointly determine the fluctuation range of the water body. Higher water levels are usually accompanied by faster water flows. These parameters can reflect the ecological characteristics of the water area and affect the habitat and migration behavior of fish. Selecting these parameters can more accurately evaluate the ecological adaptability of the fishway and the construction feasibility of each pre-constructed fishway, ensuring that the final design can meet the needs of ecology, function and safety.

[0041] Furthermore, the analysis method of the site selection area parameters of each pre-constructed fishway includes: mapping and matching with the number of collection points corresponding to different ranges of initial geographical evaluation indicators for fishway site selection in each area interval of the planned import site selection area of ​​each pre-constructed fishway and the planned export site selection area of ​​each pre-constructed fishway, based on the area of ​​the planned import site selection area of ​​each pre-constructed fishway and the area of ​​the planned export site selection area of ​​each pre-constructed fishway, to obtain the number of collection points corresponding to the planned import site selection area of ​​each pre-constructed fishway and the number of collection points corresponding to the planned export site selection area of ​​each pre-constructed fishway, and marking them as the number of import collection points and the number of export collection points of each pre-constructed fishway, respectively, and combining them as the site selection area parameters of each pre-constructed fishway.

[0042] In this embodiment, the number of detection points is obtained by analyzing the area of ​​the planned inlet site selection area of ​​each pre-built fishway and the initial geographical evaluation index of the fishway site selection, so that the layout of the collection points is more scientific and reasonable, thereby achieving the maximum acquisition of effective data under limited resource conditions, ensuring the accuracy and reliability of the fishway site selection analysis. The pertinence of the detection point layout is improved, and unnecessary points are reduced, thereby reducing costs and manpower investment.

[0043] During the site selection process, the planned import and export area of ​​each pre-built fishway is first evaluated. The area of ​​the planned import site selection area and the planned export site selection area determines how many collection points are laid out in these areas to ensure the coverage of data collection and the representativeness of the data. The density and location of the sampling points can be reasonably planned, so as to more accurately evaluate the environmental characteristics of these areas. In addition, the number of collection points laid out in each area interval corresponding to the initial geographical evaluation index range of the fishway site selection in the preset area in the database is combined to perform two-level conditional screening to determine how many collection points need to be laid out in each specific area. This mapping matching makes the number of collection points laid out consistent with the area and complexity of the area, thereby ensuring the comprehensiveness and representativeness of the sampling and avoiding data deviation caused by too much or too little sampling. According to the results of the mapping matching, the number of collection points that need to be laid out in the planned import and planned export areas is obtained. The distribution density of these collection points is adjusted according to the changes in the area and complexity of the area. For example, larger areas or more complex terrains may require more collection points to fully capture the environmental characteristics of the area. Through the site selection area parameters, the location and number of data points that need to be collected in each fishway import and export area are clarified to ensure the comprehensiveness and representativeness of the data.

[0044] This process ensures the rationality and effectiveness of data collection by combining the planning area, initial geographical assessment indicators and the number of sampling points. This point distribution scheme optimizes the layout of sampling points by mapping and matching with the database, which facilitates better acquisition of the environmental characteristics of each area, thereby better determining whether the area is suitable for fishway construction, and providing a reliable data basis for subsequent fishway site selection confirmation.

[0045] Furthermore, the site selection data of each pre-constructed fishway is collected, specifically including: setting a monitoring period, and based on each inlet collection point and each outlet collection point of each pre-constructed fishway, thereby collecting first site selection data corresponding to each inlet collection point of each pre-constructed fishway within the monitoring period and second site selection data corresponding to each outlet collection point of each pre-constructed fishway; the first site selection data corresponding to each inlet collection point includes the maximum water level height, the daily average water level change range, the maximum water flow rate, the daily average water flow rate range, the average water temperature change rate, and the average pH value of the water body corresponding to each inlet collection point; the second site selection data corresponding to each outlet collection point includes the maximum water level height, the daily average water level change range, the maximum water flow rate, the daily average water flow rate range, the average water temperature change rate, and the average pH value of the water body corresponding to each outlet collection point; the first site selection data corresponding to each inlet collection point of each pre-constructed fishway within the monitoring period and the second site selection data corresponding to each outlet collection point of each pre-constructed fishway are jointly calibrated as the site selection data of each pre-constructed fishway.

[0046] In this embodiment, the maximum water level height corresponding to each inlet collection point can be obtained by measuring with a water level meter, the daily average water level change amplitude can be obtained by calculating the difference between the maximum water level height and the minimum water level height in a day, the maximum water flow rate can be obtained by measuring with a flow meter, and the daily average water flow rate range can be obtained by subtracting the maximum water flow rate and the minimum water flow rate in a day. The average water temperature change rate can be obtained by measuring the water temperature data with a thermometer, calculating the water temperature change between adjacent time points, and then calculating the average value. The average pH value of the water body can be obtained by measuring with a digital pH meter and then calculating the average value.

[0047] Further, the designated site selection location data of each pre-constructed fishway is determined, and the specific steps include: obtaining site selection reference data preset in the database, the site selection reference data including: reference water level height, reference water level change amplitude, reference water body flow velocity, reference water body flow velocity extreme difference, reference water temperature change rate, reference water body pH value; based on the site selection reference data and comparing one by one with the first site selection data corresponding to each inlet collection point of each pre-constructed fishway and the second site selection data corresponding to each outlet collection point of each pre-constructed fishway, the environmental assessment value of each inlet collection point of each pre-constructed fishway and the environmental assessment value of each outlet collection point of each pre-constructed fishway are obtained; based on the environmental assessment value of each inlet collection point of each pre-constructed fishway, the environmental assessment value of each pre-constructed fishway is obtained. The import collection point corresponding to the highest environmental assessment value is marked as the import adaptation site selection point of each pre-constructed fishway; based on the environmental assessment values ​​of each exit collection point of each pre-constructed fishway, the exit collection point of each pre-constructed fishway corresponding to the highest environmental assessment value is obtained, and marked as the exit adaptation site selection point of each pre-constructed fishway; the import adaptation site selection point of each pre-constructed fishway and the exit adaptation site selection point of each pre-constructed fishway are combined as the designated site selection location data of each pre-constructed fishway; the environmental assessment values ​​of each import collection point of each pre-constructed fishway are used to characterize the water environment quality of each import collection point of each pre-constructed fishway; the environmental assessment values ​​of each exit collection point of each pre-constructed fishway are used to characterize the water environment quality of each exit collection point of each pre-constructed fishway.

[0048] In this embodiment, the environmental assessment value is a quantitative expression of the environmental quality of the fishway construction area. By comparing the actual parameters of each collection point with the reference value, the environmental assessment value of each collection point of each pre-constructed fishway is calculated to characterize the quality of the environmental conditions of the collection point. The environmental assessment values ​​of each collection point of each pre-constructed fishway are sorted from large to small. The larger the assessment value, the more the environmental conditions in the area meet the needs of fishway construction. In this way, it is possible to intuitively determine which collection point is more suitable as the import or export position of the fishway, and select the import collection point and export collection point with the largest environmental assessment value as the adapted import and adapted export positions of the fishway, respectively. This selection process also ensures that the environmental conditions at the import and export are most conducive to fish migration and survival.

[0049] By comparing the site selection data of each pre-built fishway with the reference value, the most suitable fishway entrance and exit locations can be scientifically determined to maximize the passage efficiency and living conditions of fish, thereby improving the adaptability and construction success rate of the fishway and ensuring the long-term operation effect of the fishway.

[0053] It should be noted that the water level height impact weight represents the numerical value of the impact degree of the environmental assessment value of the collection point. When used, it can be directly obtained from the database to obtain the impact weight corresponding to the maximum water level height corresponding to each outlet collection point. The corresponding relationship can be a pre-set mapping relationship. For example, the maximum water level height corresponding to each outlet collection point and the water level height impact weight form a mapping set. The maximum water level height corresponding to the real-time collection point is input into the mapping set to obtain the water level height impact weight. The mapping relationship can be a one-to-one correspondence or a many-to-one relationship. The water level change amplitude impact weight represents the numerical value of the impact degree of the water level change amplitude on the environmental assessment value of the collection point. When used, the impact weight corresponding to the water level change amplitude can be directly obtained from the database. The corresponding relationship can be a pre-set mapping relationship.

[0054] It should be understood that in this embodiment, the environmental assessment values ​​of each inlet collection point of each pre-built fishway are obtained by processing the designated site location data of each pre-built fishway, taking into account the mutual influence between these parameters. For example, the maximum water level determines the potential fluctuation range of the water area, and the moderate daily average water level change range indicates the stability of the water body, which is very beneficial to the habitat and migration of fish. The relationship between the maximum water body flow rate and the daily average water body flow rate range shows that when the range is small, the water environment is more stable, which is conducive to the passage of fish; while excessive flow rate changes are not conducive to the smooth migration of fish. The water body flow rate affects the change of water temperature. Through the mixing effect of the water body, the stable flow rate and suitable temperature provide better conditions for the migration of fish. At the same time, suitable water temperature changes can maintain a stable pH value, thereby providing an environment suitable for fish survival. The daily average water level change range also affects the concentration of dissolved substances in the water body, thereby affecting the pH value of the water body. The moderate water level change range helps to maintain the ecological balance of the water body. These parameters jointly determine the environmental quality of the fishway through mutual influence, affecting the quality of the fishway site selection and the passage effect of fish.

[0055] Furthermore, based on the designated site selection location data of each pre-constructed fishway and after reprocessing, the adaptive fishway site selection of the existing water conservancy project is confirmed, and the specific steps include: based on the designated site selection location data of each pre-constructed fishway, collecting and obtaining the site selection influence data of each pre-constructed fishway; obtaining the site selection influence data reference value in the database, and processing it with the site selection influence data of each pre-constructed fishway to obtain the site selection comprehensive evaluation value of each pre-constructed fishway, selecting the pre-constructed fishway corresponding to the highest site selection comprehensive evaluation value, and using it as the adaptive fishway site selection for the existing water conservancy project; the site selection comprehensive evaluation value of each pre-constructed fishway is used to characterize the site selection feasibility of each pre-constructed fishway; the site selection influence data reference values ​​include: terrain height reference value, terrain extreme difference reference value, water body flow velocity reference value, water level height reference value, water body flow velocity extreme difference reference value and water level height extreme difference reference value.

[0056] In this embodiment, by collecting and comparing the site selection influencing data of each pre-built fishway, the safety assessment value of the site selection is calculated to ensure the scientificity and safety of the site selection for the fishway construction. Finally, by sorting the assessment values, the most suitable site is selected, thereby improving the success rate of the fishway construction and the long-term stability of operation, helping to reduce the risk of fishway construction and ensuring the efficient and sustainable operation of the project.

[0057] The method to obtain the comprehensive evaluation value of the site selection of each pre-built fishway is as follows:

The reference value of the site selection impact data can be obtained through the database.

[0061] It should also be noted that the influence weight can be obtained through the database. For example, the terrain height influence weight represents the influence degree of the terrain height of each sampling point corresponding to the construction baseline of each pre-constructed fishway on the comprehensive evaluation value of the site selection of each pre-constructed fishway. When used, the influence weight corresponding to the terrain height of each sampling point corresponding to the construction baseline of each pre-constructed fishway can be directly obtained from the database. The corresponding relationship can be a pre-set mapping relationship. For example, the terrain height of each sampling point corresponding to the construction baseline of each pre-constructed fishway and the terrain height influence weight form a mapping set. The real-time terrain height of each sampling point corresponding to the construction baseline of each pre-constructed fishway is input into the mapping set to obtain the terrain height influence weight. The mapping relationship can be a one-to-one correspondence or a many-to-one relationship. The terrain extreme difference influence weight indicates the influence degree of the terrain extreme difference corresponding to each sampling point of the construction baseline of each pre-built fishway on the comprehensive evaluation value of the site selection of each pre-built fishway. When used, the influence weight corresponding to the terrain extreme difference can be directly obtained from the database. The corresponding relationship can be a pre-set mapping relationship. For example, the mapping relationship is as follows: the terrain extreme difference and the terrain extreme difference influence weight form a mapping set, and the real-time terrain extreme difference is input into the mapping set to obtain the influence weight corresponding to the terrain extreme difference. The mapping relationship can be a one-to-one correspondence or a many-to-one relationship. The water flow velocity influence weight indicates the influence degree of the water flow velocity corresponding to each sampling point of the construction baseline of each pre-built fishway on the comprehensive evaluation value of the site selection of each pre-built fishway. When used, the influence weight corresponding to the water flow velocity can be directly obtained from the database. The corresponding relationship can be a pre-set mapping relationship. For example, the water flow velocity and the water flow velocity influence weight form a mapping set, and the real-time water flow velocity is input into the mapping set to obtain the influence weight corresponding to the water flow velocity. The mapping relationship can be a one-to-one correspondence or a many-to-one relationship. The water velocity extreme difference influence weight represents the influence degree of the water velocity extreme difference of each sampling point corresponding to the construction baseline of each pre-constructed fishway on the comprehensive evaluation value of the site selection of each pre-constructed fishway.

The maximum water level influence weight represents the influence degree of the maximum water level of each sampling point corresponding to the construction baseline of each pre-constructed fishway on the comprehensive evaluation value of the site selection of each pre-constructed fishway. When used, the influence weight corresponding to the maximum water level can be directly obtained from the database, and the corresponding relationship can be a pre-set mapping relationship. For example, the maximum water level and the maximum water level influence weight form a mapping set, and the real-time maximum water level is input into the mapping set to obtain the influence weight corresponding to the maximum water level, and the mapping relationship can be a one-to-one correspondence or a many-to-one relationship.The influence weight of the daily average water level height difference represents the influence degree of the daily average water level height difference of each sampling point corresponding to the construction baseline of each pre-constructed fishway on the comprehensive evaluation value of the site selection of each pre-constructed fishway. When used, the influence weight corresponding to the daily average water level height difference can be directly obtained from the database, and the corresponding relationship can be a pre-set mapping relationship.

[0062] It should be understood that in this embodiment, the comprehensive evaluation value of the site selection of each pre-built fishway is obtained by processing the site selection influence data of each pre-built fishway, taking into account the mutual influence between these parameters, for example: the terrain height affects the natural flow and accumulation of the water body, and the higher terrain causes greater fluctuations in the water level. Lower terrain will lead to higher water levels, affecting the suitability of the fishway. The extreme difference in terrain will directly affect the speed and direction of the water flow. Larger terrain extremes lead to large changes in the flow rate of the water body, thereby affecting the migration and habitat of fish. Higher water levels usually lead to faster water flows, which is crucial for fish to cross the dam and migrate. Too fast a flow rate will have a negative impact on fish, and moderate flow rates are conducive to fish passing through. The fluctuation (extreme difference) of the water flow rate affects the ecological environment of the water body, and the great change in flow rate may cause instability in the fish habitat. A stable flow rate helps to maintain the ecological balance of the fishway, and the fluctuation (extreme difference) of the water level can affect the flow rate of the water body. Larger water level fluctuations will cause unstable flow rate changes, thereby affecting the migration and survival of fish, and changes in terrain affect the range of changes in the water level. Higher terrain results in larger water level differences, while flatter terrain results in smaller water level changes, which helps the stability of the fishway.

[0063] Furthermore, the site selection influencing data of each pre-built fishway is collected and obtained. The specific method is as follows: a survey map of each pre-built fishway is obtained by a drone, and according to the designated site selection location data of each pre-built fishway, the designated site selection location data includes an inlet adaptation site selection point and an outlet adaptation site selection point; the inlet adaptation site selection point and the outlet adaptation site selection point of each pre-built fishway are located from the survey map, and a connecting straight line between the inlet adaptation site selection point and the outlet adaptation site selection point is constructed, and marked as a construction baseline; a number of sampling points are arranged on the construction baseline of each pre-built fishway, thereby counting the number of sampling points of each pre-built fishway from the survey map. The construction baseline of each pre-constructed fishway corresponds to the terrain height of each sampling point, and the terrain extreme difference corresponding to the construction baseline of each pre-constructed fishway is simultaneously counted from the survey map, and marked as the first influencing data of each pre-constructed fishway; a correction measurement period is set, and the maximum water flow rate, maximum water level, daily average water flow rate extreme difference and daily average water level extreme difference of the inlet adaptation site selection point and the outlet adaptation site selection point of each pre-constructed fishway in the correction measurement period are monitored and counted, and they are collectively marked as the second influencing data of each pre-constructed fishway; the first influencing data and the second influencing data are collectively marked as the site selection influencing data of each pre-constructed fishway.

[0064] In this embodiment, the survey map of each pre-built fishway is obtained by drone, and the inlet and outlet adaptation site selection points are accurately located, so as to ensure the accuracy of the site selection data, and then realize the scientific rationality of the fishway site selection; the sampling points of the construction baseline are arranged by using the terrain height and terrain extreme difference in the survey map, so as to obtain the terrain information of each site selection point, and then realize a detailed understanding of the terrain conditions for fishway construction, and ensure the controllability and safety of the construction process; set a correction measurement cycle, and count the dynamic parameters such as water flow velocity, water level height and flow velocity extreme difference of each site selection point, so as to realize the dynamic adjustment of the fishway design and site selection process, and improve the adaptability and long-term stability of fishway construction.

[0066] In this embodiment, the fishway pre-site selection plan is collected: the fishway pre-site selection plan of the built water conservancy project is transmitted through the application layer upload interface. The pre-site selection plan contains the site selection information of each pre-built fishway, which is used as the basic data for subsequent site selection analysis. Site selection information preprocessing: the collected site selection information of each pre-built fishway is sorted and preprocessed. After preprocessing, the site selection area parameters of each pre-built fishway are generated, and these parameters provide a data basis for subsequent sampling and analysis. Collect site selection data: according to the site selection area parameters obtained by preprocessing, collection points are arranged in the area of ​​each pre-built fishway, including import collection points and export collection points. Through these collection points, specific data of the fishway site selection area, such as environmental conditions, water flow characteristics, etc., are obtained to ensure the comprehensiveness and accuracy of the data. Determine the designated site selection location: use the collected site selection data for in-depth analysis to determine the optimal site selection point for each pre-built fishway, and these designated site selection location data are used to evaluate the feasibility and adaptability of each pre-built fishway. Determine the appropriate fishway site: Based on the specified site location data, reprocess the site selection plan to confirm the most suitable fishway site and ensure that the best construction location is selected in the existing water conservancy projects to achieve the best fish passage effect.

[0067] In summary, this embodiment performs preprocessing by combining the site selection information of the overall planning area and the site selection information of each pre-built fishway, thereby generating site selection area parameters for each pre-built fishway, and arranges collection points according to these parameters to obtain comprehensive site selection data, thereby achieving improved site selection adaptability, optimized fish passage efficiency and reduced engineering risks, and effectively solving the problems of inaccurate fishway site selection analysis and low fishway site selection adaptability in the prior art.
