[0002] Current water resource management systems are usually based on GIS technology, covering functions such as data collection, processing, analysis and report generation. These systems support dynamic monitoring and management of water resources at the macro level, and are mainly used in water resource master planning and regional hydrological analysis. For example, some systems can monitor the distribution and changes of water bodies, but do not conduct detailed analysis of specific reservoir water recipients and their diverse characteristics.

[0003] Traditional reservoir management has many limitations. For example, data collection relies on a single data source and lacks the ability to fuse multi-source data, making it difficult to fully reflect the actual situation of the reservoir's water-receiving objects. There is a lack of clear object classification methods, and the spatial characteristics of the reservoir's water-receiving objects (point, linear, and planar) are not clearly described, resulting in insufficient accuracy and practicality of the survey results. The visualization function is limited, and traditional systems are mostly presented in static charts or text data, which is difficult to meet the needs of modern management for dynamic and interactive displays.

[0004] Existing GIS technology is mainly used for wide-area analysis and macro-management, such as water resource distribution statistics and watershed analysis, and its functions are mostly concentrated on the visualization of hydrogeological data and the establishment of regional models. At the system application level, limited by modular design and functional expansion capabilities, the existing system is difficult to provide flexible functional configuration for specific scenarios (such as reservoir water receiving object surveys).

[0024] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the drawings of the specification. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary persons in the art without creative work should fall within the scope of protection of the present invention.

[0025] Example 1, reference Figure 1-Figure 4 , which is an embodiment of the present invention, provides a reservoir water receiving object survey method based on a geographic information system, comprising:

[0026] S1: Acquire reservoir data through the first data acquisition.

[0027] Furthermore, acquiring the reservoir data through the first data acquisition includes identifying data accuracy.

[0028] It should be noted that acquiring reservoir data through the first data collection includes collecting information about the reservoir and the corresponding water receiving objects.

[0029] The first data collection can be carried out by various methods, such as multi-source data integration or high-precision remote sensing image verification of reservoir location and data.

[0030] As a preferred embodiment, in this embodiment, the first data collection adopts multi-source data integration, and its principle steps are: by integrating the existing national water conservancy census data to establish a basic database of reservoir information. The national water conservancy census data covers reservoir information across the country, including basic information such as the name of the reservoir, geographical coordinates, district and county to which it belongs, capacity, and management unit. Using these data, preliminary geographical location information and basic attribute data are provided for each reservoir.

[0031] During the data integration process, the system will first import this basic information and automatically mark the type, size, distribution area, etc. of the reservoir. By matching the geographic coordinates of the reservoir, the system can provide geographic reference for the subsequent mapping and analysis of the water receiving objects. This process significantly speeds up data collection and avoids errors and omissions that may occur during manual entry.

[0032] At the same time, to ensure the integrity and accuracy of the data, the system also has real-time update and supplement functions. When preliminary data is missing or the information changes, the system can obtain the latest reservoir information from external data sources (such as data from local water conservancy departments or other relevant databases) through the network interface and automatically update the basic database. In this way, the system can maintain the timeliness of reservoir information and ensure the accuracy of each data query.

[0033] In another feasible embodiment, the first data acquisition uses high-precision remote sensing images to verify the location and data of the reservoir. The principle steps are: use high-precision remote sensing image data to verify the location and data integrity of the reservoir. Remote sensing technology uses satellite images and aerial images to obtain high-precision geographic information of the reservoir and its surrounding environment. These data usually have a high spatial resolution and can be accurate to a scale of several meters or even smaller, greatly improving the accuracy of geographic data.

[0034] During the data collection process, the system automatically obtains remote sensing images of the reservoir area, and combines the reservoir's geographic coordinates to automatically verify the reservoir's location, shape, and changes in the surrounding environment. By comparing with existing reservoir information, the system can detect possible errors in the data in real time, such as inaccurate reservoir location, missing data, outdated information, etc., and automatically correct or eliminate inaccurate parts.

[0035] In addition, the use of remote sensing images can also effectively identify changes in water areas around reservoirs, expansion of irrigation areas, and other situations, thereby providing a more detailed analysis perspective. This not only improves the efficiency of data integration, but also provides accurate basic data for subsequent surveys of reservoir water recipients. Through this high-precision data verification method, the system can achieve more reliable and accurate water resources management.

[0036] S2: Mark the water receiving object using the first marking method.

[0037] Furthermore, marking the water receiving object by the first marking method includes marking and distinguishing different areas.

[0038] It should be noted that the first labeling method can be a variety of methods, such as labeling water receiving objects according to the characteristics of points, lines, and surfaces, automatically generating and binding geographic coordinates and related reservoir information, or using a combination of colors and icons to indicate the status of water receiving objects, and intuitively presenting the status and category information of water receiving objects.

[0039] As a preferred embodiment, the first marking method in this embodiment adopts the characteristics of points, lines and surfaces to mark the water receiving objects, automatically generate and bind geographic coordinates and related reservoir information, and its principle steps are as follows:

[0040] Reference Figure 2 ,This water receiving object is usually marked with a single point on the map, such as water plants, pumping stations and other facilities. When drawing, the user only needs to click a location on the map, and the system will automatically generate the latitude and longitude data of the location, and bind it with the reservoir information to form a complete water receiving object.

[0041] Reference Figure 3, such as channels and water pipelines, are usually marked with a line on the map. When drawing, the user needs to click multiple points on the map in sequence, and the system will connect these points in the order of clicks to form a continuous line. The coordinates of each point will be saved and associated with the corresponding reservoir information to facilitate subsequent data query and management.

[0042] Reference Figure 4 , such as irrigation areas and water storage areas, are usually marked with polygons on the map. When drawing, the user clicks on multiple points on the map in sequence, and the system forms a closed area based on these points. The longitude and latitude information of all points in the area will be recorded and bound to the reservoir information for subsequent management and analysis.

[0043] In another feasible embodiment, the first labeling method uses a combination of colors and icons to indicate the status of the water receiving object, intuitively presenting the status and category information of the water receiving object, and the principle steps are as follows: for a water plant that is operating normally, a green icon can be used. For channels that are under maintenance, yellow or orange labels may be used. For damaged water source facilities, a red label can be used. The identification of each status not only uses different colors, but also can be combined with icons of different shapes, such as circular icons for water plants, line icons for channels, and polygonal icons for irrigation areas. These different identification methods can help users identify and distinguish different types of water receiving objects more quickly.

[0044] In addition, the system also supports dynamic adjustment of the display mode of annotations according to different needs. For example, when an emergency or important change occurs, the system can automatically adjust the display level of the map to give priority to the water receiving objects whose status has changed, so that users can track and handle them in time. This dynamic annotation management method not only improves the visualization of data, but also provides decision makers with real-time water resource management information.

[0045] It should be noted that marking the water receiving object by the first marking method also includes storing the marked geographic information in a database after the marking is completed. The system can automatically store the marked geographic information in a database according to the delineation type.

[0046] S3: Perform data analysis and visualize the results.

[0047] Furthermore, data analysis includes classification statistics based on different types of water receiving objects, automatic calculation of irrigation area, channel length and other indicators. Classification statistics are performed based on different types of water receiving objects, and indicators such as irrigation area and channel length are automatically calculated, and statistical tables of water receiving object distribution in different districts and counties are generated. During the data analysis process, the system can accurately calculate the area and path length based on GIS geographic information, and automatically update the data table of water receiving objects to ensure the accuracy of statistical analysis.

[0048] It should be noted that the visualization of the results includes real-time map display based on GIS technology. The system displays the integrated reservoir and water receiving object information on the map, and the distribution of water receiving objects in different areas can be viewed by switching the map level, and the display content can be automatically adjusted. Real-time map display based on GIS technology. The system displays the integrated reservoir and water receiving object information on the map, and the distribution of water receiving objects in different areas can be viewed by switching the map level. The system can automatically adjust the display content to give priority to key data or specially marked water receiving objects, and support intuitive display and query of detailed information, statistical data and historical records of water receiving objects.

[0049] Example 2, an embodiment of the present invention, provides a reservoir water receiving object survey method based on a geographic information system. In order to verify the beneficial effects of the present invention, scientific demonstration is carried out through economic benefit calculation and simulation experiments.

[0050] First, the experiment selected multiple reservoirs across the country as experimental objects, and used multi-source data integration methods to obtain information about reservoirs and their water receiving objects. The purpose of the experiment is to verify the advantages of combining multi-source data integration and GIS annotation methods in the data collection, annotation and visualization of reservoir water receiving objects, especially the innovative effects in improving data accuracy, reducing manual workload, and improving decision-making efficiency. The national water conservancy census data was used as the basic data source, covering basic information such as reservoir name, geographic coordinates, management unit, and capacity. The data is connected to the real-time database of the local water conservancy department through the system interface to ensure the timeliness and accuracy of the data. The national water conservancy census data is integrated through automated tools, and the system automatically matches and updates the relevant information of each reservoir according to the geographic coordinates, including the reservoir name, area, capacity, etc. This process does not require manual intervention, which greatly improves the efficiency of data processing. Furthermore, the location of the reservoir is verified by high-precision remote sensing images, and invalid or duplicate data is automatically eliminated.

[0053]

[0054] Measurement units: square kilometers for surface water-receiving objects and kilometers for linear water-receiving objects.

[0055] Longitude and latitude sequence: The drawn reservoir water receiving object, whether linear or planar, is composed of a series of point sequences. Each point represents the longitude and latitude of a geographical location, so the drawn trajectory of a reservoir water receiving object is composed of a longitude and latitude sequence.

[0056] By integrating multi-source data (such as national water conservancy census data and high-precision remote sensing images), the basic information of each reservoir can be quickly and accurately obtained, and the system can quickly match and update reservoir information based on geographic coordinates. This method eliminates the errors and omissions that may occur in the traditional manual input process, ensuring the real-time and accuracy of the data.

[0057] In traditional methods, the labeling of water-receiving objects often requires manual input of coordinate data, and errors are prone to occur. However, through the GIS system in this embodiment, the labeling of water-receiving objects is automatically generated and bound to the relevant reservoir information, reducing manual intervention and ensuring the accuracy of the labeling position and type. For example, the area of ​​the surface water-receiving object (such as the irrigation area) of Reservoir A is 25.4 square kilometers, and the length of the channel is 15.2 kilometers. The system can quickly generate these indicators through automated calculations, greatly improving the accuracy and efficiency of statistics.

[0058] Embodiment 3, an embodiment of the present invention provides a reservoir water receiving object survey system based on geographic information system, including a data acquisition module, a delineation module, and a data analysis module.
