[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0024] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0025] This application provides a method for river habitat data management, such as Figure 1 As shown, the river habitat data management method includes: Step 101: Divide the river habitat area to be marked into multiple topographic map units according to the latitude and longitude grid range of the area.
[0026] Step 102: Encode each topographic map unit according to the set latitude and longitude grid coding rules to obtain the topographic map code corresponding to each topographic map unit.
[0027] Step 103: Determine the river landform classification of each topographic map unit based on the river landform characteristics of each topographic map unit.
[0028] Step 104: Combine the topographic map code, the landform code corresponding to the river landform classification, and the important habitat identifier of each topographic map unit to obtain a combined code; the important habitat identifier is used to indicate whether the corresponding topographic map unit is a river landform with the preset important habitat function.
[0029] Step 105: Store the combined codes of each topographic map unit and the river geomorphic features in the geographic information system according to the geographic coordinates; the geographic information system is used to query the river geomorphic classification of the river geomorphic features of each river habitat.
[0030] This application addresses the problems of inconsistent spatial identification, insufficient correlation of river geomorphological features, and difficulties in data integration in existing river habitat labeling methods. By standardizing grid division and embedding coding of river geomorphological features, it ensures unified spatial data collection rules. Precise coding and labeling improve the scientificity and effectiveness of river spatial and shoreline management, and provides reliable data support for ecological protection and watershed management.
[0031] In one example implementation, the river habitat area to be labeled includes the river basin and the specific survey area. The river area to be labeled is determined based on remote sensing imagery (such as historical Google Earth imagery), covering both the river basin and the specific survey area.
[0032] In one example embodiment, step 101 specifically includes: selecting a topographic map of a first scale as the base map for the river habitat area to be labeled; the first scale is greater than or equal to 1:1,000,000. The base map is divided into multiple topographic map units of a second scale according to preset longitude and latitude differences; the first scale is smaller than the second scale.
[0033] The topographic map is encoded as a combination of map number, row number, and column number. The map number indicates the size of the second scale, the row number indicates the row in which the topographic map unit is located on the base map, and the column number indicates the column in which the topographic map unit is located on the base map. Both the row number and the column number have a set length.
[0034] The set length is 4 digits. If the row number or column number is less than 4 digits, zeros are added in front.
[0035] If the first scale is 1:1,000,000, then a topographic map at a scale of 1:1,000,000 is selected as the base map sheet. The second scale is a 1:1,000 topographic map with a longitude difference of 18.75″ and a latitude difference of 12.5″.
[0036] For example, a 1:1,000,000 topographic map has the map number J50, and the 1:1000 topographic map contained therein has the map number J50J01800109. Here, "J50" represents the map number of the 1:1,000,000 topographic map, "J" represents the 1:1000 scale code, "0180" represents the row number, and "0109" represents the column number.
[0037] The river geomorphological features include the river segment type and geomorphological type where the topographic map unit is located.
[0038] The types of river sections include: straight river sections, braided river sections, meandering river sections, water network river sections, and river deltas; The landform types include: dry riverbeds, deep pools, shallow beaches, shoals, river islands, and riverbank wetlands.
[0039] The classification system of river section type and landform type is shown in Table 1.
[0040] Table 1 Classification of River Section Types and Landform Types
[0041] This application classifies river geomorphological features corresponding to each grid unit (topographic map unit) based on remote sensing data and field survey results. The classification is based on river geomorphological features, which include river segment type and river geomorphological characteristics. For example, the geomorphology of survey point 1 belongs to the riverbank of a straight river segment that is flooded every year, survey point 2 belongs to the riverbank of a braided river segment that is flooded every year, and survey point 3 belongs to the backwater of a braided river segment.
[0042] The geomorphological coding uses a combination of river type and geomorphological type. In this case, the river type is represented by the first letter of its English name, and the geomorphological types are numbered in order of lowest riverbed elevation. Important habitats are coded using the first letter of their English names, such as spawning grounds and wintering grounds. For example, the geomorphological code for survey point 1 is S7, the geomorphological code for survey point 2 is B7, and the geomorphological code for survey point 3 is B6S.
[0043] The important habitat identifier is also used to indicate the important habitat function when the corresponding topographic map unit is a river landform with a preset important habitat function. The important habitat function includes fish spawning grounds and overwintering grounds.
[0044] The combined code is a combination of "river section type + river geomorphological features + important habitat type".
[0045] For river landforms with important habitat functions, such as fish spawning grounds and overwintering grounds, the landform coding should include important habitat function, becoming a combination of three characteristic meanings: river section type, river landform characteristics, and important habitat function.
[0046] The combined coding forms a unique label code. The format of this combined code is: [latitude and longitude grid code] - [landform type code] - [important habitat identifier]. If the important habitat identifier is empty, it indicates that the topographic map unit is not a river landform with the preset important habitat function. If the topographic map unit is a river landform with the preset important habitat function, then the important habitat identifier indicates the important habitat function. The label code for survey point 1 is J47J1077219134-S7, the label code for survey point 2 is J47J1056319355-B7, and the label code for survey point 3 is J48J1051010467-B6S, where S is the important habitat identifier indicating the important habitat function.
[0047] By using uniquely labeled combination codes, the specific habitats of each river section are accurately marked, ensuring the consistency of data across different regions and times, and facilitating the integration and comparison of data across regions and times.
[0048] The generated combined codes and related habitat data are stored in a database. Each combined code corresponds to a specific habitat characteristic, including substrate type, flow velocity, slope, etc., ensuring accurate data storage.
[0049] The combined codes of each topographic map unit and the river geomorphological features are stored in a geographic information system (GIS) based on geographic coordinates. The GIS is used to query various features, such as geomorphological features, of each river habitat. Specifically, the combined codes, geographic coordinates, and river geomorphological features of each topographic map unit are stored as a data base in the GIS database, which also stores other information such as hydrological and biological data.
[0050] This application utilizes a GIS platform for the storage, retrieval, and spatial analysis of habitat data, enabling precise labeling of river habitats and ensuring data consistency and comparability. Spatial analysis combines habitat labeling data with ecological data such as water quality and ecologically sensitive areas to conduct multi-dimensional ecological assessments, thereby providing data support for watershed management and ecological protection. Through a unified coding standard, data sharing and cross-platform collaboration among different departments and regions are achieved, improving the efficiency of watershed-level management.
[0051] In one exemplary embodiment, a river habitat data management method of this application includes the following steps.
[0052] Step 1: Identify the river habitat areas to be labeled and their regional delineation codes. Based on remote sensing imagery (e.g., historical Google Earth imagery), determine the river areas requiring habitat labeling, encompassing the river's watershed and specific survey area. For example... Figure 2 As shown, the geographical locations of the Datong River, a tributary of the Yellow River, and its survey points are displayed.
[0053] Based on the latitude and longitude of the survey points, a 1:1,000,000 scale topographic map is used for regional division and coding. The specific process is as follows: first, the corresponding 1:1,000,000 topographic map number is calculated using the geographic coordinates, and each topographic map is divided into 1152 rows and 1152 columns. The final code is then calculated based on the row and column numbers.
[0054] For example, the latitude and longitude of survey point 1 are 37°83′60″N, 100°39′10″E, and the calculated grid code is: J47J1077219134.
[0055] Step Two: Determine River Geomorphological Classification and Coding. Based on the actual river geomorphological characteristics of the survey points and in conjunction with the river geomorphological classification system shown in Table 1, classify and code the river geomorphology of each survey point. For example, ... Figure 3 As shown, at survey point 1, one side of the valley is shallower than the other, and the right bank is bedrock, forming a steep cliff; the left bank is relatively gentle and has vertical undercuts, and the landform code is C1.
[0056] The other two survey points were classified using a similar method, and their landform codes were D3b and A3. Figure 4 and Figure 5 It shows the actual situation of these landforms and reflects the geographical characteristics of the survey points.
[0057] Step 3: Combine codes to form a unique label code. Combine the regional grid code (topographic map code) obtained in Step 1 with the geomorphic code in Step 2 to form a unique label code. For example, the label codes for the three survey points are: J47J1077219134-C1, J47J1056319355-D3b, and J48J1051010467-A3.
[0058] Step 4: Establish a habitat coding system; store the generated combination codes and related habitat data in a database, and use a GIS system for storage and management. Each combination code corresponds to the habitat characteristics of a specific location, including information such as substrate type, flow velocity, and slope. This coding system ensures accurate data storage and efficient retrieval, facilitating management and analysis. Managing and sharing data through a GIS platform improves watershed-level management efficiency.
