[0002] The ecological protection red line refers to a region with special important ecological function within the scope of ecological space and must be strictly protected, is the bottom line and lifeline for guaranteeing and maintaining national ecological security, and usually includes ecological function important regions with important water conservation, biodiversity maintenance, soil and water conservation, wind prevention and sand fixation, and coastal ecological stability, and ecological environment sensitive and fragile regions such as water and soil loss, land desertification, rocky desertification, and salinization. The ecological protection red line aims to establish the most strict ecological protection system, and proposes higher regulatory requirements for ecological function guarantee, environmental quality safety, and natural resource utilization, so as to promote the balance of population, resources and environment, and the unity of economic, social and ecological benefits.

[0003] The ecological protection red line region surveying work mainly includes surveying and periodic measuring of the boundary of the delimited ecological protection red line region, and the existing surveying method mainly determines the measuring point from the remote sensing image base map and the ecological protection red line map, then goes to the measuring point for field surveying by manually carrying the GIS data acquisition device or other image and position acquisition device, then performs on-site construction of boundary post setting, and finally performs surveying and mapping re-surveying. The whole process is mainly manual, and a large amount of manpower is needed, and the efficiency is low. SUMMARY

[0033] The present invention will be further described in detail below with reference to specific embodiments, but the implementation of the present invention is not limited thereto.

[0034] Example 1

[0035] This embodiment provides a method for demarcating ecological protection red lines, including the following steps:

[0036] Step 10: Input the coordinates of the pre-survey boundary points and the outline of the red line range of the annotation base map into the survey boundary marker management subsystem in the mobile terminal; the annotation base map is the base map after dividing the ecological protection red line base map into sections; the coordinates of the pre-survey boundary points are the position coordinates of the preset boundary markers extracted from the annotation base map;

[0037] Step 20: The boundary demarcation and marker management subsystem generates a preliminary reconnaissance base map; the preliminary reconnaissance base map displays the coordinates of the pre-survey boundary points and the outline of the red line range marked on the base map;

[0038] Step 30: Conduct the first reconnaissance based on the preliminary reconnaissance base map and the first current location coordinates displayed by the boundary marker management subsystem to determine the modified location of the pre-survey boundary point coordinates, and input the modified location into the boundary marker management subsystem;

[0039] Step 40: Perform a secondary reconnaissance based on the secondary reconnaissance base map generated by the modified location to obtain reconnaissance information and replacement coordinates of boundary marker points; the secondary reconnaissance base map displays the modified coordinates of the pre-survey boundary points and the outline of the red line range of the modified annotation base map;

[0040] Step 50: The geographic information subsystem modifies and replaces the coordinates to be replaced on the secondary reconnaissance base map according to the reconnaissance information and replacement coordinates to obtain the preliminary boundary marker coordinates, and encodes the preliminary boundary marker coordinates to obtain the corresponding boundary marker number.

[0041] Step 60: Update the coordinates of the pre-surveyed boundary points in the boundary marker management subsystem to the coordinates of the preliminary boundary markers, import the boundary marker numbers and reconnaissance information into the boundary marker management subsystem, and update the preliminary reconnaissance base map to the boundary marker base map according to the preliminary boundary marker coordinates.

[0042] Step 70: Set up the markers on-site according to the boundary marker location map and the second current location coordinates displayed by the boundary marker management subsystem;

[0043] Step 80: Based on the preliminary boundary marker coordinates, boundary marker numbers, and geographic information data of the ecological protection red line base map, a construction base map is created, and physical boundary markers with QR codes corresponding to the boundary marker numbers are created; the QR codes indicate the reconnaissance information and the attribute information of the corresponding ecological protection red line.

[0044] Step 90: Install the physical boundary stakes at the positions indicated by the coordinates of the preliminary boundary stake points according to the construction base plan;

[0045] Step 100: Obtain the coordinates of the completed boundary markers and their attribute information through as-built surveying, and collect multiple images of the erected boundary markers.

[0046] Step 110: Update the preliminary boundary marker coordinates and reconnaissance information in the boundary marker management subsystem according to the coordinates and attribute information of the completed boundary markers. Store the boundary marker images in the database of the boundary marker management subsystem and generate boundary marker result information.

[0047] In this embodiment, the boundary demarcation and marker management subsystem can display the coordinates of pre-surveyed boundary points and the outline of the red line range on the base map, showing their real-time location and storing relevant information. This eliminates the need for paper maps, facilitating field surveys and improving the convenience of the survey process, thus further enhancing the efficiency of boundary demarcation and marker work. Simultaneously, the subsystem also allows viewing the coordinates and attribute information of completed boundary markers, facilitating rapid review of the ecological red line boundary demarcation and marker results, demonstrating a high degree of digitalization.

[0048] Example 2

[0049] This embodiment provides a method for demarcating ecological protection red lines, the method including:

[0050] Step 201: The sheet division module generates sheet frames based on the target paper size and margins. After setting the target paper size, margins, and sheet name in the sheet division module, it can generate sheet frames of the corresponding size. For example... Figure 1 and Figure 2 As shown.

[0051] Step 202: Preset administrative region border annotations in the map segmentation module. Information regarding these annotations is stored in the database set of the combined chart. Specifically, this involves setting the combined chart's layer, the administrative region layer, the distance of the annotations from the border, the distance of the annotations from the intersection point, and the annotation font size. For example... Figure 3 As shown.

[0052] Step 203: Using the map sheet division module, batch print the ecological protection red line base map into multiple labeled base maps based on the storage location of the map sheet frames. During batch printing, administrative region border annotations are generated on the labeled base maps. For standard map sheet divisions, fixed paper can be selected for batch printing. After setting the output path, batch printing begins, as follows... Figure 4 As shown. Before batch printing, each figure after being divided into sheets can automatically match its name, legend, and related information.

[0053] In this embodiment, the boundary demarcation and marking work needs to be carried out by region. The ecological protection red line base map is divided into sheets as needed, increasing the scale of the divided map to facilitate subsequent work. During the boundary demarcation process, the corresponding marked base map can be used. The ecological protection red line base map is based on a high-resolution digital orthophoto map, supplemented by digital elevation data.

[0054] Prepare a digital map of the "red line-image" area at a scale of 1:100,000 or 1:50,000.

[0055] Step 204: Extract the coordinates of the pre-survey boundary points from the marked base map using the extraction module based on either the POINT_REMOVE algorithm or the BEND_SIMPLIFY algorithm. The coordinates of the pre-survey boundary points are the location coordinates of preset boundary markers extracted from the ecological protection red line vector data in the marked base map.

[0056] In this embodiment, the method of obtaining the coordinates of the pre-surveyed boundary points by using a graphical method during the office processing is too time-consuming. However, after converting the area data of the ecological protection red line into point elements, the number of point data is very large. It is necessary to filter the points according to the corresponding algorithm to determine the location of the preset boundary markers and signs of key sections and important turning points of the ecological protection red line.

[0057] (1) POINT_REMOV Algorithm: This algorithm simplifies data by identifying and removing relatively redundant vertices so they can be displayed at a smaller scale. It's a convenient algorithm for simplifying lines. It retains the key points that make up the basic shape of the line while removing all other points. The algorithm starts by connecting the endpoints of the line features using trend lines. First, it measures the vertical distance from each vertex to the trend line. Vertexes whose distance from the trend line is less than the tolerance are deleted. The line feature breaks first at the vertex farthest from the trend line, creating two new trend lines. Then, it measures the vertical distance from the remaining vertexes to these two lines, continuing until all vertexes whose distance from the trend line is less than the tolerance are deleted. This is the fastest simplification algorithm in this tool. This algorithm is very effective for data compression and eliminating redundant details, but the generated lines may contain unnecessary sharp corners and edges, reducing the quality of the lines. It is typically used for data compression or coarse simplification. As the tolerance increases, the number of angular parts in the generated lines will increase significantly. This algorithm is based on the Douglas-Puk (1973) algorithm.

[0058] For the POINT_REMOVE algorithm, the tolerance represents the maximum permissible vertical distance between each inflection point and the newly created line.

[0059] (2) BEND_SIMPLIFY Algorithm: This algorithm identifies and eliminates relatively unimportant bends, retaining key bends in the line to simplify the data for display at a smaller scale. Linear features can be viewed as a series of bends (Wang, 1996), where each bend has the same corner sign at its consecutive folds. Several geometric properties of each bend can be compared to their corresponding properties of a reference semicircle with a diameter equal to a specified simplification tolerance. These measurements are used to determine whether to retain or eliminate the bend, i.e., replace it with a baseline (the line connecting the bend's endpoints). This simplification is iterative; therefore, smaller bends may "disappear" in earlier iterations, resulting in larger bends. This results in a line that more closely resembles the original line in general shape, with higher cartographic quality than point removal. This option is based on the algorithm defined by Wang and Müller (1998). Compared to the POINT_REMOVE algorithm, this algorithm produces results closer to the input geometry but may require more processing time. This method is slower but generally produces results closer to the original features.

[0060] For the BEND_SIMPLIFY algorithm, the tolerance is represented by the diameter of the circle that is approximately effectively bent.

[0061] Step 205: Input the coordinates of the pre-surveyed boundary points and the outline of the red line range of the base map into the boundary demarcation and marking management subsystem in the mobile terminal. The base map is the base map after the ecological protection red line base map has been divided into sheets.

[0062] Step 206: The boundary demarcation and marking management subsystem generates a preliminary reconnaissance base map based on the coordinates of the pre-demarcation boundary points and the outline of the red line range on the marked base map. The preliminary reconnaissance base map displays the coordinates of the pre-demarcation boundary points and the outline of the red line range on the marked base map. The boundary demarcation and marking management subsystem has three commonly used maps pre-set: satellite imagery, standard map, and topographic map. The coordinates of the pre-demarcation boundary points and the outline of the red line range on the marked base map can be displayed on these three maps respectively to generate the preliminary reconnaissance base map for use in preliminary reconnaissance.

[0063] Step 207: Conduct the first reconnaissance based on the preliminary reconnaissance map and the first current location coordinates displayed by the demarcation and marker management subsystem to determine the modified locations of the pre-survey boundary point coordinates, and input the modified locations into the demarcation and marker management subsystem. In this embodiment, field workers can use a mobile terminal equipped with the demarcation and marker management subsystem to conduct the first field reconnaissance. The positioning module of the demarcation and marker management subsystem can locate the current location of the field workers. For example, if the demarcation and marker management subsystem displays the location as covered by the red line, but the actual situation is a village with a large population, and this area is not at the red line boundary, and there are no pre-survey boundary points in the demarcation and marker management subsystem, then this location is incorrect and needs to be modified and supplemented. During modification, first store the current location in the recording module of the demarcation and marker management subsystem, then upload photos through the image acquisition module of the demarcation and marker management subsystem, and enter relevant information. Locations with correct information that do not need modification do not require operation. The main task of the first reconnaissance is to identify areas that are disputed, difficult to demarcate, or that should be protected but are not adequately protected during the demarcation and marker work. The current location information in the recording module is latitude and longitude, and the current location information in the recording module can be extracted for use by the geographic information subsystem.

[0064] Step 208: Perform a secondary reconnaissance survey based on the secondary reconnaissance base map generated from the modified location to obtain reconnaissance information and replacement coordinates of boundary marker points. The secondary reconnaissance base map displays the modified coordinates of the pre-survey boundary points and the outline of the red line range of the modified marked base map.

[0065] In this embodiment, step 208 includes the following steps: step 2081-step 2082.

[0066] Step 2081: The geographic information system modifies the coordinates of the pre-survey boundary points and the outline of the red line on the ecological protection red line base map according to the modified location, generating a secondary reconnaissance base map. The geographic information system acquires the latest remote sensing image of the area where the modified location is located, modifies the point coordinates based on the remote sensing image, and then generates the secondary reconnaissance base map.

[0067] Step 2082: Conduct a secondary reconnaissance survey based on the secondary reconnaissance base map to obtain reconnaissance information and replacement coordinates for boundary marker points. The secondary reconnaissance survey uses a total station and a paper-based secondary reconnaissance base map to conduct a comprehensive, point-by-point survey. The modified and unmodified coordinates of the pre-surveyed boundary marker points from the first reconnaissance are measured on-site to obtain replacement coordinates for the boundary marker points, and the reconnaissance information is stored. The replacement coordinates are the actual measured coordinates. The reconnaissance information includes preliminary boundary marker attribute information and relevant explanatory information. Preliminary boundary marker attribute information includes the boundary marker number (marking), boundary marker latitude and longitude coordinates, boundary marker location, ownership unit, whether a sign is attached, location and name of landmarks, and distance from landmarks. Relevant explanatory information may include descriptions of unresolved issues encountered during the secondary reconnaissance survey. The reconnaissance information can be stored electronically on devices such as mobile terminals.

[0068] The working base map used in the secondary reconnaissance survey is the working base map after being divided into sections. The specific method for dividing the secondary reconnaissance base map into sections is the same as steps 201-203 above.

[0069] Step 209: Using the geographic information subsystem, the coordinates to be replaced on the secondary reconnaissance base map are modified and replaced based on the reconnaissance information and replacement coordinates to obtain the preliminary boundary marker coordinates. These preliminary boundary marker coordinates are then coded to obtain corresponding boundary marker numbers. After the secondary survey and reconnaissance, inaccurate coordinates on the secondary reconnaissance base map are replaced with replacement coordinates. The coordinates that have not been changed and those that have been changed are used as the preliminary boundary marker coordinates. After the preliminary boundary marker coordinates are determined, they are coded in a clockwise order, starting from the northernmost point. Each point corresponds to a unique boundary marker number. These boundary marker numbers are then collected and transferred to the subsequent physical boundary marker production.

[0070] Step 210: Update the coordinates of the pre-surveyed boundary points in the boundary demarcation and marker management subsystem to the coordinates of the preliminary boundary markers. Import the boundary marker numbers and reconnaissance information into the boundary demarcation and marker management subsystem. The boundary demarcation and marker management subsystem then updates the preliminary reconnaissance base map to the boundary marker base map based on the preliminary boundary marker coordinates. The reconnaissance information, including preliminary boundary marker attribute information and related explanatory information, can be viewed in the query module of the boundary demarcation and marker management subsystem.

[0071] Step 211: Based on the boundary marker location map and the second current location coordinates displayed by the boundary marker management subsystem, erect a marker on-site. The positioning module of the boundary marker management subsystem locates the second current location of the field staff. The second current location is displayed on the boundary marker location map. When the second current location coincides with the coordinates of the preliminary boundary marker location, check whether a marker is attached in the preliminary boundary marker attribute information. If so, erect a marker at the second current location.

[0072] In steps 201-211 above, the surveying and mapping marker management subsystem is used for relevant field processing and data storage, which reduces the use of paper maps and facilitates data storage and data processing in the office.

[0073] Step 212: Based on the geographic information data of the preliminary boundary marker coordinates, boundary marker numbers, and the ecological protection red line base map, a construction base map is created, and physical boundary markers with QR codes corresponding to the boundary marker numbers are produced. The QR codes indicate the reconnaissance information and the attribute information of the corresponding ecological protection red line. The attribute information of the corresponding ecological protection red line includes the administrative region, ecological protection type, whether there is a nature reserve, and the ownership unit. The preliminary boundary marker coordinates indicate the location of the physical boundary markers. The preliminary boundary marker coordinates include X, Y, and Z coordinates. One set of X, Y, and Z coordinates corresponds to one physical boundary marker. X represents longitude, Y represents latitude, and Z represents altitude. In this embodiment, the construction base map is created using the geographic information subsystem based on basic data such as high-definition imagery, land survey data, and digital elevation data. The preliminary boundary marker coordinates are marked on the construction base map. The boundary marker numbers are determined based on the coding of the preliminary boundary marker coordinates. After organizing the boundary marker numbers, physical boundary markers are produced. After marking the coordinates of the preliminary boundary markers on the construction base map, a final inspection and reconnaissance can be carried out to confirm the location of the points corresponding to the coordinates of the preliminary boundary markers, the construction base map, the construction location, and other information.

[0074] In this embodiment, a QR code is placed on the top of the physical boundary marker. Scanning the QR code allows access to the survey information of the physical boundary marker, including preliminary boundary marker attribute information and related explanatory information. The information indicated in the QR code may also include news about ecological protection red lines, methods for delineating ecological protection red lines, methods for surveying and marking ecological protection red lines, management methods for ecological protection red lines, and the surveying and marking management subsystem. After the physical boundary marker construction is completed, scanning the QR code using the "scan" function on a mobile device will redirect to the ecological protection red line webpage. Clicking the "Ecological Protection Red Line Boundary Marker Inquiry" icon on the page, turning on the phone's location function or selecting the administrative region, and then entering the physical boundary marker number to be queried will display the detailed completed boundary marker attribute information.

[0075] Step 213: Install physical boundary markers at the locations indicated by the coordinates of the preliminary boundary marker points according to the construction base map. Before construction, it is necessary to provide operational training to the construction personnel. The training content includes: (1) understanding the working base map; (2) using the boundary marker management subsystem; (3) construction techniques and key points; and (4) requirements for submitting construction results.

[0076] The specific steps of step 213 include: step 2131-step 2132.

[0077] Step 2131: Construction personnel conduct layout based on the construction base map and satellite images, standard maps, and topographic maps in the boundary demarcation and marking management subsystem. During layout and construction, the current construction location can be determined by the positioning module, and the current construction location can be displayed on the map in the boundary demarcation and marking management subsystem, ensuring the accuracy of the construction location.

[0078] The construction base map used during construction is a working base map after the construction base map has been divided into sections. The specific sectioning method is the same as steps 201-203.

[0079] Step 2132: Construction workers install physical boundary stakes at the designated layout points. This includes adjusting layout points where physical boundary stakes cannot be installed based on pre-defined conditions. For example... Figure 5 and Figure 6 As shown, during the installation of boundary markers, to ensure their stability, multiple installation holes can be drilled on the lower side wall of the physical boundary marker A. A reinforcing bar B can be inserted into each hole, and stones can be placed on top of the reinforcing bar B to firmly anchor the physical boundary marker in the ground. Alternatively, if construction encounters limitations due to the surrounding environment, uneven roads, or rocks after underground excavation, the junction between the physical boundary marker and the ground can be filled with soil, with the soil mound not exceeding 10cm above the ground surface.

[0080] During construction, layout points where it is impossible to install physical boundary markers are generally located in areas where construction is impossible. These areas are typically characterized by shallow underground features such as mountainsides or rocks that are difficult to excavate, or by human-caused obstructions. Construction sites may also be located on residential land or other areas not under state ownership. The specific adjustment method is to move the markers back and forth along the ecological protection red line boundary, not exceeding 100 meters.

[0081] Step 214: The as-built survey obtains the coordinates and attribute information of the completed boundary markers, and acquires multiple images of the erected boundary markers. The attribute information of the completed boundary markers includes the boundary marker number (marking), the latitude and longitude coordinates of the boundary marker, the location of the boundary marker, the ownership unit, whether a signboard is attached, the location and name of the landmark, and the distance to the landmark.

[0082] Due to factors such as the influence of natural boundary lines and adjustments to the final construction point locations, the construction point locations in the as-built survey may deviate slightly from the initial construction base map data. Therefore, the red line boundary lines need to be fine-tuned to ensure consistency with the final demarcation and marking results. The office staff first create the adjusted ecological red line range. Simultaneously, compared to the original ecological protection red line, they create an "imported" map patch layer and an "exported" map patch layer. An erasing operation is then performed based on the original ecological red line range and the adjusted range to obtain the adjusted map patches. Imported map patch = "Adjusted" erased "Original". Exported map patch = "Original" erased "Adjusted".

[0083] During the construction process, the original construction process ((1) accurate layout and marking; (2) construction according to the marking; (3) feedback of internal adjustments for areas where construction cannot proceed smoothly; (4) re-layout, marking and construction until construction proceeds smoothly) was adjusted. For areas where construction cannot proceed smoothly, there is no need to provide feedback of internal adjustments, thus shortening the operation cycle.

[0084] Step 215: Update the preliminary boundary marker coordinates and reconnaissance information in the boundary marker management subsystem according to the coordinates and attribute information of the completed boundary markers. Store the boundary marker images in the database of the boundary marker management subsystem and generate boundary marker result information.

[0085] The specific steps of step 215 include:

[0086] Step 2151: Update the preliminary boundary marker coordinates and reconnaissance information in the boundary demarcation and marker management subsystem based on the completed boundary marker coordinates and attribute information. The completed boundary marker attribute information is used to update the preliminary boundary marker attribute information in the reconnaissance information. After the data in the boundary demarcation and marker management subsystem is updated, a base map of the actual boundary marker locations can be generated, and the coordinates of the completed boundary markers and the outline of the red line range can be displayed on satellite imagery, standard maps, and topographic maps, respectively. All data in the boundary demarcation and marker management subsystem is stored in its database.

[0087] Step 2152: Number multiple boundary marker images according to the boundary marker number in the attribute information of the completed boundary markers using the numbering module.

[0088] The specific steps of step 2152 include: steps 21521-21524.

[0089] Step 21521: In the display interface of the numbering module, add the boundary marker images from the folders to be numbered to the renaming queue; wherein, each folder stores multiple boundary marker images for a single physical boundary marker. The boundary marker image corresponding to each physical boundary marker is stored in a corresponding folder. For example... Figure 7 As shown.

[0090] Step 21522: Preset renaming conditions, preset deletion conditions, preset red line codes, preset boundary marker numbers, and preset end sequence code conditions. For example... Figure 8 , Figure 9 and Figure 10 As shown, in this step, the deletion condition is to clear the original filename of the boundary marker image before numbering. The preset red line code and boundary marker number are set to a uniform red line code and boundary marker number for the insertion numbering condition, and the sequence number at the end is set.

[0091] Step 21523 triggers the rename button on the display interface of the numbering module.

[0092] Step 21524: The numbering module renumbers the multiple boundary marker images in the folder and displays the numbering results on the numbering module's display interface. The numbering module's display interface can show two parts: one part is the content of the aforementioned preset conditions, and the other part is the numbering status, such as... Figure 11 As shown.

[0093] Step 2153: The results processing module generates corresponding boundary marker result information for each physical boundary marker based on the updated preliminary boundary marker coordinates, updated reconnaissance information, boundary marker numbers, and boundary marker images with numbers.

[0094] The specific steps of step 2153 include:

[0095] Step 21531: The results processing module extracts the corresponding boundary marker data from the database of the boundary marker management subsystem based on the boundary marker number. The boundary marker data includes: updated preliminary boundary marker coordinates and updated reconnaissance information. Each boundary marker number in the area is unique; relevant information is retrieved from the database based on the boundary marker number.

[0096] Step 21532: Generate a boundary marker information table based on the boundary marker data. The boundary marker information table includes information such as the ecological protection red line code, boundary marker number (engraved), distance between the boundary marker and the landmark, location of the landmark, coordinates (latitude and longitude), boundary marker image, simplified map of the boundary marker location, and remarks. Figure 12 As shown. The sketch map of the boundary marker locations is extracted from the actual boundary marker location base map.

[0097] Step 21533: Extract the corresponding boundary marker image based on the boundary marker number, and insert the boundary marker image into the boundary marker information table to generate boundary marker result information.
