BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0024] The design method of the green park with health and healing functions has the following specific steps:

[0025] S1, scan the target area through the LiDAR system to obtain three-dimensional point cloud data;

[0026] The LiDAR system is a remote sensing technology that determines distance by emitting laser pulses and measuring the time it takes for these pulses to reflect from a target object. Based on this principle, LiDAR can create high-resolution three-dimensional point cloud data that represents the position and shape of objects in the measured environment.

[0027] In actual use, the LiDAR system can be mounted on the ground to scan the target area, or it can be mounted on a drone to scan the target area. The choice can be made based on the actual terrain environment and terrain area. During the scanning process, the LiDAR system will emit a large number of laser pulses into the surrounding environment and record the time and intensity of each pulse return.

[0028] S2, classifying the point cloud data using software tools to distinguish between ground points and non-ground points, and building a digital terrain model based on the ground points and a digital surface model based on the highest point among the non-ground points;

[0029] The original LiDAR data is usually in binary format and can be converted into a readable point cloud format, such as LAS or LAZ file; the software tool for analyzing point cloud data can be one of CloudCompare, Leica Cyclone, and ESRIArcGIS. The above software tools are all existing technologies and will not be described in detail in this application; wherein, in a location information, the ground point is the lowest point of this location information, and a digital ground model can be established using the set of all acquired ground points to simulate the terrain structure of the target area; the other point cloud data of the location information of the non-ground point except the ground point, including but not limited to the highest point, can be used to establish a digital surface model using the set of the highest points of all acquired non-ground points to simulate the highest layer of the ground structure in the target area.

[0030] S3, dividing the target area into a plurality of grid areas, and generating first information and second information corresponding to each grid area based on the point cloud data within the grid area; wherein the first information is the height of the highest vegetation in the current grid area, and the second information is the density of vegetation in the current grid area;

[0031] The height of vegetation can be obtained by subtracting the value of the digital terrain model from the value of the digital surface model at the same location, because the value of the digital surface model represents the crown of vegetation, and the digital terrain model represents the ground. The value of the crown minus the value of the ground represents the height of vegetation, and the first information is the height of the highest vegetation in a grid area; the density of vegetation can be obtained by the distribution density of point cloud data at a certain height in the current area. At a certain height, one point cloud data represents one vegetation. After calculating the number of vegetation in the grid area, the ratio of the number of vegetation to the area of ​​the current grid area is the density value of vegetation in the current grid area.

[0032] S4, classifying the grid area into a core area, a buffer area, and a functional area according to the first information and the second information of the grid area and a preset threshold, and dividing the grid area into a core area, a buffer area, and a functional area in descending order of ecological primitiveness;

[0033] S41, determining whether the first information value is greater than the first information threshold of the core area, if so, dividing the grid area into the core area, if not, proceeding to S42;

[0034] S42, determining whether the second information value is greater than the second information threshold of the core area, if so, dividing the grid area into the core area, if not, proceeding to S43;

[0035] S43, determining whether the first information value is greater than the first information threshold of the buffer area, if so, dividing the grid area into the buffer area, if not, proceeding to S44;

[0036] S44, determining whether the second information value is greater than the second information threshold of the buffer area, if so, dividing the grid area into the buffer area, if not, dividing the grid area into the functional area;

[0037] Example:

[0038] The first information threshold of the preset core area is 5m, and the second information threshold is 5 plants / ㎡;

[0039] The first information threshold of the preset buffer area is 3m, and the second information threshold is 3 plants / ㎡;

[0040] When the first information in the grid area is greater than 5m and the second information is greater than 5 plants / ㎡, the grid area is divided into the core area. For example, if the first information is 7m and the second information is 6 plants / ㎡;

[0041] When the first information in the grid area is greater than 5m and the second information is less than 5 plants / ㎡, the grid area is divided into the core area. For example, if the first information is 7m and the second information is 4 plants / ㎡;

[0042] When the first information in the grid area is less than 5m and the second information is greater than 5 plants / ㎡, the grid area is divided into the core area. For example, if the first information is 4m and the second information is 6 plants / ㎡;

[0043] In summary, that is, when any one of the first information and the second information of a grid area is greater than the preset core area threshold value, the grid area is divided into the core area.

[0044] When the first information in the grid area is less than 5m but greater than 3m, and the second information is less than 5 plants / ㎡ but greater than 3 plants / ㎡, the grid area is divided into a buffer area. For example, the first information is 4m and the second information is 4 plants / ㎡.

[0045] When the first information in the grid area is less than 5m but greater than 3m, and the second information is less than 3 plants / ㎡, the grid area is divided into a buffer area. For example, if the first information is 4m and the second information is 2 plants / ㎡;

[0046] When the first information in the grid area is less than 3m and the second information is less than 5 plants / ㎡ but greater than 3 plants / ㎡, the grid area is divided into a buffer area. For example, the first information is 2m and the second information is 4 plants / ㎡.

[0047] In summary, when the first information and the second information of the grid area are both smaller than the core area threshold, if either the first information or the second information is larger than the preset buffer area threshold, the grid area is divided into the buffer area.

[0048] When the first information in the grid area is less than 3m and the second information is less than 3 plants / ㎡, the grid area is divided into functional areas. For example, the first information is 2m and the second information is 2 plants / ㎡.

[0049] In the above, the priority of vegetation height is set before vegetation density, that is, the comparison priority of the first information is higher than the second information, so that the tall vegetation can be retained to the maximum extent and the ecological core area can be established based on it.

[0050] S5: Grid areas of the same level are connected and border each other to form ecological core areas, ecological buffer areas and ecological functional areas within the target area; among them, the ecological buffer areas are located between the ecological core areas and the ecological functional areas.

[0051] In other words, several core areas are interconnected and border each other to form an ecological core area. In the ecological core area, the height and density of vegetation are relatively high, and low development is implemented on it to maximize the preservation of the natural original terrain, landforms and natural conditions.

[0052] Several buffer areas are interconnected and bordered to form an ecological buffer zone. In the ecological buffer zone, the height and density of vegetation are relatively balanced, surrounding and protecting the ecological core area.

[0053] Several functional areas are interconnected and bordered to form an ecological functional zone. In the ecological functional zone, the height and density of vegetation are relatively low, and functional areas for human activities can be developed.

[0054] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
