Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

In order to facilitate understanding of this embodiment, the embodiment of the present invention is introduced in detail below.

Example 1:

Figure 1 is a flow chart of a method for determining the priority of comprehensive management of small watersheds provided in Embodiment 1 of the present invention.

Referring to Figure 1, the method for determining the priority of comprehensive management of small watersheds includes:

Step S101: Obtain dynamic monitoring data of soil and water loss and small watershed boundary data of the area to be treated.

Here, the dynamic monitoring data of soil and water loss are obtained from the area to be treated within a period of time monitored by 2m remote sensing images.

The dynamic monitoring data of water and soil loss include: the total area of water and soil loss, land use, vegetation coverage and slope; among them, the land use includes land use type and land use patch area; the total area of water and soil loss includes the total area of water and soil loss , soil erosion intensity and area of each graded intensity. The slope is extracted based on a 1:50,000 digital elevation model.

Land use types include bare gravel plots, sloping farmland, orchards, tea gardens, other gardens, woodland, shrubland, other woodland, grassland, construction and transportation land, etc.

The land use map patch area is to divide the land units (plots) with basically the same landforms, land use types, and water and soil erosion types into one category, use it as the basis for survey units, and then draw the units on the topographic map to form a map The area corresponding to the spot. The land use patch area is used to determine whether the land use type is concentrated and contiguous or dispersed and fragmented.

Vegetation coverage includes low coverage, medium coverage, medium-high coverage, and high coverage.

The small watershed boundary data is the demarcation data of the area to be treated provided by the relevant surveying and mapping departments. It uses 1:10,000 basic geographical information data as the working base map and is formed based on the 1:50,000 digital elevation model.

Step S102: Based on the dynamic monitoring data of water and soil loss and the preset treatment area division method, determine the total area that should be treated in the area to be treated; the total area that should be treated includes the total area that can be fully treated and the total area that cannot be completely treated.

In one embodiment, referring to Figure 2, step S102 includes:

Step S201: Determine the areas that do not need to be treated and the total area that should be treated in the area to be treated based on the dynamic monitoring data of water and soil loss and the preset standards for areas that do not need to be treated.

Here, the area that does not require treatment refers to the area of water and soil erosion that has no adverse impact or has a small impact on production, life, and ecology, does not require special treatment, and is difficult to recover and eliminate naturally.

The total area that should be treated refers to the area of water and soil erosion that has adverse effects on production, life, and ecology and requires the implementation of targeted prevention and control measures.

In one embodiment, referring to Figure 3, step S201 includes:

Step S301: Obtain the land use patch area of the area to be treated.

Step S302: Determine the area in the area to be treated where the land use patch area is concentrated and contiguous bare rock and gravel blocks as the area that does not require treatment.

Here, it is determined that the area that does not need to be treated is B.

Step S303: Subtract the total soil and water loss area and the area that does not need to be treated to obtain the total area that should be treated.

Here, determine the total area of soil and water loss as A, determine the total area that should be treated as C, and determine C=A-B.

Step S202, based on the dynamic monitoring data of water and soil loss and the total area that should be treated, obtain the total completely treatable area and the total incomplete treatable area corresponding to the area to be treated through simulation of the pre-trained governance area model.

Here, the total area C2 that cannot be completely treated refers to the area in the total area C that should be treated, but due to natural, economic, technical level, etc. restrictions, the soil erosion intensity cannot be completely controlled below mild after treatment. The total area C1 that can be completely treated refers to the area in the total area C that should be treated, and through comprehensive prevention and control based on local conditions and classified policies, the soil erosion intensity can be controlled to less than mild after treatment.

In one embodiment, the governance area model is trained in the following manner:

The historical governance area and the historical total area that should be managed, historical land use types, historical vegetation coverage and historical slope corresponding to the historical governance area are used as inputs, and the historical completely manageable area and the historical total incomplete control area corresponding to the historical governance area are used as inputs. Output, train the first network model until the preset training conditions are met, and the trained governance area model is obtained.

Here, the first network model is a neural network model. The constructed, calibrated, and verified control area model can determine the total area C1 that can be completely controlled and the total area C2 that cannot be completely controlled in the area to be treated based on the input dynamic monitoring data of water and soil loss.

Specifically, the total area C1 that can be completely treated is concentrated cultivated land along the slope with a slope of less than 2° and a field size of ≥1 hectare; orchards, tea gardens, other gardens, woodlands, shrublands, and other woodlands with a slope of less than 5° and less than or equal to the medium slope. Coverage; other grassland slopes are less than 3° and less than or equal to medium coverage.

The total area C2 that cannot be completely treated is scattered and broken sloping cultivated land with a slope greater than 2° or a field area of <1 hectare; orchards, tea gardens, other gardens, woodlands, shrublands, and other woodlands with a slope less than 5° and high coverage or medium-high coverage and the slope is greater than 5°; other grassland has a slope less than 3° and high coverage or medium coverage and a slope greater than 3°; construction and transportation land.

Step S103: Based on the dynamic monitoring data of water and soil loss and the total area that cannot be fully treated, obtain the treatment rate corresponding to each designated unit area in the total area that cannot be completely treated through simulation of the pre-trained regional treatment rate model.

Here, the designated unit area is the preset basic range of soil and water loss control, which can be set to 1 square kilometer.

The control rate n indicates the controllability of soil and water loss in the specified unit area. The higher the governance rate n, the higher the governanceability of the designated unit area. The lower the governance rate n, the lower the governanceability of the designated unit area.

In one embodiment, the regional governance rate model is trained in the following manner:

Taking the historical governance area, the historical soil erosion intensity, historical land use type, historical vegetation coverage and historical slope corresponding to the historical governance area as input, and the governance rate corresponding to each designated unit area in the historical governance area as the output, the second network The model is trained until the preset training conditions are met, and the trained regional governance rate model is obtained.

Here, the governance rate corresponding to each designated unit area in the historical governance area is set based on the actual governance situation of the historical governance area. Each designated unit area in the historical governance area corresponds to a fixed governance rate.

The second network model is a neural network model. The constructed, calibrated, and verified regional governance rate model can determine the governance rate n corresponding to each designated unit area in the total area C2 that cannot be completely harnessed based on the input dynamic monitoring data of soil and water loss.

Among them, the treatment rate n corresponding to each designated unit area can be the same or different, and is determined by the dynamic monitoring data of water and soil loss.

Specifically, when the land use types are the same, the higher the vegetation coverage, the smaller the treatment rate n; the greater the slope, the smaller the treatment rate n; the greater the soil erosion intensity, the greater the treatment rate n.

When land types are different but other conditions are the same, the governance rate n corresponding to land related to human activities (such as construction and transportation land) is smaller.

Step S104: Map the total area that can be completely treated and the total area that cannot be fully treated into the small watershed boundary data, and determine the corresponding small watershed in the small watershed boundary data based on the total area that can be completely treated, the total area that cannot be completely treated, and the treatment rate. Treatable area.

In one embodiment, referring to Figure 4, step S104 includes:

Step S401: Overlay the total area that can be completely treated and the area that cannot be completely treated with the small watershed boundary data to determine the completely treatable area and the area that cannot be completely treated corresponding to each small watershed in the area to be treated.

Here, based on the total area that can be completely governed and the total area that cannot be completely governed, a spatial distribution map of the total area that can be completely governed and the total area that cannot be completely governed can be obtained. Among them, the total area that can be fully governed and the total area that cannot be fully governed are distinguished by different colors. This spatial distribution map is superimposed with the small watershed boundary data to obtain a schematic diagram of the areas that can be completely treated and the areas that cannot be completely treated in the small watershed. Among them, there are completely controllable areas and incomplete control areas of different colors in the boundaries of each small watershed.

Step S402: Determine the completely treatable area and the incomplete treatable area corresponding to each small watershed based on the total area of soil and water loss, the completely treatable area, and the incomplete treatable area.

Here, based on the schematic diagram of the fully controllable area and the incomplete control area of the small watershed, the small watershed area, water and soil loss area, completely controllable area and incomplete control area corresponding to the small watershed are calculated, and based on the small watershed area and water and soil loss area, Calculate the soil and water loss area ratio corresponding to each small watershed.

Step S403: Multiply the area that cannot be completely treated and the treatment rate corresponding to each designated unit area to obtain the updated area that cannot be completely treated.

Here, an incompletely governed area C2 can be divided into multiple designated unit areas. The incompletely governed area is divided according to the designated unit areas. The area of each designated unit area is multiplied by the corresponding governance rate to determine all The sum of the products is the updated incompletely governed area .

Step S404: Sum up the completely treatable area and the updated incompletely treatable area to obtain the treatable area corresponding to each small watershed.

Here, the manageable area .

Step S105: Sort each small watershed according to the preset order standard and treatable area, and obtain the comprehensive treatment priority corresponding to each small watershed in the area to be treated.

Here, the preset sequence criterion can be set to manageable area Standard from large to small. Referring to Table 1, the priority of comprehensive management of the highest-ranking small watershed is determined to be 1, that is, priority management. The smaller the value of the comprehensive governance priority, the higher the corresponding governance priority.
