Description

Technical Field

[0001] The present application relates to the technical field of soil and water loss prevention and control, and in particular to a method and system for preventing and controlling soil and water loss in forestry engineering construction. Background Art

[0002] Soil erosion has brought great harm to our daily life, and the prevention and control of soil erosion has become an important task in my country's ecological construction. Forestry projects such as afforestation can effectively prevent and control soil erosion.

[0003] Current technology can make reasonable planting plans based on regional environmental information in areas with stable environmental information, but it does not take into account areas where environmental information fluctuates greatly. If planting is carried out according to the original strategy, the effect of soil and water loss prevention and control will be significantly reduced. Summary of the invention

[0004] The present application provides a method and system for preventing and controlling soil erosion in forestry engineering construction to solve the above-mentioned problems.

[0005] In a first aspect, the present application provides a method for preventing and controlling soil erosion in forestry engineering construction, the method comprising:

[0006] Acquiring regional information, analyzing the regional information to obtain analysis results, and dividing a number of planting areas according to the analysis results;

[0007] Acquire regional information of the plurality of planting areas, analyze the regional information, and determine soil and water loss information of each planting area;

[0008] Determining plantable tree information according to the regional information and the soil erosion information;

[0009] A planting plan is formulated based on the regional information, the soil erosion information and the plantable tree information for reference by the staff.

[0010] Through the above technical scheme, by dividing a region into multiple planting areas and finely dividing the planting areas in the region, accurate basic information is provided for the subsequent formulation of planting plans. Then, according to the regional information of each region, the soil and water loss change information and the plantable trees are determined, which provides the necessary basic data for the subsequent selection of planted trees in the region, ensuring the accuracy of the selection of planted trees. Then, the trees and planting plans to be planted are selected in combination with the soil and water loss change information and the characteristics of the trees. Through the division of planting areas in the region, the soil and water loss in different planting areas in the region can be scientifically controlled. Different planting trees are selected according to the specific conditions of different regions, and the planting plans are determined in combination with the complex environmental factors within the region, so that the soil and water loss in each region can be more targeted and efficiently controlled. Avoid simply planting a single plant and ignoring the complex factors in the region, which cannot effectively prevent and control the soil and water loss phenomenon in the region, thereby leading to the deterioration of the ecological environment and affecting people's daily life.

[0011] Optionally, dividing a number of planting areas according to the analysis results includes:

[0012] Determining regional environmental information based on the analysis results;

[0013] Determine regional altitude information and regional soil information according to the regional environmental information;

[0014] Determining an environmental change zone according to the altitude information of the region and the soil information of the region;

[0015] According to the environmental change zones, several planting areas are divided.

[0016] Through the above technical solution, starting from the overall environment of the region, the regional altitude information and regional soil information can be determined, which can more accurately understand the agricultural conditions in the region and help to achieve more accurate regional planning. Through the regional altitude information and regional soil information, the environmental change zone can be determined and the planting area can be accurately divided to provide basic information support for subsequent analysis and planting plans, ensuring the accuracy of subsequent planting plans.

[0017] Optionally, the regional altitude information further includes regional altitude information, and the regional soil information further includes soil salinity information and regional soil moisture information, and determining the environmental change zone according to the regional altitude information and the regional soil information includes:

[0018] Analyzing the altitude information of the area to determine the altitude change information between the horizontal displacement and the altitude;

[0019] Analyzing the altitude change information to determine an altitude displacement coupling index;

[0020] Analyzing the soil salinity information to determine soil salinity change information between horizontal displacement and soil salinity;

[0021] Analyzing the soil salinity change information to determine the salinity displacement coupling index;

[0022] Analyzing soil moisture information of the region to determine soil moisture change information between horizontal displacement and soil moisture;

[0023] Analyzing the soil moisture change information to determine a moisture displacement coupling index;

[0024] Determining a soil environment displacement coupling index according to the salinity displacement coupling index and the humidity displacement coupling index;

[0025] An environmental change zone is determined according to the altitude displacement coupling index and the soil environment displacement coupling index.

[0026] Through the above technical solution, by analyzing regional altitude, soil salinity, soil moisture and other information and combining it with horizontal displacement, the solution can provide more refined and multi-dimensional environmental change data. By determining the altitude displacement coupling index, salinity displacement coupling index, and humidity displacement coupling index, the solution realizes the quantitative assessment of environmental changes, making the degree and scope of environmental changes clearer, making the division of environmental change zones more direct and efficient, and facilitating subsequent operations.

[0027] Optionally, determining the plantable tree information according to the area information and the soil erosion information includes:

[0028] Determine regional altitude information and regional soil information according to the regional information;

[0029] Determining the altitude range of the region according to the altitude information of the region;

[0030] Determine the soil salinity and soil moisture within the altitude range of the region according to the regional soil information;

[0031] According to the altitude range of the region, suitable trees within the altitude range of the region are selected;

[0032] According to the soil salinity and humidity, the suitable trees are screened to obtain suitable trees;

[0033] According to the soil and water loss information, the suitable forest trees are screened to determine the plantable forest trees;

[0034] According to the plantable trees, tree information in a preset database is extracted to determine the plantable tree information.

[0035] Through the above technical scheme, according to the altitude information of the planting area, the trees that can be planted within the regional altitude range are preliminarily screened out, and the first step of screening of the trees is carried out, making the subsequent selection more efficient and more purposeful. According to the soil information of the region, the trees that can adapt to the regional soil salinity and soil moisture are further screened out, and the trees are screened by considering the regional environmental information to ensure the survival rate and planting management of the screened trees. Finally, considering the soil erosion situation in the region, the trees that can prevent and control soil erosion in the region are finally screened out. Through the final screening, the trees that can effectively prevent and control soil erosion in the region are selected. Through multiple rounds of screening, the planting trees that perfectly match the altitude, soil environment, and soil erosion situation in the region are determined.

[0036] Optionally, formulating a planting plan according to the regional information, the soil erosion information and the plantable tree information includes:

[0037] Analyze the regional information to obtain analysis results;

[0038] According to the analysis result, determining whether the current area is the environmental change zone;

[0039] If it is not the environmental change zone, determining the trees to be planted and the planting density according to the altitude range of the area, the soil information of the area, the soil erosion information and the information of the trees that can be planted;

[0040] The planted trees and the planting density are determined as a planting plan.

[0041] Through the above technical solution, we first determine whether the current area is an environmental change zone, ensuring that the subsequent operation is based on the planting area. Considering the regional altitude range, soil information, soil erosion information, and plantable tree information, we select the trees to be planted and the planting density. Comprehensive considerations help improve the rationality and feasibility of the planting plan and ensure the planting effect of the trees. Unexpected situations will not occur due to unreasonable dense planting plans, affecting soil erosion prevention and control.

[0042] Optionally, formulating a planting plan according to the regional information, the soil erosion information and the plantable tree information includes:

[0043] If the current area is an environmental change zone, obtaining environmental change zone information;

[0044] Determining the location and range of the environmental change zone according to the environmental change zone information;

[0045] Determining planting information of an area adjacent to the environmental change zone according to the location of the environmental change zone;

[0046] Extracting regional information based on the planting information, and obtaining planted tree information, planting density and regional area based on the regional information;

[0047] Determining whether planting is required according to the range of the environmental change zone and the planting density;

[0048] If planting is required, determine the best tree information for planting based on the environmental change zone information;

[0049] Determine the spacing distance of trees closest to the environmental change zone based on the planting information;

[0050] The planting plan for the environmental change zone is determined based on the spacing distance, the planting density and the optimal planting tree information.

[0051] Through the above technical solution, we first obtain the information of the environmental change zone, and accurately determine the location and range of the environmental change zone, which is the basis for formulating targeted planting plans and ensures the accuracy and effectiveness of subsequent work. Then, based on the planting information of the neighboring areas, we can determine whether the current environmental change zone needs to be planted, avoiding blind planting under unsuitable conditions, thereby saving resources and costs. If planting is required, a reasonable planting plan is formulated by comprehensively considering the spacing distance, planting density and optimal planting forest information, which ensures that planting can meet the needs of the environmental change zone. Through the above methods, the environmental change zone with a complex environment can be effectively managed without affecting the normal planting area.

[0052] Optionally, screening suitable trees for the area and determining trees that can be planted according to the soil erosion information includes:

[0053] determining the degree of soil erosion according to the soil erosion information;

[0054] Determine the priority of treatment according to the degree of soil erosion;

[0055] According to the management priority, plantable trees are selected from the suitable trees.

[0056] Through the above technical scheme, the priority of managing water loss and soil loss can be divided according to the degree of water loss and soil loss, so that trees can be selected in a targeted manner, and the management of the two will be more focused, making the prevention and control of soil and water loss in the current planting area more effective.

[0057] Optionally, determining the control priority according to the degree of soil erosion includes:

[0058] Determine the rainfall information, slope length and slope information, soil type information, and vegetation coverage information of the region according to the regional information;

[0059] Determining a rainfall factor according to the rainfall information;

[0060] Determine the terrain slope factor and the slope length and slope factor according to the slope length and slope information;

[0069] The management priority is determined according to the water loss degree index and the soil loss degree index.

[0070] Through the above technical solution, various parameter indicators that affect soil erosion are obtained from the region, and comprehensive consideration of multiple parameters can more accurately reflect the soil erosion situation, and by quantifying various data, the evaluation results are more intuitive and comparable. And according to the water loss degree index formula and the soil loss degree index, the governance priority is obtained, which is helpful to reasonably allocate governance resources and carry out targeted governance of soil erosion, which is more suitable for the soil erosion situation in the region.

[0071] Optionally, determining the governance priority according to the water loss degree index and the soil loss degree index includes:

[0072] Subtracting the water loss degree index from the soil loss degree index to obtain a numerical difference between the water loss degree and the soil loss degree;

[0073] Compare the numerical difference with a threshold value, and determine whether the numerical difference is greater than the threshold value according to the comparison result;

[0074] If the numerical difference is greater than a threshold, the water loss degree index is compared with the soil loss degree index to obtain a comparison result;

[0075] Determine governance priorities based on the comparison results.

[0076] Through the above technical solution, the absolute value is obtained by subtracting the water loss degree index from the soil loss degree index and comparing it with the threshold value. The management priority is determined according to the comparison result, and the management priority is clearly known through mathematical calculation.

[0144] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0145] In addition, the term "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article, unless otherwise specified, generally means that the associated objects before and after are in an "or" relationship.

[0146] The embodiments of the present application are further described in detail below in conjunction with the drawings in the specification.

[0147] In order to control soil erosion, forestry often uses afforestation to improve soil erosion. By considering the environmental information of different regions and choosing suitable trees to plant, soil erosion in a certain area can be controlled in a targeted manner, making the control effect more significant. However, in some areas, the environment fluctuates greatly, and insufficient consideration is given to environmental changes, and a single tree is chosen for planting, resulting in poor control effects or even no control.

[0148] Based on this, the present application provides a method and system for preventing and controlling soil erosion in forestry engineering construction. According to regional information, the region is divided into several planting areas, and then according to the planting area information, the environmental information and soil erosion information in the planting area are determined, and the information of plantable trees is determined by combining the two. Finally, according to the regional information, the degree of soil erosion in the region and the information of plantable trees, the final planting plan is determined. By dividing the region into multiple planting areas according to environmental changes, a planting plan is formulated according to the actual conditions in each area, so as to avoid the single choice of planting trees that may not be completely suitable for the current environment, thereby affecting the prevention and control effect.

[0149] Figure 1 A schematic diagram of an application scenario provided for this application. In a forestry engineering construction scenario, the method provided by this application is applied to divide the planting areas according to the local environment and formulate planting plans suitable for each area.

[0150] Specifically, the method provided in the present application is applied to any server, and the server interacts with the regional information management system.

[0151] The server obtains regional information from the regional information management system and analyzes it, divides it into several planting areas based on the analysis results, and then analyzes the planting areas to obtain soil and water loss information in the area. It then uses the soil and water loss information in combination with the regional environment to determine the information of planted trees. It then further analyzes the soil and water loss information in the area and formulates a regional planting plan for the staff to refer to, so that different planting plans can be customized according to different environments to avoid a single planting plan in the region, where the selected trees are not suitable for the planting environment, affecting the effect of soil and water loss prevention and control.

[0152] For specific implementation methods, please refer to the following embodiments.

[0153] Figure 2 This is a flow chart of a method for preventing and controlling soil erosion in forestry engineering construction provided in one embodiment of the present application. The method of this embodiment can be applied to the server in the above scenario. Figure 2 As shown, the method includes:

[0154] S201, acquiring regional information, analyzing the regional information, obtaining analysis results, and dividing a number of planting areas according to the analysis results.

[0155] The regional information may be the regional information where the forestry project construction is being carried out, and the regional information may include regional altitude, regional soil, regional soil erosion conditions, regional location, and the like.

[0156] The planting area can be an area divided according to environmental differences within a region, and the planting area is divided according to regional information.

[0157] Specifically, first obtain regional information, use statistical methods to analyze, get analysis results, determine the environmental information in the region from the analysis results, and when there are certain environmental differences between two areas in the region, divide the two areas into two different planting areas.

[0158] S202: Acquire regional information of several planting areas, analyze the regional information, and determine soil and water loss information of each planting area.

[0159] The regional information may be environmental information within the planting area, and the regional information includes regional altitude, regional geology, regional location, etc.

[0160] Soil and water loss information may be the phenomenon that due to natural or human factors, rainwater in the planting area cannot be absorbed locally, flows downstream, and washes the soil, causing the loss of both water and soil.

[0161] Specifically, the soil condition and runoff information of the planting area are obtained, and the soil condition and runoff information of the planting area are analyzed using mathematical methods to determine the soil and water loss information in the area.

[0162] S203: Determine plantable tree information based on regional information and soil erosion information.

[0163] The plantable tree information may be all tree information that can adapt to the environment and soil erosion conditions of the planting area. The plantable tree information includes growth cycle, suitable planting density, etc.

[0164] Specifically, based on regional information, the regional environment is obtained through natural language processing technology, and all forest information is obtained through a third-party platform. Then, based on all forest information, trees that can adapt to the regional environment are screened, and then the soil and water erosion conditions in the region are matched to screen out trees that can adapt to the regional environment and improve the regional soil and water erosion conditions. All trees that meet the conditions are determined as plantable trees, and the plantable tree information is obtained.

[0165] S204. Develop a planting plan based on regional information, soil erosion information, and plantable tree information for reference by staff.

[0166] A planting plan may be a plan that focuses on what trees to plant and how to plant them in a planting area. A planting plan includes the trees to be planted, the planting density, etc.

[0167] Specifically, after an in-depth analysis of soil and water loss information, the planted trees are ranked in terms of their effect on improving soil and water loss. Based on the ranking results, trees that are more suitable for the soil and water loss situation in the current planting area are selected from the planted trees. Based on this tree and regional information, it is determined how to densely plant the trees in the area. By ultimately selecting the planted trees, the characteristics of the trees are highly matched to the soil and water loss situation in the planting area, thereby maximizing the prevention and control effect.

[0168] Through the method provided in this embodiment, by dividing a region into multiple planting areas and finely dividing the planting areas in the region, accurate basic information is provided for the subsequent formulation of planting plans. Then, based on the regional information of each region, the soil and water loss change information and the plantable trees are determined, which provides the necessary basic data for the subsequent selection of planted trees in the region, ensuring the accuracy of the selection of planted trees. Then, the trees and planting plans to be planted are selected in combination with the soil and water loss change information and the characteristics of the trees. Through the division of planting areas in the region, the soil and water loss in different planting areas in the region can be scientifically controlled. Different planting trees are selected according to the specific conditions of different regions, and the planting plan is determined in combination with the complex environmental factors within the region, so that the soil and water loss situation in each region can be more targeted and efficiently controlled. Avoid simply planting a single plant and ignoring the complex factors in the region, which cannot effectively prevent and control the soil and water loss phenomenon in the region, thereby leading to the deterioration of the ecological environment and affecting people's daily life.

[0169] In some embodiments, regional environmental information is determined based on the analysis results; regional altitude information and regional soil information are determined based on the regional environmental information; environmental change zones are determined based on the regional altitude information and regional soil information; and several planting areas are divided based on the environmental change zones.

[0170] The regional environmental information may be the environmental information of the region where the planting area is divided this time.

[0171] The regional altitude information may be the altitude information of the region where the planting area is divided this time.

[0172] The regional soil information may be the soil information of the region where the planting area is divided this time.

[0173] The environmental change zone can be the connecting area between two planting areas in a region. In the environmental change zone, the environment has undergone significant changes, thus dividing two different planting areas. The range of the environmental change zone is usually small and may not be as long and wide as reflected by the unit planting density of the planting area.

[0174] Specifically, the environmental information of the region is obtained from the regional analysis results, and the altitude information and soil information of the region are obtained based on the regional environmental information.

[0175] When the altitude in an area changes suddenly and significantly, such as from the original flat land to a 30-degree slope; or the soil conditions in the area change significantly, such as the pH suddenly changes from 9 to 8; an index for evaluating altitude changes and an index for evaluating soil condition changes are constructed through mathematical means. The change in the index can be determined based on the change in altitude and soil conditions. The areas where the index changes significantly are identified as environmental change zones, and the areas surrounding the environmental change zones are different planting areas.

[0176] Through the method provided in this embodiment, starting from the overall environment of the region, the regional altitude information and regional soil information are determined, which can more accurately understand the agricultural conditions in the region, help to achieve more accurate regional planning, and determine the environmental change zones through regional altitude information and regional soil information. Accurate division of planting areas provides basic information support for subsequent analysis and planting plans, ensuring the accuracy of subsequent planting plans.

[0177] In some embodiments, the regional altitude information is analyzed to determine the altitude change information between the horizontal displacement and the altitude; the altitude change information is analyzed to determine the altitude displacement coupling index; the soil salinity information is analyzed to determine the soil salinity change information between the horizontal displacement and the soil salinity; the soil salinity change information is analyzed to determine the salinity displacement coupling index; the regional soil moisture information is analyzed to determine the soil moisture change information between the horizontal displacement and the soil moisture; the soil moisture change information is analyzed to determine the moisture displacement coupling index; based on the salinity displacement coupling index and the humidity displacement coupling index, the soil environment displacement coupling index is determined; based on the altitude displacement coupling index and the soil environment displacement coupling index, the environmental change zone is determined.

[0178] The altitude change information may be information about how the altitude in a region changes as the spatial position changes.

[0179] The elevation-displacement coupling index can be an index used to quantify the interaction relationship between elevation and horizontal displacement.

[0180] The soil salinity change information may be information on how the soil salinity in a region changes with the spatial position.

[0181] The salinity-displacement coupling index can be an index used to quantify the interaction relationship between horizontal displacement and soil salinity.

[0182] The soil moisture change information may be information on how the soil moisture in a region changes as the spatial position changes.

[0183] The moisture-displacement coupling index can be an index used to quantify the interaction relationship between horizontal displacement and soil moisture.

[0184] The soil environment displacement coupling index can be an index derived from the salinity displacement coupling index and the moisture displacement coupling index, and is used to quantify the interaction between the soil environment (including salinity and moisture) and displacement.

[0185] Specifically, the altitude information in the area is analyzed to obtain the altitude data in the area, and the altitude data of the area is processed using software, such as GIS (Geographic Information System) software, to determine the direction and amplitude of the horizontal displacement, and the altitude and horizontal displacement data are spatially superimposed to calculate the change in altitude when the horizontal displacement is displaced in the determined direction and amplitude, and the change in altitude is divided by the change in horizontal displacement to obtain the altitude displacement coupling index. For example, if the horizontal displacement standard is 10 cm, that is, the coupling index is calculated every 10 cm, when the horizontal displacement changes by 10 cm, the altitude changes by 10 cm, then the altitude displacement coupling index is 10 / 10, and the result is 1.

[0186] The soil conditions in the area (including soil salinity and soil moisture) were analyzed. First, the soil salinity was quantified as a percentage of salt content, and the soil moisture was quantified as the percentage of soil water weight to its dry soil weight. The values ​​of soil salinity and soil moisture were also spatially superimposed with the horizontal displacement data. The changes in soil salinity and soil moisture when the horizontal displacement changed in a certain direction and amplitude were calculated. The changes in soil salinity and soil moisture were divided by the changes in horizontal displacement to obtain the salinity-displacement coupling index and the moisture-displacement coupling index. If the horizontal displacement standard is still 10 cm, and the soil salinity and soil moisture have changed by 1% and 5% respectively, then the salinity-displacement coupling index and the moisture-displacement coupling index are 0.1% / cm and 0.5% / cm respectively.

[0187] The soil environment displacement coupling index is obtained by weighted calculation of the salinity displacement coupling index and the humidity displacement coupling index. The weights may vary according to regional conditions. The altitude displacement coupling index and the soil environment displacement coupling index are analyzed. When a certain index changes dramatically, the area where the index data is obtained is considered to be an environmental change zone, or when a certain index has multiple consecutive changes of the same type, when the cumulative change exceeds the threshold, the last change area is determined to be an environmental change zone.

[0188] Through the method provided in this embodiment, by analyzing information such as regional altitude, soil salinity, soil moisture, and combining it with horizontal displacement, the solution can provide more refined and multi-dimensional environmental change data. By determining the altitude displacement coupling index, the salinity displacement coupling index, and the humidity displacement coupling index, the solution realizes a quantitative assessment of environmental changes, making the degree and scope of environmental changes clearer, making the division of environmental change zones more direct and efficient, and facilitating subsequent operations.

[0189] In some embodiments, regional altitude information and regional soil information are determined based on regional information; regional altitude range is determined based on regional altitude information; soil salinity and soil moisture within the regional altitude range are determined based on regional soil information; suitable trees within the regional altitude range are screened out based on the regional altitude range; suitable trees are screened based on soil salinity and moisture to obtain suitable trees; suitable trees are screened based on soil and water loss information to determine plantable trees; based on plantable trees, tree information in a preset database is extracted to determine plantable tree information.

[0190] Suitable forests can be planted trees that are suitable for the altitude range of the current area, and there can be many types of suitable forests.

[0191] Adaptive forests can be planted trees that are selected from suitable forests and can adapt to the salinity and humidity of the current area. There can be many types of planted trees.

[0192] Plantable trees can be those selected from suitable trees in the area that can effectively control soil and water loss in the current area.

[0193] Specifically, the altitude information and soil information of the region are obtained from the regional information through natural language processing technology, the altitude range in the region is determined based on the altitude information, and the soil salinity and soil moisture in the region are determined based on the soil information.

[0194] In order to select trees that can be planted, we first select trees that are suitable for planting within the altitude range, that is, suitable trees. Then, based on the soil salinity and humidity, we consider the salt-alkali and drought resistance of suitable trees, and select trees that can be planted in the soil environment of the current region, that is, suitable trees. Finally, based on the soil and water loss situation, we consider the soil-fixing and water-holding capacity of suitable trees, and select trees that can control soil and water loss in the current region, and determine them as trees that can be planted.

[0195] Through the method provided in this embodiment, based on the altitude information of the planting area, the trees that can be planted within the regional altitude range are preliminarily screened out, and the first step of screening of the trees is performed to make the subsequent selection more efficient and more purposeful. Based on the soil information of the region, the trees that can adapt to the regional soil salinity and soil moisture are further screened out, and the trees are screened by considering the environmental information of the region to ensure the survival rate and planting management of the screened trees. Finally, considering the soil and water loss situation in the region, the trees that can prevent and control soil and water loss in the region are finally screened out. Through the final screening, the trees that can effectively prevent and control soil and water loss in the region are selected. Through multiple rounds of screening, the planted trees that perfectly match the altitude, soil environment, and soil and water loss situation in the region are determined.

[0196] In some embodiments, regional information is analyzed to obtain analysis results; based on the analysis results, it is determined whether the current area is an environmental change zone; if it is not an environmental change zone, the trees to be planted and the planting density are determined based on the regional altitude range, regional soil information, soil erosion information and plantable tree information; the planted trees and planting density are determined as a planting plan.

[0197] The planting density may be the planting density of the planted trees selected in the current area that is planned based on the actual situation in the area, and may be different from the recommended planting density in the tree information of the planted trees.

[0198] Specifically, the regional information is first analyzed to obtain the analysis results, and the current regional type is obtained from the analysis results. It is determined whether it is an environmental change zone based on the regional type. When the area is not an environmental change zone, planting planning is carried out. According to the information of plantable trees, the growth cycles of plantable trees are sorted, and trees with the shortest growth cycle are selected as planted trees. Combined with the soil and water erosion situation in the current area, it is determined whether the soil and water erosion situation in the current area can be met based on the amount of water and soil resources required for planting trees. If not, the actual planting density is calculated through mathematical calculations for planting. If it can be met, planting is carried out according to the planting density determined by the characteristics of the trees themselves.

[0199] Through the method provided in this embodiment, it is first determined whether the current area is an environmental change zone, ensuring that the subsequent operation basis is the planting area. Considering the regional altitude range, soil information, soil erosion information, and plantable tree information to select planted trees and planting density, comprehensive consideration helps to improve the rationality and feasibility of the planting plan, and ensures the planting effect of the trees, and will not cause unexpected forest conditions due to unreasonable dense planting plans, affecting soil erosion prevention and control.

[0200] In some embodiments, if the current area is an environmental change zone, obtain the environmental change zone information; determine the location and range of the environmental change zone based on the environmental change zone information; determine the planting information of the adjacent area of ​​the environmental change zone based on the location of the environmental change zone; extract the regional information based on the planting information, and obtain the planted tree information, planting density and regional area based on the regional information; determine whether planting is needed based on the range and planting density of the environmental change zone; if planting is needed, determine the best planting tree information based on the environmental change zone information; determine the interval distance of the trees closest to the environmental change zone based on the planting information; determine the planting plan for the environmental change zone based on the interval distance, planting density and the best planting tree information.

[0201] The optimal forest planting information may be the forest planting information most suitable for the area with environmental change zones.

[0202] Specifically, first obtain the environmental change zone information to determine the environmental change location and the range of the environmental change zone. According to the location of the environmental change zone, it is possible to obtain the neighboring planting areas and extract the planting information of these planting areas. From the planting information, extract what kind of trees are planted in the planting area, what the planting density is, and how large the area is. Calculate the distance from the edge of the area to the outermost layer of trees planted in the current planting area from the area and the planting density. This distance can be considered as the distance to the environmental change zone, that is, the spacing distance. If the spacing distance of each planting area is greater than the spacing distance between the trees planted in the planting area, the environmental change zone needs to be planted. If there is a planting area with a spacing distance less than the spacing distance between the trees planted in the planting area, it is considered that the soil and water loss prevention and control of the current environmental change zone has been prevented and controlled by the neighboring planting areas. Select suitable trees based on the soil information and altitude information of the environmental change zone, calculate which location will not affect each other based on the tree information and the spacing distance, and use the selected trees and the calculated planting location as the planting plan for the environmental change zone.

[0203] Through the method provided in this embodiment, the environmental change zone information is first obtained to accurately determine the location and range of the environmental change zone, which is the basis for formulating targeted planting plans and ensures the accuracy and effectiveness of subsequent work. Then, based on the planting information of the adjacent areas, it is determined whether the current environmental change zone needs to be planted, avoiding blind planting under unsuitable conditions, thereby saving resources and costs. If planting is required, a reasonable planting plan is formulated by comprehensively considering the spacing distance, planting density and optimal planting forest information, which ensures that planting can meet the needs of the environmental change zone. Through the above method, the environmental change zone with a complex environment can be effectively managed without affecting the normal planting area.

[0204] In some embodiments, the degree of soil erosion is determined based on soil erosion information; the management priority is determined based on the degree of soil erosion; and plantable trees are selected from suitable trees based on the management priority.

[0205] The control priority can be the emphasis on controlling the degree of water loss and soil erosion in the planting area.

[0206] Specifically, based on the soil and water loss information, the water loss and soil loss conditions in the soil and water loss are obtained, and based on the water loss and soil loss conditions, the water loss degree and the soil loss degree are determined. The water loss degree and the soil loss degree are compared, and the management priorities are divided. Based on the management priorities, trees with a focus on water loss management or soil loss management are selected as planting trees. Through such operations, soil and water loss prevention and control in the planting area is more targeted.

[0207] Through the method provided in this embodiment, the control priorities of water loss and soil loss are divided according to the degree of the two, so that trees can be selected in a targeted manner, and the control of the two will be more focused, making the prevention and control of soil and water loss in the current planting area more effective.

[0208] In some embodiments, based on the regional information, the rainfall information, slope length and slope information, soil information, and vegetation coverage information of the region are determined; based on the rainfall information, the rainfall factor is determined; based on the slope length and slope information, the terrain slope factor and the slope length and slope factor are determined; based on the soil information, the soil type factor and the soil erodibility factor are determined; based on the vegetation coverage information, the vegetation coverage factor is determined; based on the rainfall factor, the terrain slope factor, the soil type factor, and the vegetation coverage factor, the water loss degree index is determined; based on the rainfall factor, the soil erodibility factor, the slope length and slope factor, and the vegetation coverage factor, the soil loss degree index is determined; based on the water loss degree index and the soil loss degree index, the governance priority is determined.

[0209] The water loss degree index is determined based on the rainfall factor, terrain slope factor, soil type factor and vegetation cover factor. The water loss degree index is determined by referring to formula (1):

[0210] (1)

[0211] in, Indicates the water loss index. represents the rainfall factor, represents the terrain slope factor, represents the soil type factor, Represents the vegetation cover factor.

[0212] The soil loss degree index is determined based on the rainfall factor, soil erodibility factor, slope length and slope factor, and vegetation coverage factor. The soil loss degree index is determined by referring to formula (2):

[0213] (2)

[0214] in, It represents the soil loss degree index. represents the rainfall factor, represents the soil erodibility factor, represents the slope length and slope factor, Represents the vegetation cover factor.

[0215] The rainfall factor may be a factor reflecting the effect of rainfall on water loss in a region. The greater the rainfall, the more water loss and the greater the rainfall factor.

[0216] The terrain slope factor can be a factor that reflects the impact of the slope in the area on water loss. The greater the slope, the more water loss, and the greater the terrain slope.

[0217] The slope length and slope factor can be a factor that reflects the degree of soil erosion in a region. The slope length refers to the horizontal projection distance between the starting point of surface runoff on the slope and the silt accumulation point or ditch along the direction of maximum slope drop.

[0218] The soil type factor may be a factor that reflects the different sensitivities of different soil types to water loss. For example, sandy soil and clay soil have different sensitivities to water loss, and thus have different soil type factors.

[0219] The soil erodibility factor can be a factor that reflects the sensitivity of soil properties to erosion. It characterizes the ease with which soil particles are separated, transported, and deposited under the action of external forces such as rainfall and runoff.

[0220] The vegetation cover factor may be a factor representing the impact of vegetation cover on soil erosion. The higher the vegetation cover, the smaller the vegetation cover factor.

[0221] Specifically, rainfall information, slope length and slope information, soil information, and vegetation coverage information are extracted from regional information through natural language processing technology. A certain time period is selected from the current time. According to the rainfall during this period and the rainfall area coverage rate, the rainfall and rainfall area coverage rate are multiplied to obtain the rainfall factor. Then, according to the slope length and slope information, the angle between the horizontal direction of the slope and the slope surface is determined, and the value of the angle is determined as the terrain slope factor. After the terrain slope factor is obtained, there will be different slope length functions according to the slope value and the slope length value. For example, when the slope length and slope are linearly related, a linear function can be used to describe it. The slope length factor is obtained using the slope length and slope data as parameters, and the slope length factor is multiplied by the terrain slope factor to obtain the slope length and slope factor. According to soil information, the soil type is determined. The soil type factor can be queried through online query. In addition to soil type, the soil erodibility factor also needs to consider soil texture, organic matter content, and soil structure. According to soil texture, organic matter content, and soil structure, the soil erodibility factor can be calculated. Existing algorithms, such as the algorithm in the EPIC model, can be used. Then, the vegetation coverage rate is obtained according to the vegetation coverage information. The vegetation coverage rate is used as the value of the vegetation coverage factor. After all the above parameters are obtained, the water loss degree and soil loss degree are calculated according to formula (1) and formula (2) respectively. Then, by comparing the two, the comparison result is obtained to determine whether there is a priority division between the two. If there is, the one with the larger value is determined as the high priority for governance. In this way, the abstract degree of water and soil erosion is concretely converted into a numerical form, and the degree of the two is directly and clearly judged, providing an accurate judgment basis for governance priority.

[0222] Through the method provided by this embodiment, various parameter indicators that affect soil erosion are obtained from the region, and multiple parameters are comprehensively considered to more accurately reflect the soil erosion situation, and by quantifying various data, the evaluation results are more intuitive and comparable. And according to the water loss degree index formula and the soil loss degree index, the governance priority is obtained, which is helpful to reasonably allocate governance resources, carry out targeted governance of soil erosion, and be more suitable for the soil erosion situation in the region.

[0223] In some embodiments, the water loss degree index is subtracted from the soil loss degree index to obtain a numerical difference between the water loss degree and the soil loss degree; if the numerical difference is greater than a threshold, the water loss degree index is compared with the soil loss degree index to obtain a comparison result; based on the comparison result, the governance priority is determined.

[0224] The threshold value can be the maximum value of the difference between the allowable water loss index and the soil loss index formulated according to the soil and water loss conditions in the current planting area. The threshold value can be obtained by the average of the water loss index and the soil loss index according to a certain ratio. When the threshold value is exceeded, it means that the soil and water loss situation in the area is unbalanced and targeted governance is needed.

[0225] Specifically, the water loss index is subtracted from the soil loss index to obtain the difference, and the absolute value of the difference is taken as the numerical difference, and the numerical difference is compared with the threshold. When the numerical difference is not greater than the threshold, it can be considered that the two have the same management priority. If the numerical difference is greater than the threshold, the water loss index is compared with the soil loss index, and the larger one is determined as a high management priority, and more targeted trees are selected when selecting trees.

[0226] Through the method provided in this embodiment, the absolute value obtained by subtracting the water loss degree index from the soil loss degree index is compared with the threshold, the management priority is determined according to the comparison result, and the management priority is clearly known through mathematical calculation.
