Description

Technical Field

[0001] The present invention belongs to the technical field of power systems, and particularly relates to a method and device for repairing soil disturbance in a power transmission and transformation project based on regional division. Background Art

[0002] The construction and use of power transmission and transformation projects will have various impacts on the soil. During the construction phase, the project requires a large amount of land occupation, surface excavation, and equipment installation, which will lead to the destruction of the soil structure and the removal of surface vegetation, thus changing the physical properties of the soil, such as soil density and permeability. Heavy machinery and vehicles used during the construction process will compact the soil, reduce the soil porosity, and affect the ventilation and drainage capabilities of the soil. During the use phase of the power transmission and transformation project, the electromagnetic radiation and thermal effects generated by the operation of the equipment may affect the microbial community and chemical composition in the soil, thereby affecting the soil fertility and ecological balance. In addition, the long-term existence of power transmission and transformation facilities may also lead to soil salinization or acidification, affecting the growth of surrounding plants and the sustainable utilization of the soil.

[0003] Currently, during the construction phase, temporary retaining measures will be implemented, such as using woven bags or grass bags filled with soil or sand to temporarily block around the construction area to control soil erosion and atmospheric dust. During the use phase of the power transmission and transformation project, mostly soil data detection is carried out on-site, and the detected soil data is recorded and summarized. According to the results of the record summary, the soil conditions are determined, and information such as the types of plants and plant densities required for soil repair are determined according to the soil conditions.

[0004] However, this method requires a large amount of manpower and material resources, and due to the large coverage area of the power transmission and transformation project, it is difficult to comprehensively collect the soil information affected by the power transmission and transformation project and accurately repair the key areas. Summary of the Invention

[0024] In the following description, specific details such as specific system structures and technologies are proposed for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present invention. However, those skilled in the art should clearly understand that the present invention can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details from interfering with the description of the present invention.

[0025] Figure 1 is a schematic flowchart of a method for repairing soil disturbance in a power transmission and transformation project based on area division provided by an embodiment of the present invention. Referring to Figure 1 , the details of this method are as follows:

[0026] S110. Obtain the construction information of the target power transmission and transformation project, and determine the project characteristics and disturbed areas of the target power transmission and transformation project based on the construction information.

[0027] In some embodiments, the construction information is an important basis for the soil disturbance restoration of the power transmission and transformation project, covering multiple links from preliminary planning to on-site investigation. The construction information mainly includes specific information such as the total construction length, project links, construction stages, influence duration, and disturbed areas.

[0028] In some embodiments, determining the project characteristics based on the construction information requires comprehensive consideration in all aspects. The total construction length reflects the project scale. A long and complex line indicates a wide project coverage, high construction difficulty, and complex soil disturbance, from which the project scale level characteristics can be determined. The project links show the construction complexity. The unique requirements of different links determine the construction process difficulty, and then the construction process characteristics can be summarized. The time node distribution and influence duration of the construction stage respectively affect the dynamic law of soil disturbance and the recovery time. Based on this, the characteristics of the project in the time dimension can be clarified, including the disturbance type and influence duration type.

[0029] Among them, through the comprehensive analysis of the construction information in multiple dimensions such as scale, construction process, time, and region, the project characteristics can be accurately refined. These characteristics cover aspects such as the project scale size, construction process difficulty, time law of soil disturbance, and regional influence characteristics.

[0030] In this embodiment, determining the scope of the disturbed area helps to clarify the regional influence characteristics of the project. If the scope of the disturbed area is large and spans multiple ecological function areas, the ecological impact range of the project is more extensive, and different requirements for soil restoration in different ecological function areas need to be considered. For example, for the part of the disturbed area involving the farmland protection area, soil restoration needs to give priority to the impact on crop growth and ensure the restoration of soil fertility; while for the part involving the nature reserve, more attention should be paid to the protection of the integrity of the ecosystem. By analyzing the scope of the disturbed area, the regional characteristics of the project can be described as cross-regional composite or single-region type projects, providing a regional basis for subsequent soil disturbance restoration for different regions.

[0031] The accurate determination of the project characteristics lays a solid foundation for the subsequent soil disturbance restoration work of the power transmission and transformation project, helps to fully consider the characteristics of the project itself in the aspects of regional division, restoration plan formulation, etc., makes the restoration measures more targeted and effective, and ensures the coordinated development of the power transmission and transformation project and the soil ecosystem on the premise of protecting the ecological environment.

[0032] S120. Divide the disturbed area into multiple regions based on the project characteristics, collect the regional characteristics of each region, and determine the sensitive areas based on the regional characteristics.

[0033] In a possible implementation, the specific processing procedure of step S120 is as follows: Based on engineering features, determine the total construction length of the target power transmission and transformation project, and divide the disturbed area into multiple initial regions based on the construction length; collect the regional features of each initial region, and based on the initial region features, determine the initial region area and the regional environmental information of the initial region; based on the initial region areas and regional environmental information of all initial regions, adjust each initial region to obtain multiple regions.

[0034] In some embodiments, when dividing the initial regions, it can be divided at a certain length interval, or the total construction length can be reasonably segmented in combination with the convenience of engineering construction and the geographical characteristics of the region to form multiple relatively independent initial regions, laying a foundation for subsequent refined analysis and processing.

[0035] For example, as Figure 2 shown, the target power transmission and transformation project is a transmission line with a total length of 50 kilometers, and its disturbed area is distributed in a strip along the line direction. According to the engineering features and actual situation, it is determined that the disturbed area is divided into initial regions at a length interval of every 5 kilometers. In this way, starting from the starting point of the line, 0 - 5 kilometers is the first initial region, 5 - 10 kilometers is the second initial region, and so on, a total of 10 initial regions can be divided.

[0036] For example, a circular area with a radius of 2 kilometers centered on the substation is the main disturbed area. Divide the circumference of this circular area (according to the formula for the circumference of a circle, the circumference is approximately 12.56 kilometers) at an interval of every 2 kilometers. Specifically, starting from the due east direction of the substation, the arc length range of 0 - 2 kilometers is the first initial region, the arc length range of 2 - 4 kilometers is the second initial region, and so on, approximately 6 initial regions can be divided. During actual division, in combination with the azimuth angle and distance measurement on the circumference, accurately determine the boundaries of each initial region.

[0037] In this embodiment, after the initial region division is completed, various methods can be comprehensively used to collect regional features. For example, through on-site investigation and sampling, collect soil samples according to rules to analyze their physical, chemical, and biological properties, use measuring instruments to obtain topographic and geomorphic features, and observe vegetation coverage features; environmental monitoring and data analysis can be carried out, collect meteorological data and evaluate the surrounding environmental impact; historical data can also be consulted to understand land use and soil evolution, and expert experience can be used for judgment.

[0038] In some embodiments, the regional environmental information includes the physical, chemical, and biological properties of each specific location within the region.

[0039] When the area of the initial region is too large and there are significant differences in internal characteristics, it can be subdivided according to soil type, topography, etc. to make the characteristics within the region more homogeneous for precise restoration of soil disturbance. Additionally, special environments need to be considered. For example, parts in ecologically fragile areas or near water sources should be separately demarcated, and restoration strategies tailored to their requirements should be formulated. When area and environmental factors are intertwined, it is necessary to demarcate based on the boundaries of ecological function areas, etc., and at the same time take into account differences in soil fertility in different regions to formulate corresponding restoration measures, thus ensuring the scientific nature and effectiveness of the restoration work.

[0040] It should be noted that after adjustment, the interior of the region is more similar in soil properties and similar in topography, which provides convenience for formulating unified and precise restoration measures. The vegetation cover and ecological functions are unified, and the ecological sensitivity and protection needs are clear, facilitating the implementation of targeted restoration work around it, protecting ecological balance and security. The area is appropriate, which is conducive to resource allocation, construction operations, and effect monitoring and evaluation, making the restoration measures highly operable and contributing to the orderly restoration of the soil ecosystem in the disturbed area.

[0041] Dividing the initial region based on engineering characteristics can reasonably divide the disturbed area according to the actual situation of the power transmission and transformation project, clarify the spatial distribution of soil disturbance, and provide a geographical framework for restoration. By collecting regional characteristics, the natural conditions can be comprehensively grasped. Area measurement provides a basis for resource allocation, etc., and environmental information helps analyze the disturbance situation. Adjusting the region according to area and environmental information can formulate restoration measures for different conditions, avoid secondary damage to special regions, improve the restoration efficiency and effect, make the restoration work more orderly and efficient, and facilitate monitoring and evaluation to achieve the stable restoration of the soil ecosystem.

[0042] In a possible implementation manner, the specific processing process of step S120 is as follows: Extract the soil characteristics of each region from the soil database and determine the soil characteristics as the initial region characteristics of the corresponding region; conduct image acquisition for each region, and based on the image acquisition results, adjust the initial region characteristics to obtain the region characteristics of the corresponding region; for each region, based on the region characteristics of the region, determine the integrity and priority of the region, and determine the regions with integrity not higher than the preset value or priorities exceeding the preset priority as sensitive regions.

[0043] In some embodiments, the soil database can be obtained from the soil survey results of government departments and research institutions, or can be obtained by accumulating and integrating historical soil monitoring data. Long-term established soil monitoring stations continuously collect soil-related data, which not only form the soil database but also can reflect soil changes.

[0044] In some embodiments, the soil characteristics mainly include the soil area, soil vegetation coverage information, the properties of the soil, and the results of topographic and geomorphic zoning. Among them, the properties of the soil include physical properties (such as soil texture, structure, porosity, etc.), chemical properties (such as pH value, nutrient content, heavy metal content, etc.), and biological properties (such as microbial community structure, enzyme activity, etc.).

[0045] In some embodiments, the initial regional characteristics can be adjusted based on the image acquisition results. For soil texture, it can be adjusted by analyzing the image color and texture features, such as sandy soil having a light color and rough texture, and clay having a dark color and fine texture, and then comparing and rechecking with on-site sampling. For soil humidity, it can be corrected based on spectral reflection characteristics and the analysis of color and light and dark changes, in combination with image data at different times, on-site humidity measurements, meteorological data, etc. At the same time, based on the image acquisition results, the results of topographic and geomorphic zoning in the initial regional characteristics can be adjusted.

[0046] Among them, the integrity is obtained by comparing the regional characteristics after the establishment of the power transmission and transformation project with the characteristics before the establishment of the power transmission and transformation project. For example, a comprehensive evaluation index can be obtained from the regional characteristics, and this comprehensive evaluation index can be compared with the comprehensive evaluation index of this region before the establishment of the power transmission and transformation project to obtain the integrity of this region.

[0047] In some embodiments, when evaluating the regional priority, aspects such as vegetation coverage rate, soil physical properties, soil chemical properties, and soil biological properties need to be comprehensively considered. The specific determination method is not limited here. For example, the weights of each aspect can be determined according to the needs of different regions, and then the priority can be calculated based on the specific values. The regional priority is mainly used to reflect the urgency of restoration of this region.

[0048] In some embodiments, the sensitive area is the area that needs to be repaired with emphasis. The sensitive area is jointly determined by the integrity and the priority. For example, if the preset integrity is 50%, and the integrity of area 1 is 46%, then area 1 can be determined as a sensitive area; for another example, if the preset priority is level 3, and the priority of area 2 is level 4, then area 2 can be determined as a sensitive area; however, if the preset integrity is 50%, the preset priority is level 3, the integrity of area 3 is 60%, and the priority is level 2, then area 3 is not a sensitive area.

[0049] S130. For each sensitive area, based on the regional characteristics of this sensitive area, construct a simulation model of this sensitive area, and based on the simulation model, determine the disturbance information of this sensitive area.

[0050] It should be noted that before constructing the simulation model, it is necessary to first determine the key points to be repaired in the sensitive area according to the regional characteristics of the sensitive area, and then further determine the type of the simulation model. If the structure and function evolution of the ecosystem in the area to be repaired are concerned, an ecosystem model needs to be selected, such as a process-based ecological model (such as the BIOME-BGC model) or a niche model (such as the MaxEnt model); if the hydrological processes in the concerned area are focused on, such as rainfall-runoff relationship, groundwater flow, etc., a hydrological model is selected, such as the SWAT model or the MODFLOW model; if the soil erosion process in the area is to be simulated, a soil erosion model can be selected, such as the USLE model or the RUSLE model, etc.

[0051] In some embodiments, when obtaining the disturbance information, it is necessary to first clearly define the disturbance type and parameterize it. For example, corresponding parameters are determined for land occupation, vegetation clearing, chemical pollution, etc., and then the simulation time and step size are set according to the characteristics of the sensitive area and the disturbance duration, and then the model is run. The model calculates the impact of the disturbance on various elements of the area according to the built-in algorithm. After that, key indicators such as soil erosion amount and vegetation biomass are extracted from the output results, and their variation laws are analyzed from the spatial and temporal dimensions. And methods such as Monte Carlo simulation are used to carry out uncertainty analysis to obtain the reliability and risk degree of the disturbance information, so as to provide a basis for subsequent decision-making.

[0052] In a possible implementation manner, the specific processing process of step S130 is as follows: for each sensitive area, the following steps are executed: based on the regional characteristics of the sensitive area, determine the soil parameter set of the sensitive area, and based on the construction information of the target power transmission and transformation project, determine the regional construction information set of the sensitive area; based on the soil parameter set and the regional construction information set, construct the initial simulation model of the sensitive area; obtain the influence law of the target power transmission and transformation project, and based on the influence law, correct the initial simulation model to obtain the simulation model of the sensitive area; based on the construction information of the target power transmission and transformation project, determine the construction stage and influence duration of the sensitive area, and based on the constructed simulation model, determine the disturbance information of the sensitive area during the construction stage and the influence duration; the disturbance information includes multiple disturbance characteristics and the corresponding disturbance degree of each disturbance characteristic.

[0053] In some embodiments, the initial simulation model is a simulation model preliminarily constructed according to data such as soil parameters and construction information. The initial simulation model has not been corrected, and its simulation results may not be accurate.

[0054] In some embodiments, the regional construction information set mainly includes the construction information of the power transmission and transformation project in the region. For example, the construction situation of the power transmission and transformation project (specific construction stage and how long it has been operating), and the specific engineering links of the power transmission and transformation project in this region (such as including a substation in the region, or only having transmission facilities in the region).

[0055] Among them, by summarizing the impact of power transmission and transformation projects with construction times prior to this power transmission and transformation project on the soil, the general impact law of power transmission and transformation projects on the soil can be obtained. Combining with the regional characteristics of the sensitive area, the impact law of the target power transmission and transformation project in the sensitive area can be obtained.

[0056] In some embodiments, the construction stage can be divided into a foundation construction stage, an equipment installation and line erection stage, a commissioning stage, and an operation stage. The impact duration mainly refers to the duration of these construction stages.

[0057] In some embodiments, the disturbance information is obtained through prediction. The disturbance characteristics mainly include three aspects. One is the physical aspect, such as soil texture, structure, porosity, etc.; the second is the chemical aspect, such as pH value, nutrient content, heavy metal content, etc.; the third is the biological aspect, such as microbial community structure, enzyme activity, etc. The biological aspect can also include vegetation coverage rate.

[0058] In some embodiments, the disturbance degree is mainly obtained by comparing with that before the construction of the power transmission and transformation project. For example, the vegetation coverage rate before the construction of the power transmission and transformation project is 75%, and the vegetation coverage rate after the construction of the power transmission and transformation project is 50%. Then the disturbance degree is |75% - 50%|÷75% = 33.3%.

[0059] In a possible implementation manner, the specific processing process of step S130 is as follows: for each sensitive area, perform the following steps: based on the regional characteristics of the sensitive area, determine the engineering links of the sensitive area; based on the engineering characteristics of the target power transmission and transformation project, determine the impact law of the target power transmission and transformation project, and based on the engineering links of the sensitive area, determine the sub-impact law of the sensitive area; based on the sub-impact law, correct the soil parameter set in the initial simulation model to obtain the simulation model of the sensitive area.

[0060] In this embodiment, the engineering links mainly include substations and transmission lines. The construction of a substation requires a large occupied area and is difficult to restore. The occupied area of a transmission line is small and it is relatively easy to restore. The impact laws of substations and transmission lines are also different.

[0061] In some embodiments, determining the sub-impact law of a sensitive area mainly means determining whether a substation is included in this sensitive area. If a substation is included in the sensitive area, the sub-impact law of the sensitive area is the impact law of the substation. If a substation is not included in the sensitive area, the sub-impact law of the sensitive area is the impact law of the transmission line.

[0062] For each sensitive area, a simulation model is constructed based on its regional characteristics, and the disturbance information is determined accordingly. The simulation model constructed by fitting the regional characteristics can accurately restore the original complex ecological, geographical and other conditions of the sensitive area, making the subsequent simulation analysis more in line with the actual situation and improving the accuracy of judging the disturbance information. At the same time, by using the model to determine the disturbance information, the impacts of different types of disturbances (such as engineering construction, pollution emissions, etc.) on various elements of the sensitive area in the spatial and temporal dimensions can be comprehensively and dynamically presented in the virtual environment in advance, facilitating the early awareness of possible ecological damage, environmental changes, etc., and then providing a reliable basis for scientifically formulating response strategies, reasonably planning engineering activities, and effectively carrying out ecological protection measures, etc., to minimize the negative effects brought by the disturbance.

[0063] S140. Based on the disturbance information of each sensitive area, determine the corresponding initial restoration plan, and optimize the corresponding restoration plan based on the neighborhood information of each sensitive area to obtain the restoration plan for each sensitive area.

[0064] In some embodiments, after comprehensively and deeply analyzing the disturbance information of the sensitive area, an initial restoration plan matching it is determined according to the characteristics such as the type and degree of the disturbance. For example, if the sensitive area has disturbances such as vegetation damage and soil compaction due to the construction of a transmission and transformation project, and the ecological system in this area is relatively fragile and the vegetation restoration is difficult, then the initial restoration plan may include preferentially selecting plant varieties with strong local adaptability for vegetation reconstruction.

[0065] In some embodiments, the neighborhood refers to the area adjacent to the sensitive area, and the neighborhood information refers to the disturbance information of the area adjacent to the sensitive area. Each sensitive area may have one neighborhood or multiple neighborhoods.

[0066] In a possible implementation manner, the specific processing process of step S140 is as follows: for each sensitive area, perform the following steps: based on the disturbance information of the sensitive area, determine multiple disturbance characteristics of the sensitive area and the corresponding disturbance degree of each disturbance characteristic; based on all the disturbance characteristics and the corresponding disturbance degrees, calculate the disturbance factor of the sensitive area; based on the disturbance factor, extract the initial restoration plan of the sensitive area from the disturbance factor-restoration plan mapping set.

[0067] In some embodiments, the disturbance factor is:

[0068]

[0069] Wherein, R i is the disturbance factor of the i-th sensitive area, θ is the first disturbance factor repair coefficient, σ is the second disturbance factor repair coefficient, α i is the physical coefficient of the i-th sensitive area, βi is the chemical coefficient of the i-th sensitive area, γ i is the biological coefficient of the i-th sensitive area, j is the j-th soil physical property of the i-th sensitive area, k is the k-th soil chemical property of the i-th sensitive area, h is the h-th soil biological property of the i-th sensitive area, m is the number of disturbed soil physical properties in the i-th sensitive area, u is the number of disturbed soil chemical properties in the i-th sensitive area, p is the number of disturbed soil biological properties in the i-th sensitive area, T ij is the disturbance degree of the j-th disturbed soil physical property in the i-th sensitive area, α ij is the weight coefficient of the j-th disturbed soil physical property in the i-th sensitive area, H ik is the disturbance degree of the k-th disturbed soil chemical property in the i-th sensitive area, β ik is the weight coefficient of the k-th disturbed soil chemical property in the i-th sensitive area, S ih is the disturbance degree of the h-th disturbed soil biological property in the i-th sensitive area, γ ih is the weight coefficient of the h-th disturbed soil biological property in the i-th sensitive area.

[0070] In some embodiments, each disturbance factor in the disturbance factor - restoration plan mapping set corresponds to a disturbance factor range, and each disturbance factor range corresponds to an initial restoration plan. The initial restoration plan includes many aspects. At the ecological restoration level, there is vegetation restoration, which involves the selection of suitable plant species, the planning of planting methods and densities, and the maintenance plan; soil restoration, which improves the structure and restores fertility through physical and chemical means. If water body disturbance is involved, there is also aquatic ecosystem restoration, which uses various methods to purify water quality and reconstruct biological communities.

[0071] In a possible implementation manner, the specific processing process of step S140 is as follows: For each sensitive area, perform the following steps: Based on the neighborhood information of the sensitive area, determine the number of neighborhoods of the sensitive area and the neighborhood level of each neighborhood; Based on the number of neighborhoods and the neighborhood level of each neighborhood, determine the restoration coefficient of the sensitive area; Determine an initial restoration matrix based on the initial restoration plan of the sensitive area, and optimize each parameter in the initial restoration matrix based on the restoration coefficient to obtain a restoration matrix; Based on the restoration matrix, determine the restoration plan of the sensitive area.

[0072] In some embodiments, the neighborhood level refers to the priority of the neighborhood, and the calculation method of the restoration coefficient is as follows:

[0073]

[0074] where x iis the repair coefficient for the i-th sensitive area, q is the q-th neighborhood of the i-th sensitive area, Q is the number of neighborhoods of the i-th sensitive area, and y iq is the neighborhood level of the q-th neighborhood of the i-th sensitive area, and δ(y) q is the level weight of the q-th neighborhood level, and its value range is 0.7 - 1.2.

[0075] In some embodiments, the number of rows of the initial repair matrix is the number of rows, and the number of columns is related to the vegetation types, microbial types, and animal types in the initial repair plan. For example, if there are a total of 8 vegetation types, microbial types, and animal types included in the initial repair plan, then the number of columns of the initial repair matrix is 8 columns. The parameters in the initial repair matrix are the specific quantities of each vegetation type, microbial type, and animal type in the initial repair plan.

[0076] In this embodiment, the corresponding quantities of vegetation types, microbial types, and biological types in the initial repair matrix can be adjusted through the repair coefficient to obtain the repair matrix, and then the initial repair plan for the sensitive area can be adjusted through the repair matrix to obtain the repair plan.

[0077] The initial repair plan customized based on the disturbance information can accurately target the types and degrees of damage suffered by the area, and plan the repair measures in a targeted manner, laying a scientific and reasonable foundation for the subsequent repair work. Introducing the neighborhood information to optimize the plan can fully consider the synergy and complementarity of the surrounding areas. When determining the quantities of plants, microorganisms, and animals, it can combine the priority of the neighborhood and the number of neighborhoods, enabling the repaired area to better integrate into the surrounding ecological network and promoting the restoration of ecological balance. Considering the neighborhood during the repair process can effectively improve the feasibility and sustainability of the plan, and contribute to the restoration of soil disturbance in sensitive areas.

[0078] S150. Based on the repair plans of all sensitive areas, obtain the overall repair plan for the disturbed area.

[0079] In a possible implementation manner, the specific processing process of step S150 is as follows: For each sensitive area, determine the sensitive area closest to it and multiple spaced areas in each target direction; for each spaced area, based on the repair plans of the two sensitive areas corresponding to the spaced area, determine the spaced repair plan for the spaced area; based on the repair plans of all sensitive areas and all spaced repair plans, determine the repair plan for the disturbed area.

[0080] In this embodiment, it is necessary to first determine the regional characteristics of the interval region, and determine whether the difference between the regional characteristics of the interval region and the regional characteristics of its corresponding two sensitive regions meets a preset value. If the preset value is met, the repair plan for the interval region is determined through the repair plans of the two sensitive regions. If the preset value is not met, first determine the initial interval repair plan for the interval region, and then adjust the initial interval repair plan for the interval region through the repair plans of the two sensitive regions.

[0081] In some embodiments, the interval region is the region separated in a certain direction between two sensitive regions, and the target orientation can be due east, due west, due south, due north, southeast, northeast, southwest, or northwest. For example, in the due east direction, the sensitive region closest to sensitive region 1 is sensitive region 2, and there are 3 regions between them, then these 3 regions are all interval regions.

[0082] It should be noted that when the regional characteristics of the interval region meet the conditions, the interval repair plan needs to be determined through the repair plans of the two sensitive regions corresponding to this interval region. When the regional characteristics of the interval region do not meet the conditions, determine the interval matrix through the initial interval repair plan of the interval region, and determine the adjustment parameters through the information of the sensitive regions.

[0083] The adjustment parameter is:

[0085] where G(c) w is the adjustment parameter of the w-th factor of the interval region c, d1 is the distance between the interval region c and its corresponding first sensitive region, d2 is the distance between the interval region c and its corresponding second sensitive region, w1 is the number of the w-th factor in the first sensitive region, w2 is the number of the w-th factor in the second sensitive region, and μ is the adjustment coefficient.

[0086] In a possible implementation manner, the specific processing process of step S150 is: for each interval region, obtain the distance between the regional center of this interval region and the regional center of each corresponding sensitive region, and determine the interval repair plan for this interval region based on the distance and the corresponding repair plan.

[0087] In some embodiments, after obtaining the distances between the regional center of the interval region and the regional centers of the corresponding two sensitive regions, it is necessary to determine the proportion according to these two distances, and adjust the repair plans of the two sensitive regions respectively through the proportion, and then the repair plan of the interval region can be obtained by integrating the two adjusted repair plans.

[0088] Determine the project characteristics and disturbed areas based on the construction information of the target power transmission and transformation project, divide the disturbed areas to obtain multiple regions; collect the regional characteristics of each region, determine the sensitive areas according to the regional characteristics, further construct a simulation model based on the regional characteristics of the sensitive areas, determine the disturbance information through the simulation model, and determine the initial repair plan. Then optimize the repair plan according to the neighborhood information to obtain the repair plan for the sensitive areas, and further obtain the overall repair plan for the disturbed areas based on the repair plans of all sensitive areas. Determining the disturbance information through the simulation model reduces the use of manpower and material resources, and can obtain the disturbance information of all soils more comprehensively. Determining the sensitive areas through the regional characteristics and determining the corresponding repair plans through the disturbance information of the sensitive areas improves the repair accuracy of the sensitive areas.

[0089] Determining the project characteristics and disturbed areas based on the construction information of the target power transmission and transformation project can reasonably plan the repair work according to the actual situation of the project. The regional division is based on the project characteristics and adjusted in combination with the regional characteristics, making the internal conditions of the regions more homogeneous, which is conducive to accurate repair, improving efficiency and effect, facilitating monitoring and evaluation, and protecting the ecological balance. Determining the sensitive areas comprehensively considering multiple factors can accurately lock the key repair areas. Constructing a simulation model in combination with the regional characteristics can accurately restore the situation, show the disturbance impact in advance, and provide a basis for scientific decision-making. The initial repair plan is customized based on the disturbance information, with strong pertinence. Considering the neighborhood information to optimize the surrounding coordination improves the feasibility and sustainability of the plan and realizes the efficient repair of the sensitive areas. Finally, integrating the overall repair plan of the disturbed areas based on the repair plans of the sensitive areas can repair the soil disturbance as comprehensively as possible.
