Description

Technical Field

[0001] This invention relates to the field of mine ecological restoration system technology, and in particular to an integrated restoration system for ecological reconstruction and multifunctional land regeneration of abandoned mine sites. Background Technology

[0002] With the long-term high-intensity development of mineral resources, a large number of mining wastelands, such as pits, spoil heaps, slopes, and slag heaps, have been formed. These areas generally suffer from severe topographic fragmentation, significant damage to ecological structure, high risk of soil erosion, and lack of land use functions. This not only affects regional ecological security but also restricts the rational use of land resources around mining areas and regional sustainable development. Therefore, systematic ecological restoration and land function reconstruction of mining wastelands has become one of the important research directions in the field of ecological restoration.

[0003] Existing mine wasteland remediation technologies often focus on single ecological restoration measures or localized engineering measures, typically aiming at vegetation restoration or slope stabilization. They lack a comprehensive analysis of the overall spatial structure characteristics of mine wastelands and the needs for land regeneration. Furthermore, some technical solutions primarily evaluate the suitability of natural conditions during the remediation process, with less consideration given to regional social needs and the synergistic relationship between land functions. This results in insufficient matching between remediation solutions and regional development needs, affecting the efficiency of land reuse and the long-term stability of remediation effects.

[0004] Furthermore, existing decision-making methods for mine wasteland remediation often employ single-indicator or simple weighted evaluation approaches for functional zoning. These methods lack effective coordination mechanisms for the competitive relationships between different land function types, making it difficult to achieve synergistic optimization of multifunctional land regeneration goals. Consequently, they restrict the scientific and systematic nature of mine wasteland ecological restoration schemes. Therefore, it is necessary to propose a collaborative restoration technology system for mine wasteland ecological reconstruction and multifunctional land regeneration that comprehensively considers topographical features, natural constraints, and regional social needs. This system aims to improve the rationality and effectiveness of mine wasteland ecological restoration and land reuse decisions.

[0005] A review of publicly available technical solutions reveals that CN121258720A proposes an open-pit mine ecological restoration management and evaluation system. This system includes modules for data acquisition, database, data indicator system construction, restoration strategy generation, restoration effect evaluation, visualization, management decision support, and evaluation models. Through dynamic updates of the data indicator system and timely adjustments to restoration strategies, the system can adapt to various changes during the ecological restoration process, ensuring the smooth progress of restoration work. Simultaneously, real-time evaluation of restoration effects and scientific formulation of management decisions improve the efficiency and effectiveness of restoration work, avoiding resource waste and blind spots. Furthermore, this dynamic adjustment mechanism can promptly identify and resolve problems arising during restoration, reducing restoration risks and improving the success rate and sustainability of restoration work. However, this solution primarily focuses on the management evaluation and dynamic adjustment of strategies during the open-pit mine ecological restoration process. It lacks a collaborative analysis of the terrain structure characteristics, natural constraints, and regional social needs of the abandoned mine site. It fails to establish a multi-functional land regeneration-oriented comprehensive functional adaptation and competitive coordination zoning mechanism, making it difficult to achieve integrated restoration decision-making that coordinates and optimizes the ecological reconstruction and land regeneration functions of the abandoned mine site. Summary of the Invention

The engineering modification capability index value is determined according to the repair engineering design scheme, including the range by which slope cutting engineering can reduce the slope, the range by which soil covering engineering can increase the soil covering thickness, or the range by which support engineering can improve the slope stability coefficient. For the first The repair unit corresponds to the first The natural constraint intensity index value of the natural constraint condition parameter is used to characterize the deviation of the natural constraint condition parameter from the boundary value of the allowable range of the target land function type. The natural constraint intensity index value is calculated based on the difference between the structural characteristic parameter value and the boundary value of the allowable range of the target land function type.

[0039] Furthermore, the adaptation result output unit constructs a natural condition adaptation matrix based on the natural condition adaptation calculation results of each repair unit corresponding to different land function types and outputs it to the subsequent modules for processing.

[0040] This scheme introduces an engineering breakthrough coefficient, extending the traditional static natural adaptation model that evaluates solely based on natural conditions into a dynamic natural adaptation model that considers the impact of engineering modification capabilities. This enables land function adaptation analysis in abandoned mining areas to simultaneously reflect the synergistic relationship between natural constraints and engineering restoration capabilities, thereby improving the accuracy and feasibility of land regeneration functional zoning results.

For the first The repair unit and the first The spatial distance between the sources of social demand is obtained through GIS spatial analysis and calculation. The distance decay index is used to characterize the degree of decay of the influence of different types of social demand sources on land function type demand as distance changes. The distance decay index is determined by fitting spatial correlation analysis based on the spatial service radius of the social demand source point and historical land use change statistics. The distance exponential decay coefficient is used to correct the degree of demand impact during the long-distance demand propagation process. The distance exponential decay coefficient is determined by comprehensive calculation based on the scale level of social demand source points, service range level, and regional transportation accessibility analysis results.

[0054] Furthermore, the adaptation result output unit constructs a comprehensive function adaptation matrix based on the comprehensive function adaptation degree calculation results of each repair unit corresponding to different land function types, and outputs it to the zoning decision module as the input basis for determining the land regeneration function zoning type.

[0055] Furthermore, the zoning decision module includes a competition relationship analysis unit, an adaptation correction calculation unit, and a zoning type determination unit. The competition relationship analysis unit is used to analyze the functional competition relationship between different land function types based on the comprehensive functional adaptation degree of each restoration unit corresponding to different land function types, and calculate the functional competition coordination coefficient of each restoration unit corresponding to different land function types.

[0069] Example 3:

[0070] This embodiment should be understood to include at least all the features of any of the foregoing embodiments, and to further improve upon them;

[0071] This embodiment provides an integrated restoration system for ecological reconstruction and multifunctional land regeneration of abandoned mining areas. A typical open-pit and spoil heap complex of abandoned mining areas, covering approximately 2.4 square kilometers, was selected as the experimental area. The study area was spatially gridded to obtain 126 restoration units. The area of ​​each restoration unit was controlled within the range of 1.5 to 3 hectares to improve spatial analysis accuracy while also considering engineering construction efficiency. The terrain structure analysis module uses UAV laser point cloud data with a spatial resolution of 0.5 meters and DEM data with a spatial resolution of 2 meters to fuse and model the three-dimensional terrain of the mining area. A slope threshold classification method was used to identify areas with slopes greater than 28 degrees as high-risk slope structures, areas with elevation differences exceeding 12 meters as typical pit structures, areas with bare rock ratios exceeding 65% as priority areas for soil covering and restoration, and areas with slope stability coefficients below 1.15 as priority areas for reinforcement and treatment. Based on these criteria, the restoration units were divided.

[0072] Furthermore, the natural condition adaptation analysis module establishes natural constraint adaptation parameter systems for forest land restoration function type, agricultural use function type, landscape recreation function type, and comprehensive development and utilization function type, respectively. It selects a slope range of 8 to 25 degrees as the preferred range for agricultural use, a soil cover thickness greater than 0.8 meters as the basic condition for vegetation restoration, and a slope stability coefficient greater than 1.20 as the safety condition for landscape facility construction. At the same time, it combines the slope shaping engineering capacity to reduce the slope by 5 to 12 degrees, the soil cover engineering capacity to increase the soil cover thickness by 0.5 to 1.8 meters, and the anchoring support engineering capacity to improve the slope stability coefficient by 0.08 to 0.25 to conduct a natural condition adaptation capability correction analysis, thereby forming a natural condition adaptation matrix for each restoration unit corresponding to different land function types.

[0073] Furthermore, the social demand analysis module identifies 11 residential cluster nodes, 4 industrial functional zone nodes, 6 public service facility nodes, and 5 regional planning control nodes within a 3-kilometer radius of the study area using spatial accessibility analysis. It also calculates the average access time from each restoration unit to these social demand source nodes using transportation network time cost analysis, controlling it to be between 6 and 28 minutes. Simultaneously, it comprehensively determines the social demand degree matrix by combining regional population density change trends, industrial land growth rate, and changes in public service demand levels. Specifically, the weight of residential cluster nodes for landscape and recreational function demand is set between 0.35 and 0.48, the weight of industrial functional zone nodes for construction and utilization function demand is set between 0.42 and 0.57, and the weight of public service facility nodes for comprehensive utilization function demand is set between 0.31 and 0.45.

[0074] Furthermore, the functional adaptation calculation module integrates the natural condition adaptation matrix and the social demand matrix to form a comprehensive functional adaptation matrix, and sets the natural condition constraint weight coefficient to 0.58 and the social demand driving weight coefficient to 0.42 according to the priority level of regional ecological protection, thereby forming a comprehensive functional adaptation ranking result for each restoration unit corresponding to different land function types.

[0075] Furthermore, the zoning decision module identifies the competitive relationship between different land function types through the functional competition coordination analysis method, and sorts and determines the comprehensive functional adaptation results after competition coordination. Among them, a total of 64 single-function dominant zoning repair units, 38 composite function collaborative zoning repair units, and 24 natural restoration transition zoning repair units are identified, thereby forming a complete land regeneration functional spatial layout structure.

[0076] Furthermore, the restoration path generation module automatically matches restoration engineering measures combination schemes based on the zoning type results. For single-function dominant zoning, the combination path of slope cutting and shaping engineering, soil covering and improvement engineering and vegetation restoration engineering is implemented first. For multi-functional collaborative zoning, the combination path of platform shaping engineering, drainage control engineering and landscape facility construction engineering is implemented first. For natural restoration transition zoning, the combination path of ecological enclosure measures and natural succession promotion measures is implemented first. The restoration implementation order is determined according to the engineering construction dependency relationship to form a restoration path implementation sequence.

[0077] Furthermore, such as Figure 5 , Figure 6As shown, a comparative experiment was conducted using the traditional single natural condition evaluation method as a comparison scheme under the same study area conditions. The traditional method only evaluates the functional suitability based on slope conditions, soil cover thickness conditions, and slope stability coefficient conditions, and uses the maximum suitability determination method for land functional zoning. The experimental results show that the spatial matching degree between the land regeneration functional zoning results identified by the system scheme described in this embodiment and the actual engineering implementation suitability evaluation results reaches 84.6%, while the spatial matching degree of the traditional natural condition evaluation method is 61.3%, improving the matching accuracy by 23.3%. At the same time, the restoration path scheme generated by the system scheme in this embodiment reduces the number of repeated adjustments of engineering measures by 41.2% during actual engineering implementation, reduces the average restoration cost per unit area by 17.8%, shortens the restoration project implementation cycle by 21.5%, and increases the regional vegetation coverage rate by 32.4%, while the vegetation coverage rate of the traditional scheme increases by 18.6%. The regional soil erosion intensity index decreases by 29.7%, which is significantly better than the 12.3% of the traditional scheme. This verifies that the system scheme in this embodiment can significantly improve the scientificity, coordination, and engineering implementation efficiency of the ecological restoration scheme for mining wasteland.
