AI Technical Summary

Technical Problem

Existing ecological restoration technologies for coal mine subsidence areas cannot accurately reflect the spatiotemporal evolution of the geological environment. Restoration plans lack specificity and cannot be coordinated with land and space planning, resulting in blind selection of restoration technologies that are easily disconnected from planning and serious waste of resources.

Method used

By acquiring multi-source historical geospatial data, a three-dimensional geological environment evolution model containing spatiotemporal attributes is generated. This model is then overlaid with constraint layers such as land use zoning and ecological protection red lines from the national land spatial planning. The dominant damage patterns are identified, restoration technologies that meet planning requirements are selected, coupled simulations are conducted to predict long-term impacts, and a multi-objective optimization model is constructed to obtain ecological restoration implementation plans.

Benefits of technology

This approach achieves precise alignment between ecological restoration technology for coal mine subsidence areas and national land spatial planning, avoiding a disconnect between restoration direction and planning, improving the relevance and long-term effectiveness of restoration plans, saving resources, and taking into account geological stability, hydrological health, and soil improvement.

Abstract

The present application relates to the technical field of ecological restoration of coal mines, in particular to an ecological restoration method and system for a coal mine subsidence area based on territorial space planning, comprising: obtaining multi-source historical geospatial data of a target coal mine subsidence area, generating a three-dimensional geological environment evolution model with time and space attributes through time and space fusion and standardization processing; superimposing land use zoning, ecological protection red line and urban and rural development boundary constraint layers in territorial space planning; identifying the dominant damage modes such as surface cracks and waterlogging in different areas of the subsidence area; screening repair technology options that meet the requirements of land class control; coupling simulation of the repair technology options and the three-dimensional model to predict long-term effects; combining the ecological safety pattern target to build a multi-objective optimization model to obtain an ecological restoration implementation plan. The method realizes the collaboration of ecological restoration of the subsidence area and territorial space planning, and improves the pertinence and scientificity of the restoration.
