Mine ecological restoration evaluation method

Abstract

The invention belongs to the field of ecological restoration evaluation, and particularly relates to a mine ecological restoration evaluation method, which comprises a mine ecological subsystem, a mine environment subsystem and a man-made reconstruction subsystem, the mine ecological subsystem comprises four evaluation indexes of land damage, water area, vegetation coverage and biological abundance, the mine environment subsystem comprises four evaluation indexes of an atmospheric environment, a surface water environment, an underground water environment and a soil environment, the man-made reconstruction subsystem comprises four evaluation indexes of land treatment, water body treatment, goaf restoration and solid waste treatment, and aiming at mine ecological restoration evaluation, a mine ecological restoration system which is scientific in analysis process, reasonable in index setting, comprehensive in coverage, convenient in index investigation and acquisition and high in operability is formed. According to the method, the overall ecological restoration effect of the mine can be scientifically evaluated, the ecological restoration effect of local blocks of the mine can be evaluated, and the ecological restoration effect of the mine can still be evaluated under the condition that some indexes are inconvenient to obtain or lack. The evaluation method not only can evaluate the comprehensive effect of mine and ecological restoration, but also can evaluate and judge the state and effect of each index.

Description

technical field [0001] The invention belongs to the field of ecological restoration evaluation, in particular to an evaluation method for mine ecological restoration. Background technique [0002] As the country pays more and more attention to the protection of the ecological environment, mine restoration, as an important part of the protection of the ecological environment, has been paid more and more attention and continues to be carried out. However, a unified evaluation method for mine ecological restoration has not yet been formed, which makes it difficult to evaluate and evaluate the effect of mine ecological restoration, resulting in the inability to effectively evaluate and guide mine ecological restoration work and make targeted improvements. At present, the ecological restoration of mines is evaluated by the method of single effect or single score accumulation or weighted accumulation, but this method cannot evaluate the ecological restoration of mines where some i...

Problems solved by technology

[0003] In order to make up for the deficiencies of existing technologies and solve the problem that the ecological restoration of mines that cannot obtain certain individual indicators due to conditional constraints cannot be evaluated, the improvement of the comprehensive effect of ecological restoration of mines and their blocks must rely on the state Or single indicators with poor effects can be improved to achieve, so that the follow-up improvement work of mine ecological restoration is more targeted and instructive. For this reason, the present invention proposes an evaluation method for mine ecological restoration
