资源枯竭矿区生态环境损害评价指标体系研究

Study on Ecological Environment Damaged Assessment Index System of Resource-exhausted Mining Areas

资源枯竭矿区的环境污染和生态破坏程度是影响矿区生态修复规模和难易程度的重要参考性指标,评定矿区生态环境的损害程度对于生态修复规划具有实际意义。在现有的研究基础上,界定了资源枯竭矿区生态环境损害评价的内涵,运用层次分析法构建了资源枯竭矿区生态环境损害评价的指标体系,并介绍了每一指标的具体含义,最后以北京门头沟矿区为研究实例,对该区生态环境损害状况进行了评价,评价结果符合实际情况,在相关研究的应用中起到了重要作用。

The environment pollution and ecological damaged degree of the resource-exhausted mining area are the important reference indexes affected to the mining area ecological reconstruction scale and the difficult degree. The assessment on the damaged degree of the mining area ecological environment would have the actual meaning to the ecological reconstruction plan. Based on the available study, the intension of the ecological environment damaged assessment for the resource-exhausted mining area was determined. With the layer analy- sis method, the index system of the ecological environment damaged assessment for the resource-exhausted mining area was established. There were three layers for the index system. The paper introduced the certain meaning of each index. In the final of the paper, taking Beijing Mentougou mining area as the study case, the ecological environment damaged status of the area was assessed. The assessment re- sults could meet the actual condition and would play an important role to the application of the related study.
