大同煤矿区生态脆弱性评价

生态脆弱性评价是区域生态综合评价的重要依据。矿区生态环境脆弱性研究不仅对矿区的资源及环境有着重要作用,还指导了资源的合理利用,为矿区的可持续发展提供了意见。本文在生态脆弱性研究方法上,选择生态敏感性-生态恢复力-生态压力度模型,通过建立基于目标的第三个层次准则的判断矩阵,并加权汇总得出各个因素的重要性程度,依此方法,再建立基于目标的第二个层次准则的判断矩阵,运用生态脆弱性指数的计算方法,得出大同煤矿区的生态脆弱性指数,评价大同煤矿区的脆弱性。评价结果显示,大同矿区生态脆弱综合指数为0.3506,呈中度脆弱性。根据生态脆弱性结果为后续的生态环境恢复重建工作、制定综合治理策略及矿区的可持续发展规划进行指导。

The Ecological Vulnerability Assessment of Datong Mining

Ecological Vulnerability assessment is an important basis for regional ecological comprehensive evaluation. Vulnerabil-ity research of ecological environment plays an important role in the mining resources and the environment of the mining area, and provided advice the use of resources for the sustainable develop-ment of the mining area. This paper base on the ecological vulnerability research methods, through the establishment of objective criteria based on the third level of judgment matrix, and the importance of the factors, according to this method, create a second level based on objective criteria judgment matrix, using the calculation methods of ecological vulnerability index, drawn the ecological vulnerability index of Datong Coal Mine area, eval-uate the vulnerability of Datong Coal Mine area. The evaluation results of Datong Mining ecological vulnerability index was 0.3506, showing the general vulnerability. According to the result of the subsequent fragility of ecological environment, drawn up ecological restoration and reconstruction work, and the develop-ment of comprehensive management strategy for sustainable devel-opment planning and mining guidance.
