【摘要】：以露天矿生态环境的稳定性、宜人性和限制性为依据,采用AHP法建立了露天矿生态环境的评价指标体系,该指标体系由地貌、植被、气候、大气、土壤、地下水、人口和开采8项因素及其相关的22项指标组成。通过AHP法计算要素层及其相关指标的权重矩阵,得出对露天矿生态环境影响最大的因素是开采、植被和气候,影响最大的指标是地表扰动率、固体废物堆置率、植被覆盖率、土地复垦率和坡度角大于25°的面积比重。借助由模糊数学建立的露天矿生态环境隶属度函数、模糊矩阵并结合指标权重矩阵确定出的露天矿生态环境隶属度矩阵,就可以对露天矿的生态环境状况进行评价。实例评价表明:该评价方法使用方便,评价结果符合实际情况,值得推广和应用。
[Abstract]:Based on the stability, suitability and limitation of ecological environment of open-pit mine, the evaluation index system of ecological environment of open-pit mine is established by AHP method. The index system is composed of geomorphology, vegetation, climate, atmosphere, soil and groundwater. Population and exploitation of 8 factors and related 22 indicators composition. By using AHP method to calculate the weight matrix of element layer and related indexes, it is concluded that the most influential factors on ecological environment of open-pit mine are mining, vegetation and climate, and the most influential indexes are surface disturbance rate, solid waste stowage rate and vegetation coverage. The area proportion of land reclamation rate and slope angle is more than 25 掳. With the help of the membership function of ecological environment established by fuzzy mathematics, the fuzzy matrix and the ecological environment membership degree matrix of open-pit mine determined by index weight matrix, the ecological environment condition of open-pit mine can be evaluated. The example shows that the evaluation method is easy to use, and the evaluation result is in line with the actual situation, and it is worth popularizing and applying.
