摘要
文章以神东矿区为研究背景,根据矿区地表损害的实际情况,选取了14个破坏因子作为评价指标,用层次分析法把评价指标归并为地表环境、地表破坏、地质灾害3个因素,并分别确定了因素层和评价指标的权重,用梯形隶属度函数确定评价因子的隶属度矩阵,采用多层次模糊综合评价法对神东矿区地表损害程度做出评价。研究表明,神东矿区地表环境和地质灾害等级属于轻微损害,地表破坏等级属于中度损害,根据综合评价结果可以得到神东矿区的地表损害程度整体上属于轻度损害。
On the background of Shendong mining area, according to the actual situation of surface damage in the mining area, 14 damage factors are selected as evaluation indexes in this paper. Analytic Hierarchy Process is used to integrate the evaluation indicators into three factors： surface environment, surface damage and geological disasters, and determine the weight of factor layer and evaluation index. The membership function of evaluation factor is determined by trapezoidal membership function, and the degree of surface damage of Shendong mining area is evaluated by multi-level fuzzy comprehensive evaluation. The research shows that, the grade of surface environment and geo-hazard in Shendong mining area belongs to minor damage, and the grade of surface damage belongs to moderate damage. According to the results of comprehensive evaluation, it can be concluded that the degree of surface damage in Shendong mining area is mild damage as a whole.
