摘　　要：针对西北生态脆弱区的矿山地质生态环境,综合考虑其现状和演变趋势、治理难度及抗干扰能力,应用层次分析法和模糊综合法开展矿山地质生态环境评价研究。结果表明:靖远县105座矿山中,地质生态环境影响严重的矿山13座,占比12.38%;影响较严重的矿山6座,占比5.71%;影响较轻的矿山39座,占比37.14%;影响轻微的矿山47座,占比44.76%。矿山地质生态环境影响中,地质灾害因素影响大。砖瓦黏土矿地质生态环境影响程度分级主要为“轻微”和“较轻”;煤矿地质生态环境影响程度分级为“严重”;建筑用砂石料及其他矿山地质生态环境影响程度分级主要为“轻微”“较轻”和“较严重”。The analytic hierarchy process and fuzzy synthetic method were used to evaluate the mine geo-ecological environment in the ecologically fragile area of northwest China by considering the status quo and the evolution trend,governance difficulty and an⁃ti-interference ability.The results show that the risk of geo-ecological environment was serious for 13 mines,accounting for 12.38%of total 105 mines in Jingyuan County;less serious for 6 mines(5.71%);mild for 39 mines(37.14%);and slight for 47 mines(44.76%).The factors of geological disaster have a great influence on the risk evaluation results.The risk of geo-ecological environment was classified mainly as“slight”and“mild”for brick and tile clay mines,as“serious”for coal mines and mainly“slight”,“mild”and“less serious”for construction stone mines and other mines.
