摘　　要：在我国,矿业城市的地质环境问题日趋严重,需要探索一套适合于区域矿山地质环境影响性评价的技术方法,以指导矿业城市或重点矿区的矿产资源开发和环境保护。以鄂东南大冶矿区(即大冶市)为例,以遥感调查数据为基础,建立了由地质环境背景、已有地质环境问题和矿山开采活动三方面组成的区域矿山地质环境影响性评价指标体系,采用传统的模糊综合评价方法,分别对自然状态下矿区的地质灾害易发性和采矿状态下的矿区地质环境影响性进行了定量评价。结果表明:(1)自然状态下,大冶矿区地质灾害高易发区、较高易发区、较低易发区及低易发区分别占评价总面积的3.29%、12.55%、24.53%及59.62%;(2)采矿状态下,大冶矿区地质环境影响性严重区、较严重区、一般、轻微区分别占评价总面积的13.63%、22.96%、33.95%及24.96%。评价结果可作为大冶矿区矿产开发规划和综合性地质环境治理的重要依据。Geo-environmental problems of mining cities have been increasing in China. It is necessary to assess mine geo-environment impact( MGEI) in these mining cities for instructing the mine development and protecting environment. RS data is adopted to assess MGEI in the Daye mining area in southeastern Hubei Province. A MGEI index system is established by considering geo-environment background,geo-environment problems and mining activities. The fussy comprehensive assessment method is employed to assess the geo-hazard susceptibility before mining and the MGEI after mining respectively. The result indicates that:( 1) Under the natural state,the high,medium,relatively low and low easy-happening areas of geological hazard take up 3. 29%,12. 55%,24. 53% and59. 62%,respectively.( 2) Under the mining state,the severely,less severely,relatively slightly and slightly impacted areas of mine geo-environment take up 13. 63%,22. 96%,33. 95% and 29. 46%,respectively. The assessment result can be applied in mine planning and comprehensive geo-environment reclamation.
