摘　　要：随着矿山的大开发,矿山地质环境问题越来越严重,在MAPGIS技术的支持下,以甘肃省矿山地质环境为例,采用了矿山环境综合指数评价模型,将各影响因素按其权重进行空间代数叠加.根据叠加的结果并结合综合评估指数的大小,将甘肃省矿山地质环境分为三级区,其中,严重区23个,较严重区22个,一般区1个,分别占全省总面积的50.000%,47.827%和2.173%,为矿山地质环境研究提供了一个良好的应用范例.Associated with mining, the geological environmental problems are becoming more serious. Based on MAPGIS. , we took Gansu province＇s mine geological environment as an example, used comprehensive index model as the assessment model, put those influencing factors into the overlay chart according to the weighted index, and at last got a resulting overlay chart. The resultant overlay map is categorized into three classes：severe, relatively severe, and moderate. It is found that in Gansu province, the zoning number and area percents which represents the severe mine geological account for 23 and 50. 000%, respectively, the zoning number and area percent which represents the relatively severe mine geological environment account for 22 and 47. 872%, respectively, while the zoning number and area percent which represents the moderate mine geological environment account for 1 and 2. 173%, respectively. So, this paper has given a good applied example for the mine geological environment study.
