Abstract:: According to the data on-the-spot investigation of mines in Gansu,the index system of the mine’s geological environment was determined in terms of the impact degree of mining on eco-geological environment,geological environmental background,the development degree of geological disasters and the difficulty degree of mine restore governance,using fuzzy comprehensive evaluation method to build mine geo-ecological environment quantitative evaluation model.A mutation point of the comprehensive index was obtained by using MAPGIS spatial analysis module in order to determine the partitioned threshold of the mine eco-geological evaluation.The distribution characteristics of the comprehensive index was synthetically analyzed,and the ecological geological environment evaluation partition map on mine in Gansu Province was compiled.Partition evaluation results coincided with the actual situation.
