摘要
根据甘肃矿山实地调查资料,从矿山开发对生态地质环境的影响程度、地质环境背景条件、地质灾害发育程度及矿山恢复治理难易程度4方面确定影响矿山生态地质环境的指标体系,采用模糊综合评判方法,建立矿山地质生态环境定量评价模型。利用MAPGIS空间分析模块求取综合指数的突变点以确定矿山生态地质评价分区的阈值,综合分析综合指数的分布特征,编绘甘肃省矿山生态地质环境综合评价分区图。分区评价结果与实际情况吻合良好。
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 diffi- culty degree of mine restore governance, using fuzzy comprehensive evaluation method to build mine geoecological 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.
