“3s”技术巳成为研究地表资源环境最有利的手段之一。基于“3s”技术,利用IKONOS高分辨率遥感影像,结合其他数据获取攀西裂谷成矿带的遥感、地质、地理、气象信息,采用层次分析法建立矿山地质环境评价体系,对研究区矿山地质环境进行评价。评价结果显示研究区内矿山地质环境质量总体较差:①矿山开采对地表景观的破坏较严重,占用了大量的土地资源,且未进行有序恢复。②采矿活动引发的地质灾害数量较多、规模大,存在一定的地质灾害隐患。③研究区个铜矿、铁矿、铅锌矿等金属矿尾矿库数量较多,雨水冲刷易造成地表水污染。
Nowadays, "3S" technology has become one of the most favorable means to study the surface resources. Based on "3S" technology,with the use of the remote sensing date extracted from high-resolution IKONOS images and other data, the remote sensing, geological, geographic and meteorological data were obtained. By adopting the With the information provided by the data in Panxi rift valley metallegenic belt, the mine geo-environment assessment model is built with the ana- lytic hierarchy process to evaluate the mine geo-environment of the studied area. The evaluation resuhs indicate that the o- verall mine geo-environmental quality in study area is unsatisfactory:(1)Mining activities damage the landscape seriously, and occupy a large amount of land and having no ecological restoration after the exploitation of mineral resources. (~Mining activities lead to many large-scale geologic hazards and a number of hidden dangers. (3)There are many copper tailing, iron tailing,lead-zinc tailing and other mine tailings in study area,which easily results in surface water pollution once washed by rain.
