基于RS和GIS的贵州大湾煤矿区矿山地质环境评价

根据贵州大湾煤矿区矿山开发多目标遥感调查资料，利用RS与GIS技术，在综合考虑研究区自然地理、地质背景、资源损毁、地质环境等基础上，构建了4个子评价系统15个指标因子的评价指标体系；用层次分析法来确定评价因子的权重，选用加权综合评价法，对贵州大湾煤矿区矿山地质环境进行了定量评价，并绘制了研究区矿山地质环境综合评价图；通过与矿山地质环境现状对比分析，其结果相吻合，评价结果真实反应研究区矿山地质环境现状。

The Evaluation of Mine Geological Environment in Guizhou Dawan Coal Mine Area Based on GIS and RS

According to the remote sensing data in Guizhou Dawan Coal Mine Area, using RS and GIS technology and considering the basic research of physical geography, geological background, resource damage, geological environment, 4 sub--evaluation systems inclu- ding 15 evaluation index systems are constructed. The analytic hierarchy process （AHP） is used to determine the weights of evaluation factors, and weighted comprehensive algorithm （WCA） is used for the quantitative evaluation of mine geological environment in Guizhou Dawan Coal Mine District, and the comprehensive evaluation schematics of mine geological environment in the study area is mapped. By comparison of the present situation of mine geological environment, the results can clearly reflect the present situation of the geological environment.
