摘要
以斜坡单元作为评价单元,通过建立区域地质环境背景、资源损毁和地质灾害3要素评价指标体系,对各评价指标进行量化,赋予权重,利用GIS图层叠加分析,对许昌市矿山地质环境进行分区评价.分区结果与现状调查结果较为一致,验证了此方法的实用性,为规划与治理该地区矿山环境地质问题提供参考依据.
Taking slope unit as evaluation unit,through establishing the evaluation index system of three factors including regional geological environment background,resource damage and geological hazard,the evaluation indexes are quantified and weighted to make the zoning evaluation of mine geological environment in Xuchang City by layer overlapping analysis of GIS technology. The zoning results are consistent with the current survey,which verifies the practicability of the method and provides reference for planning and treatment of mine geological environment in the area.
