| 摘 要： | 地质环境评价可查明地质环境状态，有利于资源合理开发，有效减免地质灾害的发生。本文依据焦家金成矿带的地质环境特点及现状，选取地形地貌、工程地质类型、区域地壳稳定性、地下水环境质量、海水入侵、采坑及尾矿库、地面塌陷及伴生地裂缝、崩塌等12个评价指标，借助MapGIS强大的空间分析及信息处理能力，绘制相应的专题图，采用层次分析法（AHP）确定各指标的评价权重，采用综合指数法，对研究区地质环境进行评价，将焦家金成矿带地质环境质量划分为环境差区、环境较差区、环境一般区、环境良好区4个等级并进行分析说明。研究结果可为矿山环境的保护与修复提供对策和建议，为半岛蓝色经济区建设提供基础地质数据和科学依据。

| Abstract: | Geological environment evaluation can find out geological environment state. It is favorable for rational development of resources and preventing geological disasters effectively. 12 evaluation indexes have been selected according to the characteristics and present situation of geological environment of Jiaojia gold metallogenic belt, such as topography and geomorphology, engineering geological type, regional crust stability, groundwater environmental quality, seawater intrusion, mining pit and tailing reservoir, ground subsidence and associated ground fissures and collapse. By using MapGIS spatial analysis, information processing and drawing, geological environment quality of Jiaojia gold metallogenic belt has been divided into 4 grades according to the evaluation weight of each index through analytic hierarchy process (AHP), they are environment bad area, environment poor area, environment general area and environment good area. The research results can provide countermeasures and suggestions for the protection and restoration of the mine environment. It can provide basic geological data and scientific basis for the construction of the peninsula blue economic zone. |
