基于RS、GIS与AHP的巴音高勒小流域矿集区地质环境综合评价

针对矿产资源集约化利用区开展综合地质调查评价,建立了适用于小流域矿集区的矿山地质环境综合评价指标体系,利用遥感解译信息提取结合实际调查进行数据标准化处理,层次分析法确定指标层权重,GIS进行叠加矢量分析,以巴音高勒流域为例进行了矿山地质环境综合评价,划分矿山地质环境严重影响区、一般影响区、轻度影响区,表明该流域矿业开发造成的环境影响主要分布于矿床形成的自然异常区,即高背景区域内,为矿山地质环境监测预警、地质环境恢复治理与土地复垦、服务有色金属基地绿色矿业发展提供了科学依据。

Comprehensive Evaluation of Geological Environment in Mineral Concentrated Areas of BayingaoleWatershed Based on AHP, RS and GIS

Comprehensive geological survey aiming at thecomprehensive evaluation of mine geological environment in ore concentration area have great significance to the development of green mining industry. The investigationevaluated the geological environment quality of typical small watershed of Bayingaole base on remote sensing,analytic hierarchy Processand GIS-establishing a comprehensive evaluation index system of mine geological environment suitable for small watershed mineral concentration areas, standardizing the data through information extraction from remote sensing interpretation combined with practical survey, calculating index weight by analytic hierarchy process model, dividing evaluation unitsby GIS overlay analysis in to the severe, general ,mild and no-impact influencing areas. The results show that the environmental impacts caused by mining development are mainly distributed in the natural anomaly area of ore deposit formation, i.e. in the high background area, which providingscientific basis for mine geological environment monitoring and early warning, geological environment restoration and management, land reclamation and green mine construction.
