摘　　要：本文提出了一种基于GIS技术,实现矿产资源规划环境影响的定量评价方法.利用ArcGIS提供的空间分析功能,实现了敏感环境保护目标筛选、影响范围确定以及矿产资源开发对环境保护目标的影响程度定量描述.研究结合江苏省第二轮矿产资源规划草案,根据不同类型矿产资源对环境保护目标的影响特征,分别就其对生态环境、地质环境、水环境、大气环境等方面的影响进行了预测和评价.结果表明:江苏省矿产资源规划总体布局合理,不会对环境保护目标造成大的影响,但是部分矿产资源距离环境保护目标较近,需要在开发过程中加强保护.本文提出的评价方法,可以有效提高评价结果的科学性,避免过多人工干预对评价结果的影响;该方法可以客观地、定量地给出矿产资源对不同环境要素的影响程度和范围,为规划草案的修订提供科学建议.With the rapid increase in demand for mineral is becoming more and more important to coordinate the resources induced by the fast development of economy, it relationship among mineral exploration, exploitation and environmental protection. To abate the environmental impact caused by the mineral exploitation, one of the most important means is to assess environmental impact of mineral resources planning. The method for environmental impact assessment of mineral resources planning using GIS is proposed in this research. The identification and selection of environmental impact factors are introduced first, and then the system for environmental impact assessment is set up in this search. In this paper, taking the second round of environmental impact assessment of mineral resources planning for Jiangsu Province as example, the approach is introduced in detail. Through spatial analysis method provided by ArcGIS software, the environmental impact of mineral resources planning to ecological environment, geological environment, water environment, atmospheric environment and acoustic environment is given quantitatively. Based on the result of environmental impact assessment of mineral resources planning for Jiangsu Province, some valuable suggestions are also given. The application shows that GIS is a very practical and efficient method in environmental impact assessment of mineral resources planning. It can provide reasonable analysis processes, quantitative and visual results, which makes the environmental impact assessment more scientific.
