从矿产资源规划环评的现状出发,阐述了国内外环境影响评价方法。在对比分析了已有环境影响评价方法的基础上,提出了利用GIS(Geographic Information System)技术进行矿产资源规划环评的思路和技术框架,并围绕其中的关键技术,如空间信息存储、矢量数据图层的创建、缓冲区分区、栅格叠加与模型分析、距离制图等进行了详细的分析,并以江苏省矿产资源规划环境影响评价为例,验证了GIS应用思路和技术框架的可行性,其成果为矿产资源规划以及其它相关领域的规划环评提供了极有价值的参考。
According to the current situation of environmental impact assessment of mineral resources planning, the methods of this domain at home and abroad are systematically illustrated in this thesis. Based on comparative analysis of existing methods, the thought and technical framework of environmental impact assessment using GIS (Geographic Information System) is proposed. Moreover, some key techniques of GIS are analyzed in this thesis, such as spatial information storage, raster data layer creating, buffer analysis, DEM (Digital Elevation Model) creating, raster superposition and model analysis, distance analysis, typesetting, etc. Finally, the feasibility of thought and technical framework using GIS is verified by taking environmental impact assessment of mineral resources planning of Jiangsu Province as an example, and its results will provide valuable references for other relevant work.
