Abstract: 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.
