The spatial analysis methods of atmospheric SO₂pollution based on MAPGIS

Abstract：On the basis of the analysis of the pollution feature, it has applied the spatial analysis of MAPGIS to the studies of pollution state of atmospheric SO 2 and the internal relations between SO 2 pollution and the sources in Jiaozuo city of Henan province, China.By building the dynamic classified system, the changing information of atmospheric SO 2 pollution in this area is obtained, and an other analysis on developing regularity of SO 2 is also made.
