Building up a Spatial Database for Shixia Catchment of Miyun Reservoir in Beijing
This paper deals with the application of GIS technology for building up a spatial database with regard to the nonpoint source pollution in Shixia catchment in Beijing Miyun Reservoir area. On the basis of satellite remote sensing image,GIS(Archview) was applied to analyze 3-demension information about the geomorphy to investigate the non-point source pollution distribution in association with soil erosion information, and thus to pinpoint the essential pollution control region.
