The flow accumulation and catchment watershed of the Dexing copper ore district and the Fujawu copper ore district in Jiangxi Province were simulated by using 1∶50 000 DEM with the support of ArcGIS in this paper. Firstly,the authors divided the area into 2 watersheds named a and b respectively,then divided the watershed a into 3 small catchment watersheds. Supported by metallogeny and mining science,the authors used GeoEye-1 data of American satellite to make a quick survey of the solid waste in Fujawu copper ore district with the method of human-computer interaction,and found that the area is 2.105 km2. Then the authors made a spatial overlap on the distribution of solid waste and watershed delineation and found that, as the original topography of the site of solid waste has a large slope and a large thickness of accumulation,it poses a threat of debris flow to the residents in downstream areas like Yangcun and, what is more, because of the corrosion of surface water,the exposed wastes make a serious impact on the water quality of Jishui River as well as residents’ drinking water in downstream areas.
