| Abstract: | MapInfo, ARC/INFO workstation and GIS ArcView were used to establish agricultural non-point source pollution database in Wuchuan watershed, including boundary, landuse current position,water system, topography, etc. The digital elevation mode(DEM) was also generated. On the basis of DEM, surface analysis was carried on. As a result, the aspect and slope in wuchuan watershed were extracted. In addition, the spatial analysis model-Hydrology Function in ArcView are employed to model flow direction, flow accumulation and flow network based upon DEM. This work was expected to provide a fundamental data supply for the further research of agricultural nonpoint source pollution in Jiulong river watershed. |
