Abstract:: Dongbeigou watershed, in Pingcuan county of Hebei province, was selected as the case study area in terms of complicated and various spatial data of small watershed, which is difficult to be managed. The spatial data of hydrology, topography, land use and many others were mined using GIS and RS based on Quickbird remote sensing image with 0.61 m spatial resolution and DEM with 1:10000 scale and 5 m resolution. Meanwhile, the 3D model of the small watershed was set. And the geography database was also established to manage the spatial data. The results show that the technology of GIS and RS can be the high efficient methods for obtaining spatial data and the construction and management of the small watershed.
