The soil losses in the Maotiaohe watershed in Guizhou Province, China, were estimated by applying Geographic Information System (GIS) technology, and adopting Revised Universal Soil Erosion (RUSLE). The spatial distribution of soil erosion characteristics in the watershed are presented. The soil erosion map was overlayed respectively with slope, aspect maps from DEM and land use maps to analyse the erosion status.
