Description :
The AA. analyzed the spatio-temporal dynamic change of land-use type in Maotiao River watershed, a typical agricultural area with severe soil erosion in Guizhou Province, from 1973 to 2007 using Landsat MSS image in 1973, Landsat TM data in 1990 and 2007. Soil erosion change characteristics from 1973 to 2007, and soil loss among different land-use types were examined by integrating the Revised Universal Soil Loss Equation (RUSLE) with a GIS environment. The results indicate that changes in land use within the watershed have significantly affected soil erosion. They also provide useful information for decision makers and planners to take sustainable land use management and soil conservation measures in the area.
