Soil erosion is
one of the most critical eco-environmental issues in the Poyang Lake basin,
China. The purpose of this study is to discover the spatial pattern
of soil erosion, and predict soil loss and sediment yield,
and evaluate soil loss impacts on main reservoirs by using Universal Soil Loss
Equation (USLE), GIS and Remote Sensing (RS).
Firstly, five
erosion factors including rainfall erosivity (R), soil erodibility (K),
topographic factor (LS), cover and management factor(C), and conservation
supporting practice factor (P) were calculated and analyzed, respectively.
Secondly, annual
soil erosion and its spatial distribution were evaluated, and sediment yield
was subsequently predicted.
