In terms of the impact of different land uses on soil erosion,the Xiangyanggou watershed was divided into five slope grade units with the aid of ArcGIS.Soil erosion in the units under the conditions of existed soil and water conservation measures was estimated using the universal soil loss equation,and was then contrasted to the case before adopting the measures.Results show that soil and water loss has been greatly controlled,and soil and water conservation measures have evidently plaid a relatively great role.However,the watershed is still suffering from medium erosion,and the 25°～35°slope grade unit contributes most of soil loss,followed by the 15°～25°and>35°slope grade units.Based on the analysis of estimated modulus for different slope grade units,suggestions for further soil erosion control are presented in combination with existed soil and water conservation measures.
