This paper describes methodological experience and provides data references for international counterparts to study soil erosion in karst landform areas. The lithological and desertification factors introduced in the soil erosion model accurately reflect and predict soil erosion conditions and spatial distribution characteristics in karst areas. Future studies on soil erosion in karst areas should include underground loss in the calculation scope.
