文摘内容 The actual and potential water erosion rates of soils with different land covers in Hainan Island,China,were estimated based on the universal soil loss equation(USLE) and a 1:200000 Soils and Terrain digital Database(SOTER) Ddatabase,from which soil water erosion factors could be extracted.92.8% of the whole island had a current erosion rate of lowerthan 500t km^-2 a^-1.Soil erosion risk was considered to be high because of its abundant rainfall.Without vegetation tcover,the potential soil erosion ratewould be extremely high and 90.8% ofthe island would have a soil erosion rate higher than 2500t km^-2a^-1.Relative erosion vulnerability of different soil zones,landform types,and lithological regions of the island was compared by introducing a relative erosion hazard parameter α.Cambosols developed from siltstone and mudstone in low hill regions were pinpointed as soils with the highest erosion risk in the island。
