[Objective] Based on the Chinese soil loss equation (CSLE), this study aims to explore the method to quantitatively calculate soil erosion and improve the accuracy of soil erosion monitoring and reflect the effect of soil and water conservation effectively and objectively.[Methods] By using the CSLE model, the remote sensing interpretation and the statistical analysis, we quantitatively assessed the soil erosion in the overlapping area of the Zhungeer Banner and Huangfuchuan river basin.[Results] The total erosion in the study area was 13.778 3 million tons in 2015, and the annual erosion modulus was 4 920.23 t/(km²·a). The erosion was mainly moderate erosion, mild erosion and strong erosion are followed.[Conclusion] The soil erosion was quantitatively analyzed with CSLE model, and several factors such as rainfall, soil, vegetation, topography and measures were considered, which could be used for quantitative study of soil erosion.
