Restricted heavily by the geology

soil erosion in karst regions of southwest China is obviously different from that in other regions. Due to the couple of chemical dissolution

gravitational erosion and water erosion

the erosion in the region had a mixture mechanism of soil surface loss and underground leakage. This paper summarized the characteristics of soil erosion briefly

including surface soil loss

underground soil leakage

soil erosion intensity and the grading standard

and the simulation of soil erosion process. Further

future research interests were discussed. From the point view of the research advance

the automation

located monitoring of soil and water loss was put forward

and the simulation model for dual soil and water loss should be developed further in karst regions of southwest China. This could give a reference for quantitative assessment of the effects of land use change on soil and water conservation

and then provide service for the control of rock desertification.
