The grassland erosion research on steep slopes is the basis and difficulty, which was studied by artificial rainfall experiments. Results showed the following: (1) Decreasing the stream power (Rω) is main way to decrease the interrill erosion. (2) The regulation effect of grass on stream power and soil erodibility are mainly achieved by grass cover and root volume, separately. (3) The contribution rates of root volume (RV), and soil bulk density (SD) to RK is 73.61%-97.94, and 0.04%-0.22%.
