Notes:the soil bulk density is 1.13 g/cm3.

The differences of the patterns and the intensity of soil erosion in different geomorphologic locations are widely divergent（Table 1）.From2010 to 2015，the average soil erosion thickness of peak slope，strip，middle slope to foot slope on the shrub-grass slope were 0.47 cm/a，0.65 cm/a，0.46cm/a and 0.53 cm/a respectively，and the total modulus of soil erosion were 53.11 t/km2·a，220.35t/km2·a，494.38 t/km2·a and 1 048.08 t/km2·a respectively.Among these figures，surface soil erosion accounted for 7.56%，3.76%，24.28%，and23.80%respectively，and the soil leakage from surface to underground accounted for 92.44%，96.24%，75.72%and 76.20%respectively.The relative contribution rate of soil leakage and average thickness of soil erosion are maximum on steep slopes but minimum on gentle slopes.Conclusions can be drawn that the soil erosion reduces downward the slope，and the relative contribution rates of the soil leakage are positively correlated with the thicknesses of soil erosion.
