[Objective] To understand the mechanism and characteristics of soil erosion, and the relationship between soil anti-erodibility and land use type.[Methods] Taking mulberry (Morus alba) garden and masson pines (Pinus massoniana) forest which are in Shangshe village, Yuexi County, Anhui Province as study objects. Collecting the soil at 0-40 cm level every 10 cm, measuring their porosity, specific surface area, disintegration index, root system characteristics.[Results] The soil anti-erodibility of masson pine forest was stronger than that of mulberry garden, and that in the range of 0-10 cm, mulberry soil root
