Results showed that:(1) soil loss from plough tillage was as much as 3~8 times that from no-tillage; the aerodynamic roughness lengths under plough and no-tillage were 0.032, 0.417, respectively.(2) No-tillage soil contained more clay and fine sand in the 0-10cm topsoil layer than the plough tillage soil. In the 0-5 and 5-10cm soil depth, the bulk density, soil hardness and soil moisture were more under no-tillage than plough tillage. Especially, the soil hardness in 0-5, 5-10 and 10-20cm under no-tillage were as much as 4.7, 2.8 and 3.8 times, respectively.
