The objectives were to analyze the effects of wind erosion under plough tillage and no-tillage, evaluate changes in soil physical, chemical and biological properties due to different tillage practices, and to discuss the effects of soil properties on wind erosion. Results showed that : (1) soil loss from plough tillage (FT) was as much as 3~8 times that from no-tillage (NT);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 0-10 cm topsoil layer than the plough tillage soil. In the 0-5 and 5-10 cm 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 10-20 cm under no-tillage were as much as 4.7, 2.8 and 3.8 times, respectively. (3) Plough tillage practice decreased available K at the 0-5 cm depth by 77% compared to no-tillage. A similar trend was observed for total N, soil organic matter (SOM) and available P, although decreases were lower than that of available K. A cross depths, the concentrations of SOM were lower in the plough tillage soils than in the no-tillage soil, but differences were significant (P <0.05) only at the 0-5 cm and 5-10 cm depths. (4) Microbial biomass carbon concentration under NT was 2.1 times that of PT in the 0-10 cm soil depth.
