摘　　要：The erodible particle size distribution, diameter range and separate content of three soils from semi-arid regions of China were determined at different wind velocities through wind tunnel simulation and dry sieving. It was demonstrated that soil erodibility by wind depends not only on the intrinsic soil properties, but also on the extrinsic erosion effect of the erosive winds. It was supposed that there existed general consistency in the mechanics of wind erosion on different soils.The erodible particle size distribution, diameter range and separate content of three soils from semi-arid regions of China were determined at different wind velocities through wind tunnel simulation and dry sieving.
