Abstract: Based on the field observation of wind speed, roughness, wind-break potency and sediment yield in Huang Yangtan sandy land, this paper analyzed the mechanism of controlling wind erosion under different measures. The results are mainly as follows: the small network of narrow-band which has a high performance in wind-break is a reasonable protection forest allocation in sandy areas farmland. In addition, the surface roughness of coverage and stubble in different ways are orders of magnitude difference to the autumn bare land. When there is the same density of coverage and stubble, the surface roughness and wind-break potency increase along with the rise of coverage and stubble height. On the other hand, the surface roughness and wind erosion resistance increase with the height of cover and stubble in the case of the same coverage.
