The results showed that soil wind erosion was the near-surface wind-sand activity. The sediment particle saltates mainly in 7.5-43.5 cm. Wind sediment amount decreased along height, which correlate well with power function, exponent function and logarithm function. The sediment particle composition was influenced strongly by wind erosion intensity and topsoil characteristics. However, the regularity of sediment composition was distinct in a definite paticle size in different heights. Wind erosion amount increases with wind speed exponentially, which was influenced by times that the wind does.
