Based on the existing work, we give the detailed introduction of factors, such as soil texture, wind velocity, vegetation, crop stubble mulch, soil moisture, terrain, artificial factors and so on. We also elaborate the quantitative relation between all related factors and wind erosion amount. At last, we summarize the exiting wind erosion controlling measures. The main purpose of this paper is to provide some references for experiment studys on wind erosion of soil and putting forward feasible controlling measures.
