Abstract: This paper's authors made a quantitative study in wind tunnel on the relationship between vegetation coverage. moisture content of soil, soil texture and deflation quantity of soil in Korqin Sandy Land. In addition, the invesgated the critial values of different vegetation coverage and moisture content of soil to resist wind erosioon, and compated the deflation-resistant intensity of aeolian sandy soils with different grain distribution. These study resutls have certain reference value for applicating them to protect soil from wind erosion.
