| Abstract: | Taking the typical eolian sandy soil from Liudaogou micro-river basin of Shenmu county, north Shaanxi, the influence of moisture on the resistance of studied soil to wind erosion is ascertained by means of wind tunnel experiment.The conclusions reached are as follows:the
threshold wind erosion velocity of eolian sandy soil increases linearly with an increase of moisture content;the wind erosion rate(intensity)reduces with an increase of moisture content by the sec-and power function.A comprehensive moisture-based model suggested for the resistance of eolian sandy soil to wind erosion has be obtained. |

| Keywords: | soil moisture content threshold wind eosion velocity wind erosion rate comprehensive moisture-based model for soil resistance to wind erosion |
