Through wind tunnel experiment, the rate of soil wind erosion and blown sand structure under condition of conservational tillage and conventional tillage were studied. The results indicated that:The mean rates of soil wind erosion under conservational tillage were 20 to 40 percent less than that under conventional tillage. A power functions was found between the rate of wind erosion and wind velocity in the eight simulated tillage conditions, and the rate of wind erosion increased faster with the increasing wind velocity under conventional tillage. Wind velocity of 14 m·s-1 was the significant point to aggravate soil wind erosion, while conservational tillage greatly decreased the rate of soil wind erosion when the wind velocity beyond 14 m·s-1. In the height of 0-20 cm, the sand transport rate under conventional tillage decreased within increasing height by a negative line function, while negative exponential functions were founded under conservational tillage. Under conservational tillage, the total volume of sand transport in 0-4 cm and sand transport percent between 0-4 cm and 0-20 cm were less than that under conventional tillage.
