摘要

Wind energy density was calculated based on average wind speed and air density, and the distribution of wind energy density and its relation with the distribution of sandstorm in Hexi Corridor in Gansu Province were revealed. Moreover, the ecological effect of wind power development on the reduction of local sandstorm and sand flow was estimated. The results show that if the maximum rotor power coefficient of a wind-driven generator is 0.5, the forward movement speed of sand body (or desert) (8 827 km x1 m x1 m) will reduce by 1 m every year through the development and conversion of wind energy resources in Hexi Corridor. If the proportion of exploitable wind energy resources is 50% , the forward movement speed of sand body (or desert) (4414 km x1m x1m) will decrease by 1 m every year. It is clearly seen that wind power industry has obvious effects on the control of sandstorm and sand flow. Wind energy resources in Hexi Corridor have great development potential, and wind power industry can bring both ecological and economic benefit to people.
