Abstract: Based on the wind data of 1973—2015 collected from the Wudaoliang meteorological station, the temporal and spatial variations of wind regime characteristics were analyzed,including wind speed,wind direction,visibility and relative humidity in the Beilu River.The results showed that wind showed higher energy in Beilu River area,and the dominant wind directions were W and WNW,which concentrated in November to December (winter) and January to March (spring).After 2000,the wind speed tended to be stable,while sandstorms were more and more serious.It was mainly due to temperature rising which made the snow covered on the soil surface and frozen soil melted in winter and spring.Therefore the surface soil was out of protection so that sand material increased.In Beilu River,the main wind direction in observation time was W and WNW.It could be believed that sandstorms was of no significant difference on both north and south banks of Beilu River.So the number of sand barriers could be suggested to reduce in the South Bank,and that in the North Bank should be increased.In addition,some measures could be taken,aiming to transport sand to reduce sand sediment near the riverside sand barriers.
