Sand driving wind characteristics, drift potential(DP) changes and spatial difference of sand strength in Ebinur Lake Basin was analyzed based on the data of six national weather stations during the period from 2005 to 2011. The results are as follows:(1) The wind direction in the study area are NW and NNW, and the occurring frequency were 54.98% and 18.31%, respectively.(2) The threshold wind occurs mainly in April, May and June, the occurring frequency were 12.48%, 14.70% and 13.08%, respectively. There are big differences of sand drift potential in defferent seasons, and the drift potential was concentrated in the spring and summer.(3) The variability index is 0.94, It belongs to a single air damper characteristic, resultant drift potential(RDP) and resultant drift direction(RDD) are 988.86 VU and 126.5°(ESE-SE).(4) The wind strength of study area appears a high value point as Alashankou, while the low value point is a wide area.
