By statistics and calculation of the wind data, systematic research is made on the characteristics of wind regime in the Bosten Lake basin. The annual average wind speed is rather small, generally, it is 1.6-3.0 m·5s^-1; the effective time of sand-driving wind when the wind speed is more than or equals to 6.0 m·5s^-1 is obviously different in various regions. Among them, the days of sand-driving wind in Bayinbuluk account for 55.59% of the total number of days, in Yanqi, Luntai, Hejing, it is 18.75%, 12.72%, 11.48%, 12.72% respectively, in the rest of the stations it is lower than 10%. As the wind speed scale increases, the frequency of sand-driving wind reduces, and it is mostly concentrated 6.1-10.0 m·5s^-1; Wind variability index is between 0.49 to 0.68 in research region, and it belongs to middle ratio, the characteristics of wind conditions belong to blunt bimodal or sharp bimodal; sand-transporting potential belongs to low wind energy environment, and there are huge regional differences.
