Abstract Based on the annual wind data collected from the three meteorological stations by field observation, the temporal and spatial variations of wind regime, include wind speed, wind direction and sand drift potential, were conducted and analyzed in this paper. The results indicate that the seasonal variations of the local wind speed, according to the maximum value in the spring and the minimum value in the winter, were obvious. The wind regime increased from northwest to southeast. Although the direction of the sand driving wind is mainly NW and WNW in the area, the combinations between the first wind direction and the second wind direction were significantly different. The northwest wind, with a high proportion, was more important and stable than the southeast wind which rarely occurred but summer. The wind energy environment was intermediate in the Qaidam Basin. Annually, the sand activities were fiercest in the spring. Furthermore, the intensity of sand activities was gradually increased toward the SE of the study area.
