中文摘要	利用自动气象观测仪所记录的1年风速数据,计算并分析了柴达木盆地风速、风向及输沙势等风况特征的时空变化。结果表明:该区风速最大值出现在春季,最小值出现在冬季,季节变化明显,且在空间上表现为自西北向东南递增的趋势;起沙风风向以NW、WNW为主,主风向和次风向的组合在空间分布上存在明显不同,风况与沙丘类型比较吻合;常年以稳定的西北气流为主,东南气流所占比重小,仅出现在夏季;柴达木盆地整体属于中风能环境,一年中风沙活动最强烈的季节为春季,风沙活动强度由西北向东南逐渐增强。
英文摘要	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.
