中文摘要：

利用塔克拉玛干沙漠及周边地区观测资料,依据尘卷风热力学理论和方法,估算出在塔克拉玛干沙漠地区尘卷风对沙尘气溶胶贡献的年平均量为4.0×106t,年最大量为5.0×106t,与该地区沙尘暴的沙尘气溶胶年均贡献量相当.依赖于太阳辐射强度季节变化,尘卷风的起沙量具有与地面温度同步的季节变化规律.

英文摘要：

Based on the thermodynamic theory of convective plumes and vortices in the atmosphere boundary layer and by using the observational data in the Taklimakan desert and surroundings,the dust aerosol emissions from the convective plumes and vortices are estimated with annual average of 4.0×106t and the maximum of 5.0×106t with an equivalent contribution to dust aerosols from dust storms over the Taklimakan desert.Depending on the seasonal cycles of solar radiation intensity,the dust aerosol emissions from the convective plumes and vortices vary with the changes of surface temperature.
