利用系留探空、近地层梯度铁塔及地面气象站观测的数据，对塔克拉玛干沙漠腹地一次沙尘暴天气过程前后大气稳定度、混合层高度、地面气象要素及风、温、湿廓线等大气边界层特征量进行了分析。结果表明：沙尘暴发生时大气层结变得不稳定，沙尘天气过程中大气稳定度经历了稳定-不稳定-稳定的转变；沙尘暴的发生抑制了白天混合层高度的发展，维持了夜间混合层的存在，缩小了混合层高度的日变化；沙尘暴天气是一个降温增湿的过程；沙尘暴过境前后大气层结发生了转变，边界层风、温、湿廓线都打破了原有分布规律，影响了大气边界层结构的发展变化。

By using the observation data of tethersonde systems, sueface layer gradient tower and ground weather station, some boundary layer characteristics, including the atmospheric stability, mixed layer height, surface meteorological elements, and the profiles of wind, temperature and humidity during a sand-storm were analyzed in hinterland of the Taklimakan Desert. Results are as follows：during the sand-storm, the atmospheric stability became unstable because of the weather system, and the atmospheric stability experienced the changes of stable-unstable-stable.The occurrence of sand-storm inhibited the development of the mixed layer height during the day, while it maintained the mixed layer at night, and reduced diurnal variation of the mixed layer height. Over the life-span of the sand-storm event, temperature decreased and humidity increased across the surface layer. The atmospheric stratification changed and destroyed the original distribution of profiles of wind, temperature and humidity in boundary layer, and changed the structure of boundary layer.
