摘　　要：利用激光雷达对2005年春季北京地区沙尘天气进行了连续观测,表征了沙尘气溶胶的时空分布以及沙尘天气特征。2月至5月间北京共发生沙尘天气26次,其中强沙尘天气12次。并将激光雷达观测结果和GT-521光学粒子计数器的测定结果进行了对比。Continuous observations of dust aerosols in Beijing were made by polarization Lidar from Feb. to May 2005. The temporal and spatial distribution of dust aerosols and features of the sanddust weather were characterized. During this period 26 sand-dust events（among them 12 serious sanddust events） were observed. The results of Lidar observation and GT-521 optical particle counter were compared.
