摘　　要：简要介绍了法国Losphere公司ALS300型偏振Mie散射激光雷达的基本结构、探测原理及反演算法,并通过在重庆主城区2009年11月23～27日一次典型灰霾天气条件下连续的气溶胶激光雷达探测结果分析得出,重庆冬季典型灰霾天气下PBL平均高度约为600米,AOD值在4及以上。The detection principle,basic structure and inversion algorithm of French Losphere ALS300 polarization-Mie scattering lidar were briefly introduced.By ALS300 lidar,an experiment of atmospheric aerosol detection was done under typical haze weather conditions on November 23~27 in 2009 at Chongqing urban area.The results showed that average PBL height is about 600 meters and AOD almost exceed 4 under typical haze weather in winter Chongqing.
