摘　　要：为了给环保部门防控大气污染提供科学依据,联合侧向和后向散射激光雷达系统对近地面气溶胶后向散射系数廓线进行高分辨率探测。分析发现,近地面气溶胶后向散射系数廓线随高度变化不尽相同,大致分为4种情况:多层结构、随高度升高而增加、随高度升高而减小以及不随高度变化。分析了连续两个夜晚的气溶胶后向散射系数廓线随时空的变化情况,并对2014年3月至2015年2月合肥西郊82个夜晚数据进行了统计分析,得出近地面气溶胶后向散射系数廓线按季节的分布规律。In order to provide scientific basis for preventing and controlling atmospheric pollution to environmental departments, the profile of aerosol backscattering coefficient is detected with high resolution by using the side scatter and backscatter lidar system. From the cases study, the profiles of near-ground aerosol backscattering coefficient with altitude are different, which can be classified into four categories, multilayer structure, increasing versus altitude, decreasing versus altitude and invariant versus altitude. Two continuous nights profiles of aerosol backscattering coefficient with altitude and time are analyzed. The average profiles of seasonal near ground aerosol backscattering coefficient at the western suburb of Hefei are calculated by averaging 82 nights data measured from March 2014 to February 2015 by season.
