摘　　要：基于Mie散射激光雷达,对成都地区大气边界层结构随时间的变化特性进行了研究。利用Mie散射激光雷达测量大气回波信号,由改进的Klett算法反演获得大气后向散射系数,应用误差函数拟合法并参照位温廓线获得并分析了成都地区大气边界层高度以及卷夹层厚度等特性。The variation characteristics of atmospheric boundary layer （ABL） with time were studied based on Mie scattering lidar in Chengdu. The atmospheric echo wave signal was measured by Mie scattering lidar, and the backscatter coefficient was obtained by ameliorated Klett algorithm. The characteristic parameters of ABL height and the entrainment layer thickness were obtained and analyzed based on error function fitting method according to potential temperature profiles.
