摘　　要：利用L300米散射激光雷达对合肥市郊大气边界层进行长期系统观测。分析讨论了大气边界层气溶胶消光系数与温度、湿度的关系,大气边界层气溶胶消光系数垂直分布和时间变化的主要特征,给出了激光雷达探测的大气边界层高度的统计特征及其与无线电气象探空仪探测大气边界层高度的比较结果。This paper presents the long\|time observational results of the Atmospheric Boundary Layer (ABL) over Hefei using L300 Mie scattering lidar. Correlation among humidity, temperature and aerosol extinction coefficient in ABL is described. The spatial\|temporal characteristics of aerosol extinction coefficient in ABL are analyzed and discussed. The statistic results of height of ABL measured by lidar, as well as comparison with the radiosonde measurement are also presented and discussed.
