详细介绍了最新研制的扫描式微脉冲激光雷达MPL－AS以及它的特点和应用，探讨了微脉冲激光雷达探测大气气溶胶水平消光系数分布的数据处理方法，并给出了实地探测和数据分析结果。另外本文也尝试用消光系数与ρ(PM₁₀)的相关关系，计算获得了ρ(PM₁₀)水平空间分布。实地探测的结果表明：扫描式微脉冲激光雷达不仅可以探测大气气溶胶消光系数廓线和云层结构及其随时间的演变过程，还可用于城市大气环境水平方向空中污染状况的自动化扫描监测，获取感兴趣区域气溶胶的时空分布，是有利于空气环境治理的实用工具。

The characteristics and applications of the newly developed scanning micro pulse lidar(MPLAS) are presented. The data process of MPL-AS is discussed and some of the initial experiment results are discussed. The ρ(PM₁₀) horizontal profiles by using the correlation of aerosol extinction and ρ(PM₁₀) are also obtained. The results show that MPL-AS can be applied to automate monitoring of city atmospheric environment to obtain aerosol distribution of the monitoring area. The MPL-AS is a portable, compact and continuous-working lidar, it is a new efficient instrument for atmospheric environment monitoring.
