| 摘 要： | 大气气溶胶对人体健康环境和全球气候都有一定的影响,是大气污染的主要来源。为了提升空气质量,大气污染防治刻不容缓。把气溶胶探测激光雷达和测风激光雷达集成在车辆上,进行走航和扫描探测可获得立体的大气气溶胶时空变化状态图。以合肥和芜湖等地大气气溶胶探测为例,基于激光雷达走航车的探测数据,获得大气气溶胶消光系数时空分布图,搜寻污染物排放源和估算颗粒物的PM2.5输送通量。由此可知,激光雷达走航式探测技术是获得大气污染立体图像便捷的、有效的方法,可为大气污染防治提供精准的科学依据,具有重要的应用价值。

| Abstract: | Atmospheric aerosol has certain influence on human health environment and the global climate, and it is a major source of atmospheric pollution. In order to improve air quality, atmospheric pollution prevention and control is of great urgency. The aerosol detection lidar and wind lidar is integrated on a mobile vehicle,and three-dimensional spatial and temporal variations of atmospheric aerosol can be obtained by navigation and scanning detection. Taking the detection of atmospheric aerosol in Hefei and Wuhu as an example, based on the detection data of mobile lidar, the temporal and spatial distribution of atmospheric aerosol extinction coefficient was obtained, the pollutant sources were discovered and the total PM2.5 transportation flux of particulate matter in the city was estimated. It can be concluded that the technology of mobile lidar detection is a convenient and effective method to obtain three-dimensional images of air pollution, which can provide accurate scientific basis for air pollution prevention and control,and has important application value. |
