Practical Analysis of Pollution Source Distribution Using Horizontal Scanning of Particle Lidar
LiDAR was used to observe a mild particulate matter pollution process in the urban area of Lijiang.The data was inverted to obtain the extinction coefficient and depolarization ratio of particulate matter to analyze the distribution characteristics of particulate matter in the horizontal direction,and to determine relevant information about the pollution source.The results showed that two sources of pollution,straw burning in the field near lkm east of the monitoring site and particulate matter emission from a Logistics Park 1.7km southeast of the monitoring site,contributed significantly to the pollution.By using laser radar horizontal scanning to trace and locate pollution sources,technical support could be provided for precise governance by environmental management departments in a timely manner,thus achieving source management.
