Ecological Environment Branch of Shushan District, Hefei, Anhui 230031, China Abstract : In order to further study the regional pollution distribution of urban atmospheric particles, based on the active remote sensing observation technology of atmospheric particles lidar, 24 —hour continuous scanning monitoring in Shushan District, Hefei City is conducted・ The results show that the lidar has monitored many kinds of particulate pollution sources such as dust sources on the construction site, cooking fume, etc. Ac­ cording to the comprehensive analysis of air station monitoring data, regional meteorological data and pollu­ tion source investigation, the pollution sources are mainly distributed in urban residential areas and various construction sites, and the concentration of particulate matter in hot spots ranges from 80ptg/m3 to 170ptg/m3, exceeding the
