Linfen City, with its industrial structure mainly consisting of heavy industries such as coal coking and steel, has been in a serious state of coal smoke pollution, and its air quality has ranked last among the 169 key cities in China for many years. The primary pollutant in pollution in Linfen City is mainly PM2.5. Compiling a list of primary PM2.5 emissions from human sources in Linfen City can provide a theoretical basis for formulating measures to control PM2.5 emissions. Based on on-site research, data acquisition from municipal departments, and activity level data obtained from statistical yearbooks, the 2020 Linfen City 1km * 1km anthropogenic source PM2.5 emission inventory was established to study the composition, structure, spatial distribution, and uncertainty of emissions in the city. By comparing and analyzing the results of domestic research such as satellite remote sensing data and MEIC, the reliability and comprehensiveness of this emission inventory are elaborated. The results show that the total anthropogenic emission of PM2.5 in Linfen City is approximately 23498.2 tons, with road dust sources and civilian combustion sources accounting for the largest proportion, accounting for 37.6% and 15.8% respectively; The emissions are concentrated in 7 districts and counties within the Linfen Basin, and the emission intensity is much higher than that of the mountainous terrain on both sides. The emission intensity of the western districts and counties is lower than that of the eastern districts and counties of Linfen, with Hongdong County, Xiangfen County, and Yaodu District ranking among the top 3 in terms of PM2.5 emissions; The uncertainty results of various emission sources range from -27.1% to 34.5%. Compared with MEIC in terms of total emissions, it is within an uncertainty range (MEIC: 30905t; this study: 23498t). In terms of spatial distribution, it has high consistency with remote sensing inversion concentration, and the high values are concentrated in the Linfen Basin.
