临汾市人为源一次PM2.5排放特征及钢铁、焦化等重点行业管控建议

Characteristics of PM2.5 emissions from anthropogenic sources in Linfen City and suggestions for control of key industries such as steel and coking

  • 摘要: 临汾市产业结构以钢铁、焦化等重工业为主,空气质量在全国168个重点城市中多年内排名倒数。临汾市污染中首要污染物主要是PM2.5为主,编制临汾市人为源一次PM2.5排放清单能够为制定措施控制PM2.5排放提供理论依据。基于现场调研、市直部门数据获取以及统计年鉴获取活动水平数据建立的2020年临汾市1km×1km人为源一次PM2.5排放清单,研究该市排放结构、空间分布及不确定性。通过与卫星遥感数据、MEIC等研究结果对比分析,阐述该排放清单的可靠性和全面性。结果表明,临汾市PM2.5的人为源一次排放总量约为23498.2t,其中,道路扬尘源与民用燃烧源占比最大,分别为37.6%和15.8%;排放集中在临汾盆地内7个区县,且排放强度要远高于两侧山区地形的区县,西部区县的排放强度低于临汾东部区县,其中洪洞县、襄汾县及尧都区PM2.5排放量位居前3;各类排放源不确定性结果处于-27.1%~34.5%之间。空间分布上,与遥感反演浓度具有较高一致性,高值均集中于临汾盆地。

     

    Abstract: 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.
