摘　　要：为准确掌握聊城市大气污染物排放情况,加强大气污染管控,本文采用“自上而下”与“自下而上”相结合的方法建立了聊城市2020年大气污染物排放清单.结果显示,2020年聊城市SO_(2)、NO_(x)、CO、VOCs、NH_(3)、PM_(10)、PM_(2.5)、BC、OC排放量分别为11.70×10^(3)、61.28×10^(3)、285.19×10^(3)、28.43×10^(3)、66.87×10^(3)、47.83×10^(3)、17.15×10^(3)、0.751×10^(3)、1.07×10^(3)t.其中,SO_(2)最大排放源为化石燃料固定燃烧源(64.96%),移动源为NO_(x)排放第一大源(71.27%),CO排放主要来源于工艺过程源(45.71%)和化石燃料固定燃烧源(32.88%),VOCs的主要排放源为溶剂使用源(37.11%)与工艺过程源(22.86%),农业源作为NH_(3)的主要排放源(87.65%),主要由畜禽养殖贡献.PM_(10)与PM_(2.5)的主要排放源为扬尘源(62.02%)、化石燃料固定燃烧源(17.88%)和工艺过程源(17.29%),BC和OC的主要排放源分别为移动源(90.79%)和化石燃料固定燃烧源(65.09%).空间分布结果显示,聊城市除NH_(3)以外的污染物高排放区域主要分布在人口密集、工业发达的东昌府区与茌平区,而NH_(3)高排放区域则主要分布在农业较为发达的冠县和莘县.为尽可能地降低排放清单的不确定性,需要在后续工作中优化活动水平数据质量,建立本地化排放因子数据库,为聊城市空气质量模拟预测与污染治理决策提供数据基础与科学支撑.To accurately understand the emission characteristics of air pollutants and strengthen the air pollution control in Liaocheng,a new approach combining both"top-down"and"bottom-up"concepts was adopted to establish the emission inventory of air pollutants in Liaocheng in 2020.The inventory results show that the emission value of SO_(2),NO_(x),CO,VOCs,NH_(3),PM_(10),PM_(2.5),BC,and OC in Liaocheng in 2020 was 11.70×10^(3),61.28×10^(3),285.19×10^(3),28.43×10^(3),66.87×10^(3),47.83×10^(3),17.15×10^(3),0.7516×10^(3)and 1.07×10^(3)t,respectively.The largest source of SO_(2)emission is the stationary combustion of fossil fuels(64.96%),and the largest NO_(x)emission comes from mobile source(71.27%).CO emission is mainly from processes(45.71%)and stationary combustion of fossil fuels(32.88%).The major emission sources of VOCs are the solvent use(37.11%)and processes(22.86%).NH_(3)is mainly from agricultural sources(87.65%)such as livestock and poultry breeding.The direct emission sources of PM_(10)and PM_(2.5)are dust(62.02%),stationary combustion of fossil fuel(17.88%)and process(17.29%).In contrast,the primary emission source of BC and OC is mobile(90.79%)and stationary combustion of fossil fuel(65.09%),respectively.The spatial distribution results show that the high pollutant emission areas in Liaocheng,except NH_(3),are mainly distributed in the densely populated and industrially developed Dongchangfu and Chiping.While the NH_(3)high-emission areas are mainly distributed in Guanxian and Shenxian,where agriculture is more developed.In order to provide a better data basis and scientific support for Liaocheng air quality simulation and prediction and the pollution control decision-making,it is highly necessary to further optimize the data quality of activity level and establish a database of local emission factors,minimizing the inevitable uncertainty of emission inventory.
