摘　　要：为掌握区域大气污染物排放特征,系统分析2023年临沂市人为源大气污染物排放数据。采用自下而上的方法编制排放清单,从时空维度进行分布特征研究。结果表明,工业过程源和化石燃料燃烧是污染物的重要来源。其中,工业过程源贡献可吸入颗粒物(PM_(10))、细颗粒物(PM_(2.5))和挥发性有机物(Volatile Organic Compounds,VOCs)排放量的最大份额,分别为273.15万、193.86万、116.83万t;化石燃料燃烧在SO_(2)和氮氧化物(NO_(x))排放中占主导地位,分别为78.32万、129.87万t。污染物排放呈现显著的季节性变化,SO_(2)和NO_(x)在冬季达到年均水平的1.37倍,夏季降至年均的0.85倍;空间分布上具有明显的区域集聚特征,高排放区主要集中在重工业城市和沿海地区。研究结果为临沂市制定差异化的大气污染防治策略提供科学依据,有助于改善区域空气质量。In order to understand the characteristics of regional air pollutant emissions,a systematic analysis of anthropogenic air pollutant emissions data in Linyi city in 2023 is conducted.The bottom-up approach is adopted to compile emission inventories,and study distribution characteristics from a spatiotemporal perspective.The results indicate that industrial process sources and fossil fuel combustion are important sources of pollutants.Among them,industrial process sources contribute the largest share of inhalable particulate matter(PM_(10)),fine particulate matter(PM_(2.5)),and Volatile Organic Compounds(VOCs)emissions,with emissions of 2.7315 million,1.9386 million,and 1.1683 million tons,respectively;fossil fuel combustion accounts for the dominant emissions of SO_(2) and nitrogen oxides(NO_(2)),with emissions of 0.7832 million and 1.2987 million tons,respectively.The emissions of pollutants show significant seasonal changes,with SO_(2 )and NO_(x)reaching 1.37 times the annual average level in winter and decreasing to 0.85 times the annual average level in summer;there are obvious regional agglomeration characteristics in spatial distribution,with high emission areas mainly concentrated in heavy industrial cities and coastal areas.The research results provide scientific basis for the development of differentiated air pollution prevention and control strategies in Linyi city,which will help improve regional air quality.
