摘　　要：本文通过对洛阳市2015年颗粒物环境受体和污染源样品的采集和分析,利用CMB模型,对洛阳市大气颗粒物进行来源解析,结果表明,洛阳市颗粒物污染具有典型的复合型污染特征,PM_(2.5)中二次硫酸盐、二次硝酸盐、二次有机碳(SOC)等二次颗粒物污染突出,燃煤(燃煤电厂、供热)对PM_(2.5)污染贡献最大,达31. 5%;其次是工业工程、扬尘及机动车等。Based on the collection and analysis of particulate matter environmental receptors and pollution source samples in Luoyang City in 2015,this paper uses CMB model to analyze the source of atmospheric particulate matter in Luoyang.The results show that the particulate matter pollution in Luoyang City has typical composite pollution characteristics,in the PM 2.5 matters,pollutions of secondary sulphate,secondary nitrate,secondary organic carbon(SOC)and other secondary particulate matter are prominent.Coal combustion(coal-fired power plants,heating)contributes the most to PM 2.5 pollution,reaching 31.5%;followed by industry engineering,dust and motor vehicles.
