摘　　要：以广东省佛山市为研究范围,主要采用COPERTⅣ模型研究了重点车型排气管与非排气管排放的PM2.5特征及其影响因素,并分析了佛山2012年机动车排放PM2.5的排放来源。分析表明:非排气管排放PM2.5随车重增加而增加,随车速提升而降低;排气管排放PM2.5随车速和排放标准的提升而降低;随着排放标准的提升,排气管和非排气管排放差异越来越小;2012年佛山市机动车非排气管排放的PM2.5占机动车PM2.5总排放的28.9%,且随着未来黄标车淘汰等机动车污染控制措施的执行,非排气管PM2.5排放将成为大气环境控制污染治理的内容之一。COPERT IV model was used to study vehicle exhaust pipe and non-exhaust pipe emissions of PM2.5 characteristics and its influencing factors in Foshan, Guangdong Province. PM2.5 from motor vehicle emission sources in 2012 was analyzed. Results showed that non-exhaust pipe emissions of PM2.5 increased with the vehicle weight upgrade and decreased with the speed upgrade. Exhaust pipe emissions of PM2.5 decreased with the speed and enhancing emission standards. With the enhancement of the emission standards, the exhaust pipe and non-tailpipe emissions difference was getting smaller. In 2012, the non-exhaust PM2.5 emissions were about 28.9% of the total traffic PM2.5 emissions. With the implementation of high- emission vehicles eliminated motor vehicle pollution control measures, non-exhaust pipe emissions of PM2.5 emission will become one of contents of atmospheric environment pollution control governance.
