南京市移动源排放清单建立研究

Establishment Study on Emission Inventory of Mobile Source in Nanjing City

基于南京市移动源活动水平,采用适当的估算方法,建立了南京市2015年移动源排放清单。结果表明:南京市2015年移动源排放的CO、HC、NO_x、PM_(10)、PM_(2.5)、SO_2分别为9.61万t、1.88t、5.66万t、0.22万t、0.20万t和0.29万t。道路移动源中,小型载客汽车对HC和CO排放量贡献率最大,分别为61.0%和54.7%。重型载货汽车是NOx、PM_(10)、PM_(2.5)和SO_2四种污染物的主要排放来源,占比分别为54.0%、46.7%、45.8%和42.9%。非道路移动源中,船舶对CO、HC、NOx、PM_(10)、PM_(2.5)和SO_2排放量的贡献率均最大,分别为53.8%、49.4%、44.5%、57.8%、57.1%和89.6%。

Based on the activity level data collectedof mobile source, the mobile sourceemission inventory of Nanjing in 2015 was calculated and established by usingan appropriate estimation method.Results indicated that the total emissions of pollutants CO, HC, NOx, PM,0, PM-.5 and SO2 of mobile source in Nanjing were 96.1,18.8,56.6,2.2,2.0 and 2.9kt, respectively. For on-road mobile source, the small passenger cars were the largest contributors for both CO and HC emission with the percentage of 54.7% and 61.0%, respectively. The heavy-duty trucks were the largest contributors for NOx and PM10 emission, as well as PM2.5 and SO2, which accounted for 54.0%, 46.7%, 45.8%and 42.9%, respectively. For non-road mobile source, the ship were the biggest contributors for CO, HC, NOx, PM10, PM2.5 and SO2 emission, accounting for 53.8%, 49.4%, 44.5%, 57.8%, 57.1% and 89.6%, respectively.
