摘　　要：利用南京市货车活动水平数据,建立了南京市2013—2016年货车排放清单。结果表明,2013—2016年,南京市货车保有量除轻型货车略涨外,其余车型均有不同程度减少,且各车型国Ⅲ、国Ⅳ车辆所占比例提高。到2016年,南京市货车以国Ⅲ排放标准居多,国Ⅳ次之。2016年南京市货车CO、NOx、VOCs、PM_(2.5)、PM_(10)的排放量较2013年分别下降了53.5%、32.4%、61.9%、60.7%和61.1%。其中,重型货车是NOx、PM_(10)和PM_(2.5)排放的主要贡献车型,CO和VOCs排放主要来源于重型货车与轻型货车。Based on the activity level data of trucks,the truck emission inventory in Nanjing from 2013 to 2017 was established. Results showed that there was a different degree of reduction in trucks except light trucks which increased slightly from 2013 to 2016. Besides,the amount of trucks meeting the requirements of China Ⅲ and China Ⅳemission standards increased,and in2016 the China Ⅲ emission standards truck was the major model in Nanjing. Comparing to the year 2013,the emissions of CO,NOx,VOCs,PM2.5 and PM10 decreased by 53. 5%,32. 4%,61. 9%,60. 7% and 61. 1%,respectively in 2016. Heavy trucks contributed the most NOx,PM10 and PM2.5 emissions,while both the heavy trucks and light trucks were the two major contributors to CO and VOCs emissions.
