• 摘要：城市机动车污染物排放清单的建立是控制机动车污染的关键.本研究以2012年为基准年,通过对成都市轻型汽油客车技术水平分布、活动水平和保有量等数据的调查,将IVE模型本地化,计算了成都市2012年轻型汽油客车VOCs、PM、NO_x、CO的排放清单,并分析了清单的不确定性.结果表明:成都市2012年轻型汽油客车排放的VOCs、PM、NO_x和CO分别为2.23×10⁴ t、1.6×10² t、1.26×10⁴ t和2.03×10⁵ t;轻型汽油客车中黄标车VOCs、PM、NO_x、CO的排放量分别占排放总量的27.5%、18.1%、37.2%和42.5%,表明黄标车是轻型汽油客车污染物排放的主要来源;排放清单的不确定性主要来自于排放因子,VOCs、PM、NO_x和CO清单的不确定性分别为-31.67%~32.35%、-54.75% ~55.09%、-6.56%~6.76%和-12.22%~12.51%.

• Abstract：Establishment of vehicle emission inventory is the key of controlling motor vehicle pollution. Taking 2012 as the base year, this study provides essential data for the localization of International Vehicle Emission (IVE) model to estimate vehicle emission inventory of VOCs, PM, NO_x and CO and analyze the uncertainty of this inventory through the survey of technical level distribution, vehicle activities and population of light-duty gasoline cars in Chengdu. The results indicate:①In 2012, the total emission inventory of VOCs was 2.23×10⁴ t, PM was 1.6×10² t, NO_x was 1.26×10⁴ t and CO was 2.03×10⁵ t from light-duty gasoline cars in Chengdu; ②The emission of VOCs, PM, NO_x, and CO from light-duty gasoline Yellow Label Cars (YLC) accounted for 27.5%, 18.1%, 37.2% and 42.5%, respectively, of the total emission inventory which suggested that YLCs were the main source of pollutants of light-duty gasoline cars; and ③ Emission factors contributed mostly to the emission inventory uncertainty. Uncertainty of VOCs, PM, NO_x and CO was -31.67%~32.35%, -54.75% ~55.09%, -6.56%~6.76% and -12.22%~12.51%, respectively.
