摘　　要：通过对太原市机动车运营特征的分析,采用修正的MOBILE6.2模式,对主要参数进行本地化修正,计算了太原市机动车排放的气态污染物排放因子,并确定了太原市分车型污染物的排放总量和分车型的排放分担率。结果表明,2011年太原市机动车CO、HC和NOx的总排放量分别为42.44×104 t、3.93×104 t和4.71×104 t。分析得出,轻型客车是主要的排放源,分别占(质量分数)82.50%、76.61%和45.40%,其原因是由于轻型客车27.5%的年增长率以及较高的排放因子共同造成的;重型车是NOx排放的第二大排放源,占NOx总排放量的36.47%。以上两种车型是太原市机动车排放污染控制的重点。On the basis of localized ana fled MOBILE6.2 was applied to estimate lyses on vehicle travel characters in Taiyuan city, modi- the vehicle gaseous pollutant emission factor and calcu- late the emission quantity and share rate by vehicle classes. The results show that Taiyuan vehicle emission quantities of HC, CO and NOx achieved 42.44×10^4 , 3.93×10^4 and 4.71×10^4 ton, respectively, in 2011. The light-duty vehicle （LDV） was the major emission source, accounting for 82.5 %, 76.61% and 45.40% of total CO, HC and NOx emission, respectively, because of its high rate of growth （27.5%） and higher emission factor. It＇s worth noting that heavy-duty vehi- cle （HDV） was the second major emission source, accounting for 36.47% of the total vehicle NO; emissions. LDV and HDV mentioned above were the focus of vehicle emission pollution con- trol in Taiyuan city.
