摘　　要：结合武汉市环境参数以及机动车保有量情况,将MOBILE 6.2模型用于武汉市机动车污染物排放特征的本地化研究,计算得到不同车型的排放因子,并核算出武汉市机动车分车型的污染物排放量和分担率。结果表明,2014年武汉市机动车污染物总HC、CO和NO_x分别为7.78万t、59.61万t和6.32万t.八类车型中汽油轿车排放的总HC和CO分别占总量的69.71%和82.86%,是这两类污染物的主要贡献车型。这主要是由于近年来汽油轿车尤其是私家车数量的高速增长。对于NO_x的排放,其主要贡献车型为重型柴油车,仅有5.44%的保有量但其排放分担率却高达约60%,因此严格控制重型柴油车可以有效减少机动车污染物NO_x的排放。同样的由于汽油轿车的总量较大,其NO_x排放的分担率也达到31.65%.Combined with the environmental parameters and the number of motor vehicle in Wuhan,MOBILE 6.2 was applied to study the localization of emission characteristics of vehicle pollutants and estimate the vehicle pollutant emission factors,and furthermore,account the emission quantity and share rate of different classification vehicle.The results show that the vehicle emission quantity of total HC,CO and NOx was 7.78×10^4,59.61×10^4 and 6.32×10^4 tons,respectively.The light duty gasoline vehicle（LDGV）was the major emission sources of total HC and CO,which showed the emission share rate of 69.71% and 82.86% and was mainly due to the recent high growth of LDGV,especially private cars.For the major emission sources of NOx ,heavy duty diesel vehicles（HDDV）,which had only 5.44% of total vehicles,displayed the emission share rate of 60%.So strict control of HDDV could effectively reduce vehicle emissions of NOx pollutants.Meanwhile,the share rate of NOx emission for LDGV reached 31.65% because of the increased quantity of LDGV.
