摘　　要：采用美国环保署最新的MOVES2014a模型并对其进行本地化修正,获得了海口市机动车尾气排放因子,结合2015年海口市机动车的保有量、车型构成和年均行驶里程数据,计算了海口市不同车型、不同燃料类型和不同国标机动车的污染物排放总量和排放分担率.研究结果表明:2015年海口市机动车的HC,CO,NO_X和PM排放量分别是5 675 t,46 014 t,9 232 t和1 006 t;轻型汽油客车是HC和CO的主要贡献车型,其贡献率分别占44.3%和72.2%;柴油车的NO_X和PM排放分担率分别为57.1%和85.6%,是其保有量占比的4.9倍和7.0倍;保有量占比仅为11.7%的国Ⅰ及国Ⅰ前机动车,其HC,CO,NO_X和PM排放分担率分别达到46.4%,46.9%,42.7%和54.9%.In the report, the modified USEPA MOVES2014a model was used to obtain the emission factors of mo- tor vehicles in Haikou. Based on the population, types and the Vehicle-Miles of Travel （VMT） of the cars of Haikou in 2015, the total amount of pollutants and the sharing rates of the vehicles with different types, different fuel usage and different emission standard were calculated. The results showed that the total emission of HC, CO, NOx, and PM was 5 675 t, 46 014 t, 9 232 t and 1 006 t, respectively, in 2015. Light gasoline passenger vehicles were the major contributor of HC and CO, and the sharing rates was 44.3% and 72.2%, respectively. The NOx and PM contribution rates of diesel vehicles was 57.1% and 85.6%, respectively, and which was 4. 9 times and 7.0 times as much as the number of diesel vehicles, respectively. We also found that the contribution rates of HC, CO, NOx and PM emission of Euro I and Pre-Euro I vehicles with the population of 11.7% was 46.4%, 46.9%, 42.7%, and 54.9%, respectively.
