摘要
建立了2006年珠江三角洲(以下简称为珠三角)地区机动车排放清单,获得了该地区分车型、区域以及燃料类型的机动车排放分担率.结果表明:①珠三角地区不同车型的机动车污染排放分担率有显著差别,其中柴油大货车、汽油小客车和柴油小货车是机动车排放NOx的主要来源,摩托车、汽油小货车和汽油小客车是机动车排放VOCs的主要来源,柴油大货车、柴油大客车和柴油小货车是机动车排放PM10的主要来源;②广州、佛山、东莞和深圳等经济发达和快速发展地区的机动车污染物排放量均较大,这4个城市机动车NOx,VOCs和PM10的排放量之和分别占珠三角地区机动车排放总量的79.7%,69.8%和77.9%;③机动车燃油比例对污染排放影响显著.汽油车(含摩托车)对VOCs的排放分担率较大(约为93.8%),而柴油车对NOx和PM10的排放分担率较大(分别为61.5%和84.0%).
A vehiele emission inventory was developed for the Pearl River Delta （PRD） region in 2006. The inventory was used to analyze the contributions from different vehicle types, different cities, and fuel usage to the total vehicular emission in the PRD. The results show： （1） There are significant differences in the emission contributions among different vehicle types. Heavy-duty gasoline trucks, light-duty gasoline passenger ears, and light-duty gasoline trucks were the major NO, emission contributors. Motorcycles, light-duty gasoline trucks, and light-duty gasoline passenger cars contributed most to the VOCs emissions. Heavy-duty diesel trucks, heavy duty diesel passenger ears, and light-duty diesel trucks were the main contribution sources of PMl0. （2） The developed and rapidly developing cities such as Guangzhou, Fushan, Donggnan and Shenzhen are major contributors to total motor vehicle emissions in the PRD region; the emissions from these cities account for 79.7%, 69.8% and 77.9% of the total vehicular NO., VOCs, and PM10 emissions, respectively. （3） The ratio of diesel vs. gasoline showed significant effeets on pollutant emissions. Gasoline vehicles make significant contribution - about 93.8% - to total VOCs emissions, while diesel vehieles contribute about 61.5% and 84.0% to the total NOx and PM10 emissions, respectively.
