摘要
定量分析计算机动车污染物排放特征 ,对城市汽车污染控制决策具有重要意义 .在利用实测数据确定基本参数的基础上 ,用 MOBILE5模型计算了北京市机动车污染物排放因子 ,获得了城区和全市机动车污染物排放总量和排放分担率 ,并分析了不同车型车种在城市区域汽车污染中的贡献率 .结果表明 ,北京市城区 CO,HC和 NOx 的排放总量中 ,汽车源排放分担率分别为 :78% ,83%和 46% .
It is very valuable for decision making on automotive pollution control to quantify the pollutant emissions from motor vehicles.Based on the determining of important parameters by testing Chinese vehicles, MOBILE5 model was used to calculate the composite emission factors of the vehicle fleet in Beijing.The overall emission amounts and the contribution rate of automobiles were achieved for the urban areas as well as the whole city.The sharing rate of different types of vehicles to the total vehicular emissions in urban areas was analyzed.Results showed that the contribution rate of mobile sources are 78%,83% and 46% respectively for the total emissions of CO,HCs and NO x in urban areas.
