广州市移动源现状及其污染控制管理对策

The Current Situation of Motor Vehicles and Controlling Measures of Motor Vehcile Pollution in Guangzhou

通过对广州市机动车辆构成状况和发展趋势、车流变化与氮氧化物变化关系以及各类车型污染排放分担率的分析，结果表明：在排放污染物的移动源中，小型车（ 出租车及其他小型车） 和摩托车是一氧化碳、碳氢化合物的主要排放源；公共汽车等大型车是氮氧化物的主要排放源之一。并提出对广州市机动车污染控制应着重控制摩托车、小型车（ 特别是轿车，包括出租车） 、公共汽车的污染排放。

The constitute of motor vehicles and the development trends,the relationship of vehicle flow and nitrogen oxides,and the contribution rate of exhaust from every kind of motor vehicles in Guangzhou were analyzed. The results showed that light\|duty vehicles (including taxis) and motorcycles are main emission sources of carbon monoxide and hydrocarbon while heavy\|duty vehicles including buses are among main emission sources of nitrogen oxides. The focus of controlling vehicle emission in Guangzhou was proposed to be the control of emissions from motorcycles,light\|duty vehicles (especially saloon cars including taxis)and buses.
