【摘要】 建立机动车排放清单是实行机动车污染控制的基础。通过对澳门机动车保有量及其构成、车辆登记分布和累积里程分布的调查分析,获得了澳门机动车基本的运营特征参数。采用修正的MOBILE5模式和PART5模式,计算了澳门机动车排放的气态污染物和颗粒污染物的排放系数,并确定了澳门机动车污染物的排放总量和分车型的排放分担率。1999年澳门机动车CO,NOx,HC,PM10和PM2.5的总排放量分别为15852t,2416t,2449t,141t和128t。研究结果表明,控制摩托车和汽油轿车可以有效削减HC和CO的排放;而对于NOx和颗粒物,公共汽车和重型柴油车应是主要的控制车型。更多还原

【Abstract】 Developing the emission inventory for mobile sources is the initiating step of motor vehicle emission control. This paper investigates vehicle activity data in Macao including vehicle population, vehicle types, vehicle registration distribution, and annual mileage accumulations. MOBILE5 and PART5 models were modified and used to calculate the emission coefficients of gaseous and particulate air pollutants from onroad motor vehicles. The total exhaust CO, NOx, HC, PM10 and PM2.5 from vehicles were 15 852 t, 2 416 t, 2 449 t, 141 t, and 128 t in Macao in 1999. The different vehicle contributions to the total vehicular emissions were estimated. The results show that motorcycles and gasoline passenger cars are the most important contributors to CO and HC. NOx and particulate matter control strategies need to focus on buses and heavyduty diesel vehicles.更多还原
