| 摘 要： | 根据机动车行驶工况和污染物排放系数测定，定量计算了近年来上海市机动车在实际行驶工况下的污染物排放量，匀速行驶时间仅占１３．８％，１９９５年机动车排放的ＣＯ、ＮＭＨＣ和ＮＯｘ负荷已占中心城区大气污染物排放总量的７６％，９３％和４４％，机动车已成为造成上海市区大气污染的主要排放源。

| Abstract: | On the basis of measuring and testing on vehicle driving pattern and emission factor, pollution load from motor vehicle in Shanghai proper has been calculated. The study results showed that the average speed of motor vehicle in the central city of Shanghai was around 10km/h, idle time was about 35.1% of total driving time and even time only 13.8%. The contributions of CO, NMHC and NOx from vehicle in Shanghai proper were about 76%, 93% and 44% of the total pollutant load from mobile and stationary sources in 1995. Motor vehicle emission is one of the major air pollution sources in Shanghai. |
