摘要
中国汽车工业的快速发展和汽车保有量的快速增长,带来了日益严峻的环境污染问题。国家通过及时制订和加严机动车污染物排放标准,使我国机动车污染减排取得了显著成效。自实施国Ⅰ阶段标准以来,新车单车污染物排放削减了57%～96%,带动了整体在用汽车平均污染物排放因子明显下降,有效控制了机动车污染物排放总量,使城市空气质量得到改善。通过分阶段不断加严汽车排放标准,污染物排放量呈逐渐下降趋势,总量减排效果显现。
The rapid development of automotive industry and the extraordinary growth of the vehicle population had brought about serious pollution problems in China.Through timely introduction of stricter emission standards for motor vehicles,vehicle emissions has decreased remarkably in China.Since implementation of China I emission standards,the emissions from each new vehicle had been reduced by 57%-96%.This has resulted in the decrease of average emission factors for the overall in-use vehicles,the effective control of the total emissions from motor vehicles and the improvement of the air quality in cities.Through implementation of strict vehicle emission standards in continual phases,emissions shows a downward trend,and a positive outcome of the total emission reduction is achieved.
