| 摘 要： | 本文利用成都市城区近4年的环境空气二氧化氮浓度资料,结合成都市机动车保有量,分析了成都市机动车保有量的增加对空气中二氧化氮浓度的影响。分析表明,成都市机动车保有量的增加对空气中二氧化氮浓度有明显影响,尤以交通干道附近最为显著,二氧化氮浓度较非交通干线分别偏高12.0%～47.8%,成都市采取的高污染车限行等措施对二氧化氮浓度的控制起了重要作用。

| Abstract: | Based on the data of atmospheric nitrogen dioxide concentration monitored during the last four years and present number of vehicles in Chengdu City,the effect of increasing vehicles on atmospheric nitrogen dioxide concentration was analyzed.The results showed that the effect was significant,especially that near major traffic roads where the nitrogen dioxide concentration was higher that area else by 12.0%~47.8%.The measures to limit the high-polluting vehicles played an important role to control the nitrogen dioxide concentration. |
