'十二五'机动车氮氧化物减排对策初探——以南京市为例

摘要

诸多研究表明,机动车作为氮氧化物的主要贡献源之一,对城市大气环境的影响十分明显,以南京市第一次全国污染源普查的相关数据为基础,对南京市机动车氮氧化物的排放量进行了核算,并从机动车淘汰工程、机动车油品替代工程2方面对机动车的氮氧化物减排潜力进行情景分析,以期为南京市机动车氮氧化物的减排工作提供对策和措施.%Many studies have shown that as one of the main source of nitrogen oxides emission, vehicle exhaust gas has a significant effect on urban atmospheric environment.Base on the datum of China Pollution Source Census, this paper calculated the vehicular nitrogen oxides emission of Nanjing and analyzed the vehicular nitrogen oxides emission potential from two scenarios: eliminating of substandard motor vehicles and using better gas.This paper looks forward to provide some countermeasures for vehicular nitrogen oxides emission reduction in Nanjing.
