Nitrogen oxides (NOX) from vehicle, as one of the main sources of NO, in atmosphere, have a significant effect on urban air quality. Vehicular NOX emission inventory of Hangzhou was established in 2010 and the increased emission of vehicular NOX during 12th Five-Year Plan was also predicted. Then NO* emission reduction potential was analyzed under three scenarios: the current management, improvement scheme and strengthening scheme. The results showed that vehicular NO, emission of Hangzhou was 44300t mainly from heavy trucks which contributed to 34.1%. Vehicle population will increase 22000 with 1960t NOX emission increment in 2015. Scenario analysis revealed that improvement scheme including eliminating old vehicles and using better oil could reduce NOX emission 7460t with a reduction rate of 16.84%. And hybrid vehicle usage and alternative energy replacement will reduce NOX emissions greatly.%以杭州市为研究区域,建立2010年机动车NOx捧放清单,预测杭州市“十二五”期间新增机动车NOx捧放量,并设定了“现行管理”、“改善方案”和“强化方案””3个机动车管理情景,对NOx的减排潜力进行分析.结果表明,2010年杭州市主城区NOx捧放量为4.43万t,其中重型货车所占比例最大,为34.1％.“十二五”杭州市机动车将增加22万辆,新增NOx排放0.197万t.执行“改善方案”—机动车淘汰工程和油品替代工程,可减少NOx排放0.746万t,削减率为16.84％.增加混合动力公交车和新能源汽车的市场占有率可以提高NOx的减捧潜力.
