摘要
为了持续改善成都市空气质量,强化城市机动车排放管控,在成都市高分辨率机动车排放清单的基础上,通过对高排放车辆出行情况进行分析,考虑管控时间段、管控车辆、管控区域设置不同的低排放区限行措施情景,并计算减排量及减排比例。结果表明成都市区内国Ⅰ、国Ⅱ排放阶段机动车及国Ⅲ排放阶段柴油货车出行频次较低,在绕城(含)及高新南全天限行国Ⅱ排放阶段以下汽车以及全天限行国Ⅲ排放阶段柴油货车下NO_(X)、CO、PM_(10)、PM_(2.5)、VOCs各项污染物年度减排量分别能够达到0.84、2.35、0.05、0.05、0.49万t,减排比例分别达到13.0%、16.0%、20.0%、20.0%、13.0%,通过划定低排放区限制国Ⅰ、国Ⅱ排放阶段机动车及国Ⅲ排放阶段柴油货车在成都市中心区域行驶有较好的减排效果。
To continuously improve air quality in Chengdu and strengthen control over motor vehicle emissions,in this research,the travel patterns of high⁃emission vehicles were analyzed in this paper based on a high⁃resolution motor vehicle emission inventory of Chengdu.Different traffic control scenarios in various low⁃emission area are set by considering different control periods,controlled vehicle types,and traffic control areas,with emission reductions and reduction percentages calculated.The results indicated that motor vehicles of China's Stage Ⅰ and Stage Ⅱ vehicle emission standards,as well as diesel trucks of China's Stage Ⅲ vehicle emission standards have relatively low travel frequencies within Chengdu urban areas.In Chengdu Ring Expressway and High⁃tech South Zone where motor vehicles of below China's Stage Ⅱ emission standards and diesel trucks of China's Stage Ⅲ vehicle emission standards are not allowed to drive through all day long,annual emission reductions for various pollutants,including NO_(X),CO,PM_(10),PM_(2.5),and VOCs,amounted to 8400,23500,500,500 and 4900 tons,respectively,with corresponding reduction percentages of 13.0%,16.0%,20.0%,20.0%,and 13.0%,respectively.These findings suggested that designating low⁃emission areas to restrict the travel of Stage Ⅰ and Stage Ⅱ motor vehicles and Stage Ⅲ diesel trucks in the urban area of Chengdu can have significant emission reductions and effectively improve air quality.
