Abstract Harbin-Changchun Megalopolis (HCM), as one of the vehicle production centers in China, has rapidly increasing vehicles on road supported by people’s increasing purchasing power, having directly and indirectly led to air pollution. This study systematically analyzes tempo-spatial characteristics of vehicle emissions by combining International Vehicle Emissions (IVE) model with the Technical guidelines for road motor vehicle emission inventory of air pollutants (Guideline) in HCM. This research further analyzes emissions from various emissions sources and projected emissions based on scenarios. The results show that the CO and HC emissions from mini passenger cars (MiniPC) and ordinary motorcycles using gasoline account for 86.4 % and 82.3 % of total emissions. Diesel-fueled heavy-duty trucks (HDT) are the main sources of NOX and PM, accounting for 86.5 % and 89.7 % of the total emissions, respectively. Three emission reduction scenarios are developed to analyze the vehicle emissions in HCM in 2020. This study concluded that phasing out the old vehicles is an effective strategy to mitigate air pollutions in HCM, with reduction rates of pollutants CO, HC, NOX, PM2.5 and PM10 being 19.8 %, 19.6 %, 8.6 %, 18.3 % and 18.8 %, respectively.

哈长城市群高时空分辨率车辆排放清单及减排策略

摘要 哈长城作为我国汽车生产中心之一，随着人们购买力的提高，道路上的车辆迅速增加，直接和间接地造成了空气污染。本研究将国际车辆排放（IVE）模型与 HCM 道路机动车辆排放清单技术指南（指南）相结合，系统地分析了车辆排放的时空特征。本研究进一步分析了各种排放源的排放和基于情景的预计排放。结果表明，使用汽油的微型乘用车（MiniPC）和普通摩托车的CO和HC排放量分别占总排放量的86.4%和82.3%。以柴油为燃料的重型卡车 (HDT) 是 NOX 和 PM 的主要来源，分别占总排放量的 86.5% 和 89.7%。开发了三种减排情景来分析 2020 年 HCM 的车辆排放。本研究得出结论，淘汰旧车是缓解 HCM 空气污染的有效策略，污染物 CO、HC、NOX、PM2.5 的降低率PM10 分别为 19.8%、19.6%、8.6%、18.3% 和 18.8%。
