冬季低温地区道路移动源大气污染物排放清单

Emission Inventory of Atmospheric Pollutants from on-Road Vehicles in Low-Temperature Areas in Winter

研究了冬季低温地区道路移动源排放清单及污染特征.以长春市为例,基于测试和“道路机动车大气污染物排放清单编制技术指南”,建立了2016年全年的道路移动源大气污染物排放清单,利用ArcGIS进行空间分配,并基于IVE模型分析典型车辆启动排放贡献率.结果表明,长春市道路移动源CO,HC,NOx,PM2. 5和PM10年排放量分别为13. 17,2. 90,4. 09,0. 22,0. 24万t;小型客车和重型货车分别为CO,HC和NOx,PM10的主要来源;启动阶段,长春市典型车辆冬季启动贡献率高于上海市;另外,道路移动源排放强度呈现出由城市中心向边缘递减的趋势.

The emission inventory and pollution characteristics of on-road vehicles were studied in low temperature areas in winter.Taking Changchun as an example, and based on tests and the technical guide for emission inventory preparation of on-road vehicles, an emission inventory of Changchun was established in 2016.ArcGIS was used to allocate space, and the contribution rate of typical vehicles starting emission was analyzed based on the IVE model. The results showed that the annual emissions of CO, HC, NO x , PM 2.5 and PM 10 are 137 700, 29 000, 40 900, 2 200 and 2 400 tons, respectively.Minibuses are the dominant contributors to CO and HC, while heavy-duty trucks are the main sources of NO x and PM 10 .Meanwhile, the contribution rate during the start-up phase of typical vehicles in Changchun is higher than that in Shanghai.In addition, the emission intensity tends to decrease from the center of city to the outskirts.
