【摘要】：疏港卡车作为港区重要排放源之一,同时又是港区与城市联系的桥梁,其大气污染物排放成为近期学者研究的热点。以港口城市为边界、以疏港卡车为研究对象,通过分析整理国内外文献,结合实际调研结果,利用疏港卡车在港与在疏港大道的活动强度、排放因子与车辆保有量,构建基于活动量的沿江(河)港区疏港卡车排放清单编制方法以及本地化大气污染物社会成本标准。以南京港龙潭集装箱港区(NPLC)疏港卡车为例进行实证分析,结果表明:(1)疏港卡车大气污染物排放中NOx占主导地位,以疏港大道为节点时年排放57 t;(2)疏港卡车是港区CO_2排放首要贡献源;(3)边界的选择对排放量影响较大;(4)疏港卡车大气污染物总社会成本估算为1 992 292美元/a。在对研究结果及成因进行分析和讨论的基础上,提出疏港卡车减排建议。
[Abstract]:As one of the important emission sources of port area, truck is also a bridge between port area and city. The emission of atmospheric pollutants has become a hot spot of recent scholars, taking port city as the boundary. Taking the open port truck as the research object, through the analysis and collation of the domestic and foreign literature, combined with the actual investigation results, using the open port truck in the port and in the open port road activity intensity, emission factor and vehicle ownership. Based on the activity quantity, the method of compiling truck emission inventory and the social cost standard of localized air pollutants in the open port area along the Yangtze River (River) Port are constructed. The case study of open port truck is carried out. The results show that NOx plays a dominant role in the air pollutant emission of open port trucks, and the annual discharge is 57 t when the open port road is the node. (2) truck is the main contribution source of CO_2 emission in port area; (3) the choice of boundary has a great influence on the emission; 4) the total social cost of air pollutants in the truck is estimated to be US $1,992,292 / a. Based on the analysis and discussion of the research results and the causes, the paper puts forward a proposal to reduce the emissions of the truck in the open port.
