摘要
柴油汽车排放是目前城市大气污染的重要组成部分,如何结合区域差异建立柴油汽车排放清单是制定相关减排政策的基础工作.首先按照使用用途将柴油汽车划分为7种车型,选择国Ⅲ 、国Ⅳ、国Ⅴ共3种排放标准的车辆得到基础排放因子;具体分析不同区域的柴油汽车排放相关影响因素及修正权值,包含环境参数、车速分布、载重系数及劣化系数;结合修正参数建立柴油汽车综合排放因子计算公式及城市柴油汽车排放清单计算模型,以淄博市为例完成了城市柴油汽车排放清单的建立.研究结论表明,本文提出的柴油汽车排放清单建立方法,适用于结合不同城市的环境特征、车辆特征和道路特征定量评价柴油汽车污染排放状况,并为制定具体的柴油汽车污染物排放控制政策奠定基础.
Diesel vehicle emissions are an important component of urban air pollution, combining with regional differences to establish diesel emissions inventory are important in the formulation of emission regulations. First, according to the intended use of diesel vehicles, we divide diesel vehicles into seven types.Then, we chose national emission standard Ⅲ、Ⅳ and Ⅴ to get basic vehicle emission factor. By analyzing different emission factors about diesel vehicles, which contains environmental parameters, speed distribution,load factor and deterioration factor, we finally get diesel comprehensive emission factor calculation model and city diesel emissions inventory calculation model. It is the two calculation models that let us finish the establishment of diesel emissions inventory for the city of Zibo, in China. The research shows that the methods for the establishment of diesel emissions inventory are suitable for environmental characteristics of different cities and diesel vehicle characteristics. It lays the foundation for the development of specific diesel vehicle emissions control policy.
