利用机动车排放模型测算颗粒物排放污染是建立机动车排放清单的基础,其中选择合适的模型进行本地化修正是保证测算结果准确性的关键。基于此,选取国内外代表性排放模型COPERT,MOBILE,IVE和MOVES,分别从车型分类,燃油品种,颗粒物粒径、来源、构成,时空分辨率和本地化修正难易多个方面对各模型的颗粒物测算能力进行了对比分析。以我国实际情况为参照,从模型应用于我国机动车颗粒物污染测算的角度总结了各模型的优缺点和适用范围。
Calculating particulate emission pollutions by using vehicle emission model is a base work for vehicle emission inventory establishment, and selecting one appropriate model for localized correction is a key to ensure the accuracy of calculation results. Based on this, four representative emission models, namely COPERT, MOBILE, IVE and MOVES were selected. Their particulate calculation ability were compared from aspects of vehicle type classification, fuel type, particulate size, origin, composition, temporal and spatial resolution, and localized correction difficulty. Considering the actual situation of our country, the advantages and disadvantages and application scope of each emission model were summarized from the aspects of applying these models to calculate vehicle particulate emissions in our country.
