摘　　要：基于COPERT模型和MOVES模型的计算原理,利用车辆特征、气候、燃油等参数信息将蒸发排放因子细化,建立了热浸、运行、昼间、加油4类不同蒸发机制的排放因子数据库,并对国三、国四、国五、国六车辆进行了蒸发实车试验,与模型计算结果校验得知两者的总体变化趋势一致,数据较吻合。利用建立的排放因子库,结合各省市的汽油车保有量、活动水平等数据,计算得到2020年中国汽油车挥发性有机化合物排放总量约为51.42万t。在总的蒸发排放量中,加油排放是最大的贡献者,对总蒸发排放的贡献率为37.4%。Based on the calculation principle of COPERT model and MOVES model,the evaporative emission factor was refined by using vehicle characteristics,climate,fuel and other parameters.Evaporative emission factor databases of four different evaporative modes,i.e.hot soak emission,running loses and refueling loses were established.In addition,evaporating tests were carried out on vehicles meeting ChinaⅢ,ChinaⅣ,ChinaⅤand ChinaⅥemission standard.It can be found that the general trend of change is consistent with the calculation results of the model,and the data are in good agreement.With the emission factor database,combined with the total amount of gasoline vehicles and travel activities in each province,it was calculated that the total amount of volatile organic compounds emission of gasoline vehicles in 2020 was about 514200 tons.In the total evaporative emission,refueling loses was the biggest contributor,contributing to 37.4%of the total emission.
