摘　　要：运用GPS和OEM收集了武汉市主要道路上的车辆行驶与实时排放数据。得到了武汉市机动车平均排放因子。根据车辆参数信息和行驶信息,运用CMEM模型模拟了武汉市机动车微观尾气排放,并与实测数据进行了对比。数据分析表明,用CMEM模型计算的武汉市机动车实时排放数据与实测数据总体趋势是一致的,并对CMEM在武汉市的适用性和应用进行了探讨。The real time data of mobile emission and vehicle information were collected with GPS and OEM. The average emission factors of Wuhan were determined. According to the parameters and operational information of experimental vehicles, the mobile emissions of Wuhan City were simulated with CMEM model and compared with the metrical data. The result analysis shows that the output of CEME model keeps with the trend of metrical data. Finally, the applicability of CEME model for Wuhan City was discussed.
