摘　　要：通过对南宁市天气、机动车数量、平均行驶里程等数据的调研,结合COPERT模型对南宁市机动车尾气排放因子进行计算,得出2014年南宁市机动车排放总量,并就机动车的速度、车型、燃料类型等特征与排放关系进行分析。结果如下:2014年南宁市机动车CO、NOx、VOC和PM的排放总量分别为94 689 t、40 942 t、32 873 t、1 822 t。其中排放CO和VOC最多的是小客车和摩托车,其贡献率达到了81.2%和80.6%;大客车和重型货车对NOx和PM有较大的贡献率,分别达到67.1%和91%。汽油车对CO和VOC有较大的贡献率,其排放贡献率为86.4%,NOx和PM的主要贡献率为柴油车,其贡献率分别为71.7%和91.4%。Through investigation of the weather, and amount, average mileage and other data of motor vehicles, combined with the COPERT model, the vehicle emission factor in Nanning City was calculated, the total emission in 2014 in Nanning was obtained, and relation between motor vehicle speed, vehicle types, fuel types and the total emission was analyzed. The results show that： CO, NOx, VOC and PM emissions in 2014 were 94 689 t, 40 942 t, 32 873 t, 1 822 t in Nanning city. Among them, CO and VOC were mainly discharged by passenger car and motorcycle, their contribution rates reached 81.2% and 80.6%. The large passenger cars and heavy goods vehicles had a greater contribution rate of 67.1% and 91%, respectively. Gasoline vehicles had a greater contribution rate for CO and VOC, the contribution rate of 86.4%, diesel vehicles had main contribution rate for NOx and PM, the contribution rate of 71.7% and 91.4% respectively.
