| 摘 要： | 在分析长春市大气环境中NOx 污染源与浓度时间变化规律的基础上,对机动车尾气NOx 排放总量分担率、不同车型NOx 排放量分担率和NOx 浓度分担率进行了量化研究.结果表明,长春市机动车尾气NOx 排放总量分担率为34.8%,且呈逐年上升的趋势;重型柴油车和中型汽油车的分担率较高,居前两位;NOx 浓度分担率为38.41%,接近全国大型城市水平,市中心区域分担率水平很高.

| Abstract: | With the analysis on the pollution source and the change of NO_x concentration in atmosphere of Changchun City, the share rate of the gross quantity of NO_x, the rate of quantity of NO_x from different type of vehicles, and the rate of NO_x concentration were studied. The result showed that the share rate of the gross quantity of NO_x was 34.8%, this number was increased year after year. The share rate of heavy diesel vehicles and medium petrolic vehicles were higher than other kinds of vehicle. The share rate of concentration was 38.41%, which was close to the average level of big cities in China. The share rate in the centre of city was much higher than the other areas. |
