摘　　要：在对CALINE4模式进行参数修正和模型验证的基础上,对长春市主要街路的日均ρ(CO)进行了模拟,得出了长春市机动车线源污染的空间分布特征。结果表明,长春市道路交通CO污染严重的区域主要集中在一环路以内。On the base of parameter modification and model verification for the CALINE4 mode, the daily-averaged CO mass concentrations at the main streets of Changchun City were simulated, and the spatial distribution characteristics of automobile linear source pollution in Changchun obtained. The result revealed that the severe areas of CO pollution derived from urban traffic were mainly concentrated within the first-ring road.
