【Abstract】 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.更多还原
