应用CALINE4模式模拟机动车排气污染的时空分布——以厦门市主干道路为例

Spatio-temporal distribution simulation of vehicle exhaust pollution using CALINE4 dispersion model——taking the main streets of Xiamen as an example

研究了机动车污染扩散模式,以厦门市机动车污染排放实际数据为基础,结合具体的气象特点,采用CALINE4模式模拟了厦门市CO、NOx的一次浓度空间分布以及年均浓度空间分布,并对厦门市机动车污染的一般特点进行分析.

Based on factual status of vehicle emission and special geographical and meteorological conditions of Xiamen, spatio-temporal distribution of annual average CO and NO_x concentration was simurated using CALINE4 dispersion model in the urban region, and analyzed the vehicle exhaust pollution rule inXiamen.
