摘    要:通过对具有街道峡谷特征的南京市中山路机动车的车流量污染物质量浓度和气象要素的调查与监测,了解到中山路机动车尾气污染物中CO,NO x的质量浓度与车流量有关,成正比关系,日车流量高峰时间分别在10:00,14:00和18:00。中山路环境容量分析是通过污染物扩散模型对CO,NOx污染物质量浓度模拟,其模拟结果和实测结果相近:CO质量浓度的模拟和实测结果比值在0.5,2]区间的比例为96%,NOx质量浓度的模拟和实测结果比值在0.5,2]区间的比例为80%,表明模拟结果有效。

关 键 词:南京市  街道峡谷  机动车  尾气污染  环境容量分析  扩散模型  空气环境监测

Abstract:Pollutant concentration and meteorological element of pollution of motor vehicle exhaust emission in streets with aspect of canyon were investigated and monitored. The mass concentration of CO and NO x in Zhongshanlu were related with vehicle flow, almost was direct proportion, the peak flow were in the time of 10, 14 and 18. Its environmental capacity analysis was made according to the concentration of CO and NO x with the model of pollution diffusion, the simulative result was similar to the real determination
Keywords:Motor vehicle exhaust emission  CO  NO  2  Diffusion model  Environmental capacity  Street canyon
