摘要
通过对武汉市珞喻路路段的车流量、NOx浓度和气象要素的调查与监测,分析了车流量特征和NOx分布特征,并用街道峡谷扩散模式进行了模拟。在此基础上,结合GIS描述了城市汽车尾气扩散模式,并在利用GIS及二次开发的条件下动态、直观地反映污染的时空分布规律。
With investigation of automobile flow, NOx concentration and the meteorological features of Luoyu Road in Wuhan City, the characteristics of traffic flow and NOx distributing are analyzed, and are simulated by use of the street canyon diffusion mode. Based on that, the diffusion mode of city automobile emission is depicted integrating GIS, and by use of data-base or second empolder of GIS, the distributing laws of space time about pollutant arereflected straightly and dynamicly.
