基于GIS的武汉市街道汽车尾气扩散模式试验研究

Diffusion Mode of Automobile Emission in Wuhan Street Based on GIS

    摘要
  • 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。

     

    Abstract: With investigation of automobile flow,NO_(x) concentration and the meteorological features of Luoyu Road in Wuhan City,the characteristics of traffic flow and NO_(x) 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.
