| 摘 要： | 综述了国内外机动车排放因子模型，基于开阔型、交叉路口型和城市峡谷型3类城市典型交通道路，探讨了各种机动车尾气扩散模式的优缺点和适用性。提出今后的研究重点是利用城市生态系统中的植物群落对汽车排放污染物扩散的阻碍和吸附，探索绿化植物对机动车尾气污染扩散的阻散特征；加强CFD软件在城市道路空气质量研究领域的应用；在GIS平台下，结合扩散模式开发环境综合管理系统。

| Abstract: | The emission factormodelsofvehiclesathome and abroad werereviewed based on threetypicaltypesofopen,intersection and urban gorgetraffic. Theadvantagesand disadvantageswere discussed on different vehicle exhaustdiffusion models. Theresearch emphasisin thefuture would beon the barriersand adsorption of vehicleexhaustpollutantsbyplantcommunitiesofurban ecologicalsystem and explorethe dispersion characteris ticsofvehicle exhaustpollution diffusion by green plants. Itmadethe bestofCFD softwarein research field of urban road airquality. In GIS platform,itwasdeveloped forintegrated managementsystem combined with the diffusion model. |
