| 摘 要： | 在研究太原市机动车污染现状的基础上,结合太原市机动车排放因子模型Mob ile6和污染物扩散模型OSPM的计算结果,在G IS平台上绘制了太原市冬夏两季道路机动车污染物排放强度分布图和道路交通污染物浓度分布图,并对可视化结果作了科学的分析,研究结果表明：（1）太原市冬季街道污染总体上要高于夏季,这种趋势以CO的表现尤为明显;（2）街道NOX小时浓度超标率比CO小时浓度超标率更高,在研究的56条路段中,CO小时浓度都没有超过国家二级标准,NOX小时浓度超标率达38.9%（夏季）;（3）NOX污染主要集中在中心区,而建成区周边道路某些路段污染也较严重。

| Abstract: | Analyzed the factual status of vehicle emission in Taiyuan and generated the spatial distribution diagrams of the exhaust strength and the dispersion concentration of motor vehicle pollutant on the GIS platform based on the databases from Mobile6 model and the OSPM model.In addition,the visual spatial distributions were analyzed scientifically.The results showed that.(1) The motor vehicle pollution in winter was more serious than that in summer generally in Taiyuan and this trend was particularly evident fo... |
