青岛市机动车排放源强与排放量研究

Study on Automobile Tail Gas Emission Strength and Emission Quantity in Qingdao

阐述了青岛市城市机动车的发展现状和道路交通状况,采集典型交通状况的车流量和车速数据,对评价区域进行了移动线源、面源的源强分析计算,得到了该区域内机动车排放网格数据,通过修正的排放因子计算了青岛市机动车主要尾气污染物的年排放量,目的是为机动车污染治理提供了理论数据。研究表明从排放源源强分析机动车道路污染状况和污染区域分布,不受扩散模式的影响,可以简单有效的评价机动车排放污染程度;青岛市城市主干道以成为机动车污染物的主要排放源,针对青岛市机动车尾气污染情况提出了合理的污染物治理建议。

The status of automobile and traffic was discussed in Qingdao, and the vehicle flux and speed data were also collected . The source intensity calculation of line sources and non - point sources in estimated area was done to get the grid data of automobile emission. Annual emissions of automobile tail gas pollutant were calculated using modified emission factors to provide reference to pollution control. The study result showed that based on emission source, the analysis on road pollution status and pollution region distribution was away from the influence of diffusion model intensity and vehicle emission situation could be effectively estimated. The main roads have become the primary pollution source in Qingdao. According to the results, several proposals were discussed.
