| 摘 要： | 以济南城市道路为研究对象,采用美国环保署AP-42模型和方法,通过道路分类、优化布点、样品采集、实地观测和计算分析,获得道路粉尘负荷及四种类型道路扬尘的排放因子,探讨了排放因子的主要影响因素。结果表明,路面粉尘负荷随车流量增大而逐渐降低,城市城区路面粉尘负荷多小于城市外围路面,且外围道路路面粉尘负荷随时间和空间变化大;支路和次干道排放因子相对较小,快速路排放因子较高,主干道排放因子最高,其TSP、PM10、PM2.5排放因子分别高达25.239 3 g/VKT、4.731 1 g/VKT、0.597 2 g/VKT;排放因子随平均车重增加呈现逐渐增大趋势;同种类型道路排放因子均随道路粉尘负荷的增加而增加;次干道和快速路排放因子随车流量增大而减小。所获结论可为城市道路扬尘排放估算提供参考。

| Abstract: | This paper introduces an application of USEPA’s AP-42 Model and the relevant methods to estimating road fugitive dust in Jinan.The roads in the city are classified into four types,and through calculation and analysis dust loading and dust emission factors which refer to TSP,PM10 and PM2.5 are estimated respectively.The influencing factors that affect the emission factors are also discussed.The conclusion of the study could provide useful information in the estimation of the city’s road fugitive dust. |
