| 摘 要： | 随着全球城市化进程的不断深入, 城市高架道路密集出现. 这在一定程度上缓解了城市的交通拥堵, 但也带来了一系列交通污染问题. 通过文献调研, 对城市高架街谷交通污染物的扩散规律进行分析. 首先, 对城市高架街谷的交通污染特征及其建成环境特征进行梳理; 然后, 从空间尺度(水平和垂直)和时间尺度(宏观和微观), 对城市高架街谷交通污染物的时空分布规律进行归纳; 最后, 总结了交通、建成环境以及微气象环境等因素对交通污染物在高架街谷扩散规律的影响. 通过对城市高架街谷交通污染物的扩散规律进行分析, 以期对未来的相关研究提供参考.

| Abstract: | With urbanization rapidly spreading worldwide, viaduct have appeared in many cities. Although such roads materially reduce traffic congestion, they also inevitably increase traffic pollution. Hence, we aim to investigate the dispersion of traffic-related air pollutants (TRAP) in street canyons with viaduct. We will first delineate the characteristics of traffic pollution and built environments in street canyons with viaduct. Next, we will analyze the spatial and temporal distribution of TRAP in street canyons with viaduct on spatial (horizontal and vertical) and temporal (macro and micro) scales. Finally, we will summarize the influence of factors including traffic, built environment, and micro-meteorological environment on TRAP dispersion in street canyons with viaduct. We expect that these investigations will enhance our knowledge of TRAP characteristics in street canyons with viaduct, which will be of significant relevance to mitigate TRAP in streets and urban areas. |
