| 摘 要： | 随着城市交通的快速发展,交通污染逐渐成为影响城市空气质量的主要因素。街谷内的交通污染还会因为室内通风对室内空气质量产生影响。本文介绍了城市街谷内交通空气污染的主要特点和扩散模式,总结了室外交通污染对室内空气质量的影响特点和影响因素,并对现有的实地测量法、理论模式预测法和数值模拟法进行了分析和比较,最终对数值模拟法可能遇到的问题和解决方法进行了分析和讨论。

| Abstract: | With the rapid development of the urban transportation,the traffic emission has been the main pollution source for the urban air quality.The pollution also impacts the indoor air quality(IAQ) due to the ventilation from the outdoor.The main features and dispersion models of traffic air pollution in urban street canyons are generally reviewed.The impacts of outdoor air pollution which include the gaseous pollutants and particulates on the indoor air quality are summarized according to the features and factors.Also comparisons and analyses are made for the methods of field observations and mathematical models.The pollutant concentrations are calculated by solving either analytically a set of parametric equations or numerically a set of differential equations that describe the wind flow and pollutant dispersion.The problems and suggestions on numerical models are presented. |
