近年来，一些通风指标已被提出并应用于评估“城市室外通风”的效率，即城市区域通过城市冠层内部和上方之间的空气交换来稀释污染物、热量和水分的能力。本文以污染物扩散为重点，定义了室内初步提出和室外直接提出的13个通风指标。然后，选择了63项应用通风指数的文献研究（截至2018年出版），根据所研究的几何形状类型、每个指数的时间轴和使用频率以及所采用的湍流模型进行分析和总结。在分析研究成果的基础上，提出了各指标的优点和局限性，有助于科学界根据具体应用和目标选择最合适的指标。未来的前景也给出了，建议有必要将通风指标与城市形态参数，应用指数在真实的城市地区的特点是建筑物高度的变化和复杂的形态，以及提供阈值有用的城市规划的目的。
In recent years, several ventilation indices have been proposed and applied to assess the efficiency of “urban outdoor ventilation”, i.e. the ability of an urban area to dilute pollutants, heat and moisture by exchanging air between inside and above of the urban canopy. Here, focusing on the pollutant dispersion, the definition of 13 ventilation indices is given, which includes indoor-initially proposed and outdoor directly proposed. Then, 63 literature studies (published until 2018) applying the ventilation indices are selected, analysed and summarized in terms of the types of geometry investigated, the timeline and the frequency of employment of each index, the turbulence models employed. Based on the analysis of such studies, advantages and limitations of each index are provided, which may help the scientific community to choose the most appropriate one depending on the specific application and objective. Future perspectives are also given, suggesting the necessity to correlate ventilation indices with urban morphological parameters, to apply indices in real urban areas characterized by building height variability and complex morphology, as well as to provide threshold values useful for urban planning purposes.
