城市街道峡谷单侧自然通风研究进展

自然通风广泛存在于城市之中，了解城市自然通风建筑室内环境质量现状及存在的问题，是改善城市建筑室内环境质量的基础. 通过文献整理，首先研究城市街道峡谷中单侧自然通风的驱动因素，其次从建筑几何特征、通风能力、污染率、颗粒物浓度以及街谷设施等方面综述单侧自然通风的相关研究，最后提出建议. 研究表明，合理的展弦比、更好的城市布局以及精心的街谷设施设计能够最大限度地利用单侧自然通风，提升城市街道峡谷的室内环境品质.

Research progress on influence of unilateral natural ventilation on environment of urban street canyon

Natural ventilation widely exists in cities. To understand the current situation and existing problems of indoor environment quality of urban natural ventilation buildings is the basis of improving the indoor environment quality of urban buildings. Firstly, through literature review, the driving factors of unilateral natural ventilation in urban street canyons were studied. Then, the relative researches of unilateral natural ventilation were summaried from the aspects of building geometric characteristics, ventilation capacity, pollution rate, particulate matter concentration and street canyon facilities, and finally some suggestions for future research were puts forward. The results show that reasonable aspect ratio, better urban layout and careful design of street canyon facilities can take usage of unilateral natural ventilation with maximize effeciency and improve the indoor environment quality of urban street canyon.
