摘　　要：如今,50%以上的世界人口居住在城市中,而城市由于其特殊下垫面及人类活动影响存在一些特有的环境与气候问题,其中最为严重和明显的是城市热岛效应及空气污染问题。为了缓解这些问题,本文提供了一种城市尺度着手的调节策略:城市通风道。在城市中设计通风道,有助于打破城市热岛环流帮助城郊凉爽气流渗入,提高城市内空气的流动性,增加城市绿化率,分割大面积城市空间,消除热岛的规模效应及叠加作用。本文浅析了城市通风道建立的必要性,对城市环境、气候的调节作用,给出了通风道设计的原则和设计策略,最后提供了一个简单的案例开拓研究思路。Nowadays, more than 50% of the world＇s total populations live in urban. Urban is greatly affected by people＇s activities and has specific environmental and climate problems. Urban heat island phenomenon and air pollution are the first two problems above all, which need to be solved emergently. To improve the thermal and wind environment of the city, urban ventilation corridor is introduced to urban planning in this study as the accommodation strategies in urban scale. Urban ventilation corridor can break the urban heat island circulation and help introduce fresh, cool air into the urban. It also can strengthen urban greening segregating construction and divide the vast area of urban to several pieces to decrease the scale effect of urban heat island. We give the proof of the necessity of planning urban ventilation corridor, and analyze the positive impact of urban ventilation corridor on urban environment and climate in this article. We also summarize some of the principles and strategies of the planning of urban ventilation corridor. At the end of this article, a study case of urban ventilation corridor planning is briefly introduced to give a new idea.
