夏热冬冷地区城市广义通风道规划探析——以武汉四新地区城市设计为例

Study on Grand Urban Windway Planning in Hot Summer and Cold Winter Area——Case Study of the City Design of Sixin Area of Wuhan

通过对夏热冬冷地区气候特征、城市热岛效应、城市环境与城市能耗的分析,从气候学、生态学、景观学与城市规划相互结合的角度,提出城市广义通风道的概念及其构成。在此基础上,借助于计算机城市风场模拟等实验手段,分析了大尺度、复合型城市通风道利用自然风和水体绿化的传输、蒸散功能,促进城市通风排热、缓解热岛效应、改善微气候的工作原理。以武汉四新地区城市设计为例,探讨了城市广义通风道的规划方法与实施策略。

With the analysis of climate characteristics in hot summer and cold winter area,urban heat island effect,urban environment and urban energy consumption,this paper states the concept of grand urban windway and its function and construction,from the view of integration of climatology,ecology,landscape and urban planning.Taking the urban design of Sixin Area in Wuhan as an example,the article discusses the planning methods of grand urban windway and its implemental strategies.
