摘　　要：城市通风廊道与建成区的环境质量息息相关,并且是缓解城市热岛效应和改善居民健康的重要空间管控工具。在国土空间规划背景下,基于地理设计的方法论进行城市通风廊道的分析与规划已经成为重要的理论和规划实践的研究热点。文章以北京市六环内区域为例,通过建立地理设计模型,利用RS和GIS技术综合分析建筑、道路、水系、公园绿地等方面的数据,基于热岛强度数据、地表粗糙度、建筑环境、主导风向确定作用空间和补偿空间,并在此基础上构建通风廊道,以期为国土空间规划提供地理设计方法,从而更好地改善北京市生态网络空间环境。Wind corridor in a city is crucial to the environmental quality of built up area,and it is an important spatial governance tool that eases hot island effect and improve urban health.In the context of national territory spatial planning,geographical design based wind corridor analysis and planning has become a focus issue in theory and practice.With Beijing as an example,the paper sets up a model of geographical design,uses data of roads,building thermos,water system,parks through remote sensing and GIS,specifies functional and compensation spaces based on urban heat island intensity,ground surface roughness,building environment,prevailing wind direction,and eventually establishes wind corridors.The result shows that geographical design method may establish models of evaluation,change,impact,and decision making,and effectively guides wind corridor planning.It provides a positive geographical design exploration for national territory spatial planning,and sets a foundation for the improvement of ecological network in Beijing.
