    摘要:

    通风廊道对于城市气候适应性提高以及人居环境品质改善具有重要意义,开展综述分析有利于对城市通风廊道研究进行系统梳理。既往综述研究过多强调通风廊道的理论框架、实践案例与规划编制,对通风廊道的构建方法及效应维度关注不足。总结了城市通风廊道的概念内涵、系统构成与研究进展,并指出其与城市风环境的关联,从微观与宏观尺度分别梳理了城市通风廊道的构建方法,归纳微观尺度方式为基于现状或模拟气流的观测,包括实地测量法、风洞实验法与计算机数值模拟法,宏观尺度方式为基于空间形态指标的通风路径测度,具体涵盖建筑形态指标选取、评价体系构建、空间路径生成3个步骤。研究也对城市通风廊道的效应维度、管控措施与规划实践进行概括,指出其效应维度主要聚焦于引风、降温、除霾,管控措施以指标预警方式为主,规划实践具有因地制宜的特征。未来研究应结合电路理论挖掘新的通风廊道构建方法与模型,从低碳与健康两个方面拓宽通风廊道效应维度,同时尝试利用多学科交叉的方式处理通风廊道研究尚存的矛盾争议。

    Abstract:

    Ventilation corridor is crucial to the improvement of urban climate adaptation and the quality of the human environment. A review is helpful to promote the systematic organization of urban ventilation corridor research. Previous review studies have focused on the theoretical framework, practice cases, and planning codification of ventilation corridors, with little attention to their construction methods and effect dimensions. First, this paper summarized the conceptual connotation, systematic composition and research progress of urban ventilation corridors and pointed out their association with the urban wind environment. Second, the study illustrated the construction methods of urban ventilation corridors at micro and macro scales, respectively. The micro-scale method was based on the observation of the current or simulated airflow, including the field measurement method, wind tunnel experiment method, and computational fluid dynamics (CFD) method. The macro-scale approach was based on the measurements of ventilation paths via spatial morphology indicators, which included three steps: the selection of architectural morphology indicators, the construction of the evaluation system, and the generation of spatial paths. Third, the study provided an overview of the effect dimensions, control measures, and planning practices of urban ventilation corridors. We pointed out that the effect dimensions mainly included wind diversion, cooling and haze removal, the control measures were based on the indicator warning method, and the planning practices were characterized by local adaptation. Furthermore, future research could combine circuit theory with new methods and models for constructing ventilation corridors, broaden the dimensions of ventilation corridor effects from low-carbon or health aspects, and try to utilize a multidisciplinary approach to deal with the contradictory controversies that still exist in ventilation corridor research.
