城市规划与设计角度的城市小气候研究进展

城市小气候的改善是城市规划与设计中直接相关于人居生活的重要部分．本文从两个方面出发，分别综述了有关城市规划与设计要素对小气候的影响以及其改善小气候方法的研究报导，总结了相关规律和实际应用方法．目前城市小气候的界定尚不明确，主要集中在小尺度研究；城市规划与设计要素影响研究主要为各物质要素对温度、湿度、风及太阳辐射的影响；城市规划与设计改善小气候策略研究的方向较窄，且定量说明较少，主要为整体层面的组织方法：未来更为细分的专项研究，以及相关方面的定量研究是主要的方向．

Progress of Urban Microclimate Study from the Perspective of Urban Planning and Design

As an important part of urban planning and design, the improvement of urban microclimate is directly related to residential life. The paper reviews the researches about the effects of relevant elements of urban planning and design on mi croclimate and the studies of approaches to improve microclimate, and then summarizes relevant laws and practical methods. Focused on small scale research, the present definition of urban microclimate is still vague. The effect research of urban planning and design is mainly about the influence of material elements on temperature, humidity, wind, and solar radiation. The microclimate improvement strategy researches in urban planning and design are narrowlyoriented focused on the or ganization methods on the overall level, and are short of quantitative explanations. In the future, more specific and quanti tative studies are the main orientations,
