夏热地区“常全影”空间设计时空分析体系

The spatiotemporal analysis system in the design for Constant-holistic Shadow space in hot summer area

为改善夏热地区夏季人群室外公共空间中长时间活动的热舒适性,构建“常全影”空间是一种有效的途径。但相关规划和设计阶段还须对设计形成的“常全影”空间与人群活动目标所需之间的符合度进行时空分析,以便设计进程可渐序推进并实现设计目标。文章解析了“常全影”空间的时空多样性、复杂性及其对设计过程的要求,阐明“常全影”空间设计时空分析的方式、对象、标准和特征,并建立了时空分析体系框架,为进一步探索系统的时空分析方法提供指引,以促进相关规划和设计有效构建“常全影”空间。

It is an effective approach to construct a Constant-holistic Shadow(CHS)space to improve the thermal comfort for people s long period activities in outdoor public spaces in hot summer areas.However,in the relevant planning and design stages,it is necessary to conduct a set of spatiotemporal analyses on the conformity between the CHS space formed by the design and the target one required for crowd activities,to gradually promote the realization of the design of CHS space into the design process.In this paper,the spatiotemporal diversity and complexity of CHS space and its requirements for the design process were analyzed.The mode,object,standard,and characteristics of spatiotemporal analyses in the design of CHS space were expounded.And then,a framework of the analysis system has been established.It guides further exploration of the system of spatiotemporal analysis methods,to promote relevant planning and design to effectively construct CHS spaces.
