街道界面节奏的空间认知与量化研究

The Spatial Cognition and Quantitative Research on the Rhythm of Street Interface

针对街道界面虚实关系的认知问题,将街道界面的非实体构成元素定义为“隙”,由此提出“隙”的五种基本构型及界面节奏相关概念。结合空间知觉理论与心理物理学,尝试利用波形图的描述方法,建立“频率、振幅、稳定率”等参数关系,以认知视角展开对界面节奏整体差异性的定量描述。该量化方法可有效表征不同街道空间界面节奏的最主要特点,对于准确、便捷把握界面性状与行人空间认知的关系具有重要的研究和应用价值。

In view of the cognitive problem of substantiality and virtuality of street interface,this paper presents a virtual components of street interface-“gap”.It proposes five basic configurations of“gap”and the concept of street interface rhythm.With the space perception theory and psychophysics,it tries to use the description method of waveform and establishes parameters such as“frequency,amplitude,stability”etc.It also conducts the quantitative expression of the differences in street interface rhythm from the perspective of cognition.This quantitative method can effectively represent the main characteristics of the interface rhythm of different street spaces.It has important research and application value to grasp the interface characters and cog nition of walking activity.
