空间句法理论三维扩展之探讨

重点对空间句法进行三维扩展,旨在将空间三维向度的信息整合于传统句法之中,发展一种分析城市空间结构的三维新方法.研究从句法之本源空间认知角度出发,探讨建立三维空间句法的理论框架,并在此基础上构建三维空间句法的概念模型,提出加权集成度的概念进行句法三维扩展的计算,进而分别对此三维空间句法的理论与模型进行实验验证和分析计算.结论表明,扩展的三维句法模型更接近人们的空间推理与认知,加权集成度较集成度更好的描述与预测了人们在空间中的行为模式,三维句法提供了一种较传统句法更为精确的空间语言来定量描述城市空间结构.

Discussion about the Three-dimensional Extension of Space Syntax

The paper focuses on the extension of Space Syntax, aims to integrate the three-dimensional information into traditional space syntax, and develops a new three-dimensional approach to analyze urban space configuration. From the most essential spatial cognition of space syntax, the paper discusses to set up a theoretical framework of the three-dimension space syntax. Then based on the theory, a concept model of the three-dimension syntactical is constructed and the concept of weighted-integration is putted forward to calculate the mathematic model. In the end, three relevant analysis experiments are carried out to demonstrate and calculate the three-dimensional extension for space syntax. The conclusion indicates that the three-dimensional space syntax is close to spatial illation and cognition of people, and that the weighted-integration could describe and forecast the distribution of people's behavior in space better than the original concept integration. In a word, it is more accurate to use the three-dimension space syntax to quantificationally describe and grasp the urban configuration.
