基于空间句法的商丘古城历史街区空间形态研究

Research on Spatial Morphology of Historic Blocks in Shangqiu Ancient City Based on Spatial Syntax

文章以商丘古城历史街区为研究对象,立足于空间句法理论,为商丘古城历史街区构建轴线模型,借助Depthmap软件对商丘古城历史街区进行街巷空间的定量分析,通过整合度、选择度和可理解度三个量化指标视角分析发现:作为南北主街的中山大街,其整合度和选择度都非常高,可达性也很好,空间形态相对较集聚;散点图又表明历史街区的全局整合度和局部整合度呈显著的正相关,即意味着商丘古城街区基本是围绕着中山大街这条中轴线展开的。从长远看,这种空间形态是不利的,商丘古城的未来规划要更多向四周的街区扩散发展。

The paper takes the historic district of Shangqiu ancient city as the research object.Based on the theory of spatial syntax,the paper constructs an axial model for the historic district of Shangqiu ancient city,and conducts a quantitative analysis on the street space of the historic district of Shangqiu ancient city with the help of Depthmap software.According to the analysis on three quantitative indicators of integration,selection and comprehensibility,it is found that the integration and selection of Zhongshan Street,which is the main street between south the north,is very high.Its accessibility is very good,and its spatial morphology is relatively concentrated.According to the scatter plot,the global integration degree and local integration degree of the historic district are significantly positively correlated,which means that the whole ancient city is basically centered around the central axis of Zhongshan Street.In the long run,this spatial pattern is not conducive.The future planning of Shangqiu ancient city should be more diffused to the surrounding neighborhoods.
