Micro-renewal of spatial form of Xizhou Ancient Town in Dali based on space syntax
To analyze the quantitative characteristics of traditional street and alley spaces,we take Xizhou Ancient Town in the historical town cluster around Erhai Lake as example,and use the Depthmap software of spatial syntax to construct an axial model and a viewshed model,so as to further measure global integration,local integration,legibility,viewshed connec-tivity,and viewshed integration,thereby exploring the research direction of quantifiable and optimizable street spaces.First-ly,we found that the main arteries of Xizhou Ancient Town have a high degree of integration,with the architectural structure presenting a pattern distribution of the shape"田",and the street and alley layout showing a pattern arrangement of the shape"井".The road network intersects with each other,with the most accessible locations concentrated on Shihu Street.Secondly,due to the dense alleys and unclear hierarchical structure of the road network in the ancient town,the overall spa-tial recognizability is not high,necessitating the improvement of the guidance system to enhance the comfort of the tour.Thirdly,alleys with traditional value are not easily accessible,and areas with good viewsheds are poorly planned,so the road system should be optimized to strengthen the connection between spaces.Finally,the paper summarizes the micro-renewal strategy based on quantitative measurement,and organizes the optimization strategy in the background of protecting and de-veloping historical and cultural ancient towns.
