Spatial Accessibility Of Shuidong Historical Block In Xuancheng City Based On Spatial Syntax

With the change of time,the historic district has formed a unique location,environment,spatial pattern and historical culture.In the past,the study of historical blocks often focused on the investigation of individual buildings and physical space,ignoring the "structural" value of the block space itself.Therefore,the theory of spatial syntax is used to describe the spatial relations and structures,and the mathematical model is used to describe and analyze the spatial reachability of Xuancheng Shuidong historical block quantitatively.The first part is the basic theory of the paper.This paper briefly describes the object,purpose,method and characteristics of the study.Aiming at the application of spatial syntax in historical blocks,this paper expounds the methods of spatial syntactic analysis and related variables,which lays a theoretical foundation for the subsequent analysis of examples.Secondly,it is the core part of the thesis.The analysis of the spatial accessibility of the historic block in the east of China begins with the comparison between the survey data of the distribution of people flow and the distribution of the reachability of the block space to verify its accuracy,and then through the road space and the building space.Node space of these three levels to carry out the analysis.Through the interpretation of relevant data,this paper aims to reveal the law of the evolution of block spatial pattern,to predict its future development trend,and to predict the deep and internal structural characteristics of street space,building space and node space.Finally,the paper summarizes the characteristics of spatial accessibility of historical blocks in East China,and analyzes the influence and mechanism of location and environment,historical evolution,location conditions,spatial pattern and immaterial culture on the spatial accessibility of historic blocks.Based on this,the paper puts forward some suggestions for optimization of road space,building space and node space in Shuidong Historic District.
