| The Xisi historical block can be traced back to the construction period of Dadu in the Yuan Dynasty,which is an important material carrier of the development history of Beijing Old City.With the development of society,Xisi historic District gradually became depressed and lonely from the late Qing Dynasty and the early Republic of China.It has been faced with some practical problems,such as the damaged appearance of the district,low vitality and poor living environment.At present,it is urgent to protect and update Xisi historic District.In the past discussion of the Xisi historic district,the theoretical research and updating strategies are mostly based on traditional ideas,and few quantitative analysis of the "structural" characteristics of the block space.The self-organized activities of residents in Xishi historical District are very consistent with the spatial analysis and quantification of space syntax theory based on the "self-organized movement theory".Therefore,this paper studies Xishi Historic District based on the space syntax theory and analyzes it from the macro,meso and micro levels.In order to analyze its spatial characteristics by means of model construction and data analysis.This paper is divided into five chapters to carry out the research.The first chapter discusses the background of the topic,the purpose and significance of the research,defines the relevant concepts and summarizes the relevant literature at home and abroad to build the research framework.The second chapter combs the basic theory operation of space syntax and the general situation of Xisi District,which lays a foundation for the subsequent analysis of the spatial form of the district by using space syntax,and expounds the construction of space syntax and the three-level research system of Xisi District.The third,fourth and fifth chapters are the core chapters of this paper.They study the Xisi historic District from the macro city level,the middle street level and the micro building level respectively,including the evolution of urban spatial form structure of the district in the old city of Beijing from the Yuan to the present,the Visual analysis of the block,the convex space analysis of the single building,and the correlation analysis between thermal value and traffic flow measurement.The spatial morphological characteristics,conservation and renewal values and strategies are discussed respectively.The fourth part summarizes the analysis content of the full text and summarizes,at the same time puts forward the shortcomings of the research and further prospects. |
