Space Research And Protection Renewal Of Commercial Historic And Cultural Blocks

With the rapid development of the city,historical and cultural blocks as a precious historical fragment of the city,its protection and renewal has become an important research and practice in urban development.Commercial historical and cultural blocks are more closely related to social,economic,cultural and other factors.Reasonable commercial distribution and development is the main way for old streets to continue urban culture and stimulate vitality.This paper takes Nanchang Shengjin Tower historical and cultural block as the research object,through the collection of block commercial POI,flow of people gathering heat map and other large data and field survey and measurement of scale data,information feedback and other information,with Depthmap,ArcGIS,SPSS and other software platforms,The spatial syntactic axis analysis method,the kernel density estimation method,the buffer analysis method and the correlation analysis of mathematical statistics methods are used.From the macro,meso and micro levels: the old urban area of Nanchang,the Shengjin Tower district and the Shengjin Tower historical and cultural district,this paper makes quantitative analysis on the relationship between the road structure space and commercial agglomeration,the dynamic distribution of the users of the street space and the road structure space,the relationship between the commercial agglomeration and the study of the spatial form of the block,and makes a quantitative analysis on the protection and improvement of the block.The new measures are qualitatively analyzed.This article is divided into six chapters,the main chapters are:The first chapter,introduces the background of the topic selection,the significance and purpose of the research.According to the definition of the concept of commercial historical and cultural blocks,it expounds the relevant theoretical research at home and abroad from the perspectives of historical blocks and commercial blocks.The research methods and content of this paper.The second chapter,according to the characteristics of commercial historical and cultural blocks,defines the concept of commercial historical and cultural blocks and the spatial form and characteristics of the block,describes the structure of the block space and the structure of the commercial structure,and analyzes the typical research theory.The third chapter,describes the theory and basis of the analysis of the spatial shapeof the block,and proposes the quantitative thinking of the commercial historical and cultural block space.The fourth chapter,takes the Nanchang Shengjinta historical and cultural block as the research object,and uses the quantitative analysis idea to analyze the multi-factor correlation of the multi-scale space on the multi-scale,and draws the corresponding conclusions.The fifth chapter,through the conclusion of the analysis and the current situation of the neighborhood,puts forward the existing problems and protective renewal strategies of the Shengjin Tower in Nanchang.The sixth chapter,puts forward the conclusions and prospects of this paper.
