The Conservation And Renewal Study On Social Network Of Chongqing Historical Area

Rapid urbanization process in the Construction of the historical region has made considerable progress, but there have been some problems poorly protected, embodied in the "emphasis on substance despise people, heavy economic and cultural development of light protection, light weight self-protection network protection, light weight quality " and so on. To solve these problems, the author attempts to jointly protect the historical area from the dominant form of matter and hidden social network, through the use of material science of spatial thinking urban and rural planning and social network analysis methods and principles of sociology, to discuss and resolve the historical area protection of physical space and form social networks.Firstly, by defining "historical area", "The Social Network" and "protection update" concept, to determine and analyze the typical study, from two aspects Summary "historic areas" and "The Social Network" the research status quo. Review of historic areas, mainly from phasing, the core concept, Practice and Methods of four points to start; from the concept of social network content, applications, urban planning and learning applications Comparison of four points to start a review, final review problems and make basic judgments.Secondly, it is the study of the history of the protection of Renewal areas of Chongqing. Based on the status of Historical and regional profiles, distribution and assess the main problem, the basic idea to build a social network protection; selecting research based on a sample of social network updates its material; and introduced the basic situation of eight study sample selected for provide a basis for follow-up study.Third, the social network model historic district of Chongqing Construction. Site research study selected eight samples were collected from the data according to the determined "point" and "line"; the collection of "point", "line" data into relational data, and binary data organized into an adjacent square; then use the SNA methods and principles, with Ucinet6.0 software platform to build eight social networks to study samples; and the initial characteristics of the sample area to determine the structure of social networks.Fourth, the structure of Chongqing Historical Area Social Network. Including the stability of the social network, vulnerability, structural balance and correlation analysis. Stability analyzes social network density, K- nuclear, Lambda and other indicators set; the number of cut-off point of vulnerability analyzes social networks and proportion; structural equilibrium analyzes the degree of centrality of social networks and the intermediate central potential; correlation analysis refers to the physical and social network updates are coupled analysis of the study sample. Finally, conclusions are summarized.Fifth, the social network for protection of Chongqing historic areas updating policies. Mainly from two levels, one is to protect the social network structure to update the study sample area, and increase the vulnerability of the balance of the three aspects of social network structure respectively, from the establishment of protected update policies to improve the social stability of the network structure, reduce social network structure; the second is based on physical form planning social networks, respectively, stability, vulnerability, structural balance and other indicators of social network structure based on guidance material form planning historic district.
