The Comparative Study On Spatial Image Investigation And Syntactic Analysis In Historical Core District Of Hengyang City

Research on urban form can be divided into the following categories: environmental behavior and psychology-based research methods, typology-based research methods and research methods led to the theory of group structures——Space Syntax.These three research methods, typology-based method for the study of traditional and modern inheritance relations in the field of architecture and urban planning, the angle is narrow, and more inclined to the author’s personal preferences, so do nottoo for this article.Environmental behavior and psychology-based research methods focus on the multi-domain, multi-disciplinary research, such as geographic information science, computer science perspective, viewing angle is more open, argumentation is more stringent.Meaningful, and we study the social awareness of the social individual.On the other hand, reflected by the cognitive map is essentially a subjective reflection of objective environment in the body.Although we can not deny the cognitive map from the elements or mode with a certain regularity, but we should be important is it more natural subjectivity.This subjectivity coupled with the impact of psychological factors for the cognitive map of the composition, content and functionality will have a positive or negative impact, thus affecting the accuracy of the conclusions.Space Syntax theory than other theories, a greater emphasis on the materiality of the space, independent of the regularity and initiative.Meanwhile, the Space Syntax Theory axis analysis, spatial analysis of the convex, depending on area analysis of these three major analysis research methods, plus the integration, accessibility, depth values, the degree of control the four maintechnical parameters, so this theory is also compared with traditional methods and ideas of urban design innovation.In addition, the space syntax theory and urban design methods to effectively combine, but also draw more objective, rational and intuitive findings, it can be said that space syntax theory is a more novel research methods.This thesis is based on the juxtaposition of the two research methods of cognitive theory and the theory of space syntax used interchangeably.Hengyang City is a typical small inland cities in the Historic Centre of the main object of study, while Kevin Lynch’s urban image theory and its classic cognitive map and questionnaire research Hengyang City, whilethe axis of the diagram of the historical city of Hengyang City, by space syntax theory and its supporting analysis software for syntactic analysis, statistics and comparison results of the two methods.On the one hand, by the space syntax theory to prove the cognitive theory, but also by the cognitive theory to prove the theory of space syntax, explore the intrinsic link between the two theories, on the other hand, the use of space syntax theory to enrich to make up for Kevin Lynch identifiedknow the theory of five elements each other fragmented enough.The complementary use of multiple research methods, in order to arrive at a more scientific, intuitive research.
