Research On Space Design Of Metro Station Domain Based On Space Synatx

Subway is a secure and sustainable means of transportation with the maximum carrying capacity,the fastest development.The comprehensive design and utilization of urban public space based on subway stations in China is in its infancy stage.It is a problem worth thinking and studying to make subway stations interact well with the surrounding urban public space based on today’s public transport-oriented urban planning.In recent 20 years,Shanghai has witnessed rapid development of rail transit and relatively mature development of subway network.The research idea of guiding the transformation of urban spatial form and function through subway stations has also emerged.The concept of green development of urban transportation system,which supports urban space optimization with green transportation,organizes efficient urban operation,and meets the needs of urban activities at the lowest social cost,is being integrated into urban design and planning.Space syntax theory is a theory of sustainable management of urban development elements by analyzing the relationship between spatial relations and functions.It is also a method of processing data of urban design and architectural design by combining with computer-related big data analysis.Taking human behavior characteristics as the principle,it analyzes urban problems by establishing reasonable mathematical models,and provides a new angle and method for studying urban space problem.This thesis sorts out the common problems of the theoretical and practical research development of space syntax at home and abroad as well as the regional construction of subway stations,and proposes the optimization principles and strategies of space morphology of station domain based on syntactic analysis according to the theoretical thoughts of TOD.And then,from the perspective of empirical research,the station space of Shanghai Metro Line 4 is taken as the research object.Firstly,POI data of Shanghai were obtained to classify the vitality of subway stations of Line 4.Secondly,based on the segment analysis method of spatial syntax,this thesis analyzes and compares subway stations with different vitality through the relationship between space morphology and function.And then,it analyzes Metro Station Domain Space’s typical characteristics and puts forward the optimization strategy for the space design of subway station from the perspective of interdisciplinary research.What we should do is to promote the vitality of urban areas and the spatial environment of green travel mode and support the realization of various functions of the city,so that the traffic space is no longer only to complete the function of passing through,but to enable urban residents to know the city and enjoy the city in the station space.The thesis is mainly divided into the following four aspects:Basic research is to extract and analyze literature related to space syntax and subway station domain at home and abroad at present,and summarize the development direction of rail transit stations.First of all,this thesis is based on the research of subway station domain space under such a development background.It also expounds the theoretical research and practical application of space syntax up to now,analyzes the essential problems and application principles of space syntax discussed,and integrates more technical analysis and data support in the research,so as to improve the interpretation strength of space syntax analysis.Secondly,the strategic study deconstructs relevant construction practices or empirical studies at home and abroad,and constructs the research framework of spatial morphology of subway station from three aspects of theoretical basis,practical research and technical support,laying a solid foundation for the empirical study and optimization countermeasures of Shanghai Metro Line 4 in the following paper.Thirdly,empirical research is the core of this paper.The existing classification methods of subway stations are sorted out and the stations of Shanghai Metro Line 4 are sorted out.Then,according to the analysis results of POI data of different types of interest points,the active intensity was graded,and two stations with high active intensity,medium active intensity and low active intensity were selected respectively.After that,the visualization expression of GIS and various spatial analysis are used to improve the visualization degree of data,and the multi-dimensional empirical research on the spatial form of subway station domain is carried out from different spatial scales.This thesis makes an in-depth analysis of the current characteristics and existing problems of the research objects,and tries to explore the internal law of the dynamic development of subway station space by using the space syntax theory,so as to provide empirical research for the next step of putting forward the optimization strategy of station space.Fourthly,the application of strategy is an important extension and expansion based on the above empirical research.According to the functions and characteristics of subway station space,this chapter proposes relevant optimization countermeasures to construct subway station domain space highly compatible with urban public space.Through the construction of station space,the traffic node and urban node are integrated,and the optimization proposal of stimulating the vitality of surrounding urban area with subway station as the core is put forward.
