Research On Spatial Morphology Evolution Of Main Urban Areas In Harbin Based On Space Syntax

Urban spatial form is not only the accumulation of City material space and historical culture in different periods,but also embody to solve the many problems of city society,economy,culture and environment,and constantly change with the development of the city.After the reform and open,China’s rapid development of urbanization,has brought in capital rapid agglomeration and growth of the urban population scale and at the same time,also brought the rapid expansion of land and urban spatial form and spatial structure of the disorder,which emerged the "transition of urbanization" phenomenon..So the research of urban spatial form evolution pattern,exploring the driving mechanism of the evolution and the evolution of mining depth problems has important significance for us to grasp the direction of city development,city characteristics and charm reshaping and improve the new urbanization quality connotation.Harbin,as the core city in the northeast region and the northeast North of the center of the city,which has experienced thousands of historical changes of context and centennial transition,has a series of problems,such as lack of power of economic growth,lack of vitality of the city and cultural influence declining,which restrictg the further development of the city.Based on the theory of urban spatial morphology,time and space as the clue and the spatial syntax as the main technical means,this paper expounds the inherent characteristics and basic laws of the development and evolution of the spatial form of the main urban area of Harbin by quantitative methods.Study of syntactic parameters is closely related with the city spatial morphology: Integration [HH],Integration [HH] R3,Intelligibility and Synergy ect,the study has nine different periods syntactic axis model of three time periods in main city of Harbin,and has a specific spatial location,which forms certain value and influence on the spatial morphology of Harbin main data base.Based on the axis model,by analyzing the changes of syntactic numerical,the research has a accurate syntactic assessment for Harbin urban spatial form evolution objectively.It includes the scale of the high centrality of streets is expanding,the structure of high centrality street network is becoming more and more stable,and the urban center collectivity turns to the west and the south.At the same time,further to the Harbin urban spatial form evolution of the connotation of characteristic analysis,including the use of compactness of "rolling wave" type change,understanding of "S" type change and synergy "sickle" type.In addition,the research has a summary for evolution law and driving mechanism of the spatial form of the main urban area.Finally,the main problems of the evolution of the spatial form of the main urban area of Harbin are summarized based on the research.So in order to optimize the spatial structure of the main city of Harbin,and to shape the unique and charming space form plays a corresponding role in guiding.
