Study On The Composition Evolution Of Shenyang Central Spatial Based On Space Syntax

Since the century,the trend of the global economy is swift and violent,and the expansion of cities driven by economic development is unstoppable,which leads to the blind expansion of many cities and the appearance of many "pancake" urban space forms.Shenyang has an important strategic position in the Northeast Asian economic circle,the Bohai economic circle and the Northeast multilevel urban system.Shenyang is the capital city of Liaoning province and the important central city approved by the State Council.In the process of urbanization,the urban development of Shenyang also has some problems,such as the disorder of urban space expansion,the centralized development of the central region,the obvious agglomeration effect and traffic congestion.The spatial layout of multi center plus group is an inevitable choice to avoid the sustainable development of urban form.Spatial syntax is a hot method in the study of urban spatial morphology.Through quantitative modeling and analysis of urban spatial relationship and structure,the relationship between space organization and human society is studied.It is widely used in urban planning,architecture,landscape and other related disciplines.Through data,relationship diagram and model,the research and design of rational quantification have been realized,which provides a new way of work for urban construction work.The integration degree is an important syntactic variable which reflects the centrality of the space in the city.Through the analysis of the integration degree of the urban spatial form,the central space can be further analyzed.This article mainly studies the evolution of the spatial form of Shenyang city center.On the basis of the spatial syntax theory,application and the development of Shenyang City,the first is through the period of the pseudo Manchuria government(1932?1946 years),the liberation to the early reform and opening up(1946?1978 years),the early reform and opening up(1979?1996 years).In the period of economic transformation(1996?2010 years)and the period of urban-rural integration(2011),the urban street axis map of the five different periods of urban area has made a syntactic analysis of the position and shape of the central space;Secondly,in view of the changes of the central space in each period,the deep exploration is carried out,and the factors that affect the change of the center space are:the spatial depth of the structural road,the density of the street network,the connectivity of the region and so on,and how they affect the change of the space in the center of Shenyang;Finally,on the basis of the above research,the strategy of updating the central space form is put forward:correcting the zigzag road,widening the width of the road,building the three-dimensional traffic,building the slow traffic system,reforming the community street and lane space,and improving the connection between the center space and the surrounding area.
