Research On The Spatial Structure Of Traditional Blocks From The Perspective Of Flow Space

The innovative development of information technology has made social activities break through the limitations of geographical space.Human beings have entered a new era of high dependence on social networks,and the transformation of place space into networked dynamic space(flow space)has become a trend.The rapid flow of various elements in the flow space makes the spatial structure of the block and the representation of the constituent elements change.In the process of urban renewal,it is difficult to put forward a targeted block space optimization strategy if the spatial structure type of the block is not clear,which will lead to the decline of the spatial pattern of the block,the homogenization of material form and the disappearance of historical culture.As the basis of urban characteristic development,it is very important to realize the planning response of traditional blocks in the process of information society development.In this context,how to analyze the basic status of traditional blocks,how to analyze the characteristics of traditional blocks under the action of flow space,and how to study the spatial structure types of traditional blocks under the background of flow space have important theoretical and practical significance for realizing the adaptive development of traditional blocks.Based on the network text data,Baidu interest point data(POI)and field survey data,this paper explores the characteristics and spatial structure types of traditional blocks in the context of flow space from the perspective of flow network.Firstly,based on the background of flow space,the spatial structure of traditional blocks and the representation of their constituent elements are analyzed.On the basis of analyzing the constituent elements and characteristics of traditional blocks in Hohhot,traditional catering is taken as the representation element of traditional blocks.Secondly,the coupling analysis of the continuity,order and integration of traditional catering and the evolution,form and use characteristics of traditional blocks is carried out.The network text analysis method is used to analyze the information flow of traditional catering.It is concluded that the information flow of traditional catering can represent the characteristics of traditional blocks from three aspects : spatial characteristics,cultural characteristics and image characteristics,which proves the effectiveness of traditional catering to represent traditional blocks.Finally,based on the physical spatial data of traditional catering,a spatial network model with regional attributes is constructed.The social network analysis method is used to study the relevant indicators of spatial network,and three types of spatial structure of traditional blocks,namely,polar core endogenous,ring-type extension and decentralized group,are condensed.Three spatial structure optimization strategies are proposed to optimize the spatial configuration of ’node-node ’,enhance the correlation between ’ node-group ’,and strengthen the connection between ’ group-group ’.In general,combing the theory of flow space and the basic data of traditional blocks in Hohhot,taking traditional catering as the representation element of traditional blocks,and providing new ideas for the study of traditional blocks from the perspective of flow space.Analyze the characteristics of traditional blocks represented by the content of traditional catering information flow,and provide support for the study of regional characteristics of traditional blocks under the action of flow space.The characteristics of traditional catering space network are studied,and the spatial structure types of traditional blocks under the background of flow space are proposed to ensure the operability of spatial structure optimization and urban renewal.Studying the spatial structure of traditional blocks from the perspective of flow space can accurately grasp the new spatial rules and carry out adaptive planning response,so as to provide reference for domestic traditional block research and urban renewal work.
