Research On Space Structure Of Modern Typical Blocks In Harbin Based On Self-organization Theory

The promotion of new-type urbanization and the rapid development of urbanization have led to the phenomenon of large-margin land expansion,large-scale urban renewal and large-dimension architectural transformation in urban construction.Under the macro background of the urban construction,practical problems such as urban structural division,cultural fracture and environmental degradation are gradually exposed.The correct solution and mitigation of the status quo is related to the future construction and sustainable development of the city.At present,the domestic research on the spatial structure of historical blocks is static,phased,and top-down,lacking analysis of its dynamic,full-cycle,and all-round growth and evolution.This paper takes Harbin's typical historic blocks:Central Avenue,Gogol Street and Jingyu Street as research objects and makes innovation and optimization in theory and technology.Based on the self-organization theory,research methods such as Spatial Syntax Theory and Geographic Information System are adopted.This paper analyzes the spatial structure of the cycle-growth-evolution process of three historical blocks from the point-line-surface-body structure level,space environment-geographic environment interface level,economy-culture-society environment level.According to the level of city-urban-street-unit,the circulation system summarizes the cyclical law and extracts the circulation points of the structural system for the structural system,cultural context and node cells in the formation process of the initial historical blocks.From the three steps of biological perspective:the source of energy,the mode of organization and movement,and the process of division and differentiation,the gr owth process summarizes the growth rules of the order parameter extraction,the synergism and the competition in the development process of the historical blocks.Firstly,the model structure and parametric analysis of the point-line-surface dimension of the spatial structure of the mature historical blocks are carried out during the evolutionary phase.Secondly,the current space structure is analyzed in the equivalent way of attraction points,road network structure and block interface.Finally,a comparativ e analysis of structure,function,and environment is made and suggestions and strategies for improvement are proposed.The purpose is to trace the source of historical context,continue the factor of vitality growth,and improve the protection system of h istorical blocks by mining and parsing the spatial structure prototype of historical blocks.Providing practical and sustainable help and advice on the activation,utilization and organic renewal of historic blocks.
