Adjustment Research On The Spatial Pattern Of Blocks In Harbin From The Perspective Of Urban Repair

Blocks are the basic units of urban space formation.After the reform and opening,China has continued to carry out an unprecedented and large-scale urban development.Due to the lack of historical experience,both urban planning and urban management are in a state of exploration.At present,China's urban planning has entered the stock planning stage from the incremental planning stage.With the slow expansion of the urban construction boundary,the focus of urban construction has gradually shifted from the outside to the inside,and more and more old blocks are facing rectification and renovation.In the past,the method of large-scale demolition and large-scale construction has been unsuitable for the development of today's cities.At this time,urban redevelopment as a renewed concept has received wide attention from all parties due to its low-impact and refined characteristics.As a space carrier for urban activities,the blocks are prone to problems such as unreasonable spatial organization and incomplete functions in rapid urban development.These issues will become more prominent with time,and therefore need to be resolved.To improve the above problems,this study conducted an in-depth analysis of the development and influencing factors of spatial patterns of urban blocks from the perspective of urban design,with a view to providing strategies and suggestions for the adaptation of spatial patterns of urban blocks in Harbin,and at the same time providing a study of spatial patterns of urban blocks in the future for reference.This article takes the urban refinishing as the basic perspective and uses the methods of literature review,empirical investigation,and time comparison to sort out the relevant research status and basic theories of urban street spatial patterns and analyzes the spatial form of the Harbin block from the aspect of urban design.The development is divided into four periods: the beginning of the city,the period of Japanese occupation,the period of a planned economy and the period after the reform and opening.It summarizes the influence of natural conditions,historical background,social environment and other factors in the process of the formation of the Harbin blocks,and the spatial organization and function layout features and other aspects summarize the existing problems.Finally,this article presents the research results of spatial patterns of blocks in Harbin.Based on historical data and empirical research on the causes and existing problems of the blocks,taking urban rejuvenation as the basic perspective,they propose adjustments and adaptations from the perspective of the spatial organization of blocks,the functional layout of blocks,the characteristics of blocks and the vitality of public space.The purpose of this paper is to improve the spatial design of the urban design,to integrate the functions of blocks,to create a coordinated street appearance,and to build a vibrant public space.The important role of urban design in the development of the blocks are to make the space environment of the block conform to the user.Demand highlights the value of street space patterns in urban development and social life.
