Research On The Regeneration Design Of The Traditional Block Of Yuhe In Bianjing Based On The Theory Of "Collage City"

Every traditional block is the collection of cultural essence of a city and a region.It embodies the cultural imprint of the historical era,and is a cultural thickening in a specific period.It has distinctive characteristics and cultural context that distinguishes itself from other regions.The traditional blocks both witness history and foresee the future;the regeneration of the traditional blocks is mainly based on two dimensions of protection and innovation.We must take the essence,remove the dross,develop in the protection and innovate in the development.At present,China has become the second largest economic power in the world,and the buildings such as Jinmao Tower,Shanghai world financial center and Shanghai center are all lined up.The square box type buildings with glass overcoat have risen from the ground,occupying the most skyline of the city,the city looks homogeneous and the identification is weakened.Meanwhile,during the 13th Five-Year,the registered residence relocation policy is fully liberalized,and the household registration is relaxed.The urbanization rate of population has reached 44.38% in 2019,and the city is seriously "overloaded".In this context,the overall urban planning is relatively lagging behind the pace of development of the times,the construction of public services and infrastructure such as road traffic,housing and water supply is relatively insufficient and backward,and the urban planning is blindly expanding,the land use efficiency is low,the layout is scattered,and the city is blindly radiating from the periphery.At the same time,urban construction only requires large regional area,complete industrial layout and wide functional coverage,regardless of proper functions,sound welfare supply,sufficient development power,protection of resources and environment,and inheritance of historical and cultural heritage,which leads to the occupation of a large number of cultivated land,the precarious red line of cultivated land and the loss of cultural heritage“ The "contradiction between man and land" is becoming more and more acute,which leads to the urban diseases such as the old residential areas,satellite cities,energy shortage,environmental pollution,disorder,high crime rate,and the decline of residents’ quality of life,which are wandering outside the modern urban management,out of the track of modern urban evolution,out of touch with urban cycle,losing ecological protection,in an unbalanced and disordered state and with low living standards It also leads to the lack of good protection of urban historical and cultural heritage,constructive destruction and "destruction while repairing",the lack of continuity of traditional blocks,and the lack of attention to cultural issues in urban construction.These problems lead to the increase of economic cost of urban construction and urban development,the huge waste of resources and the aggravation of demand contradiction.To a certain extent,it hinders the sustainable development of the city,hinders the continuity of urban gene and context,and hinders the evolution of the city towards more efficient,more inclusive,more stable,more characteristic,more dynamic and innovative direction.Therefore,the future of traditional blocks in the urban area has become an urgent problem related to the continuation of urban context and the inheritance of urban business card.The research scope of this subject is under the "planning","regeneration","transformation" and "optimization" design research of urban space environment and traditional blocks,hutongs and alleys.It is based on Colin Rowe’s "collage city" theory and "top-down" and "bottom-up" urban renewal models,and compared with the "symbiosis" theory in the ecological category and Mr.Wu Liangyong’s theory Based on the theory of "organic renewal" proposed by Professor Wu Mingwei and the principle of "systematic" old city renewal,this paper takes the revival of the traditional block of "Tianzifang" in Shanghai as an example to elaborate the paradigm of "collage" and "renewal and mending".Finally,based on the policy background of "ecological restoration and urban mending",it takes the overall spatial pattern of the traditional block as well as the urban skyline,street facade,and architectural design as an example The purpose of the study is to improve the coordination of landscape and architectural style,and to improve the public services and facilities of medical,education,culture and other cities.This paper analyzes the Renaissance and regeneration design and strategy of the Yuhe traditional block in Bianjing.
