The Study Of Urban Renewal Based On "collective Memory" With Typology

L·Murnford defines city in his book of “the city in history” as “the place where the memory lies”.“Collective Memory” plays the key role in giving the historical meaning to urban physical form and forming the Genius loci.However at the time when the core of memory fades away,leaving the modern consuming space wrapped in historical physical surface,where is supposed to place the Genius loci of a city? The methodology of current urban renewal in China,having been proceeded since mid-20 th century,developing from the reckless massive demolishing and constructing to gradual renewing,and from “overriding” old urban renewal to a situation where the “fake-antique” blocks prevailing,is continuously causing the demolishment of the historical core of an old urban area.Therefore,exploring a form renewing methodology focusing on the revival of the “historical memory” and “the core of space” of old urban area is of much significance and urgency.This research discusses the urban renewal based on “Collective Memory” originating from typology within 4 aspects.Firstly,this thesis analyzes the current urban renewal status and the related background theories both in China and abroad,by which the research area is settled as well as its value,followed by the discussion of the objectives,the content and the methodology of the research.Next,by elaborating the related connotation of typological practice and “Collective Memory”,the thesis,based on the aspects such as the meaning of city,the city practice,regards typology as the method of the interpretation of “Collective Memory” to physical form.Through further analyzing,it is obtained that the city memory prototype(similar kinds)is the typological practice object of “Collective Memory” and then the typological analogy methods for “Collective Memory” prototype is proposed as well.Finally this chapter takes a step further in proposing the strategies of practicing in “Collective Memory” among urban renewal in China by comparing its features and objectives domestically and abroad,thus increasing the feasibility and adaptability of the research.In the third chapter,the thesis explores the typological thinking of city of Krill,Rossi and Moneo,through which the analogic method concentrating on the “Collective Memory” of city is summarized as follow: the “historical graphical analogy” of Krill,the “isomorphic analogy” of Rossi and the “space analogy” of Moneo.The “historical graphical analogy” emphasizes the restoring of urban space memory while the “isomorphic analogy” is more suitable for unifying the urban form context and the “space analogy” concentrates more on the symbol reconstructing of individual buildings to generate new Genius loci.This 3 categories of analogy have mutual relation with urban space renewal,urban form control and specific design of a building.In terms of the context of characteristic “Collective Memory”of China,the 3 categories of analogy vary in functionality and interact with each other,in which lies the potential helping develop a “Collective Memory” typological methodology aiming at urban form renewal,hence,leading urban memory onto a way of reviving and thus restoring the Genius loci of old urban space.In the fourth chapter lies the practical discussion including the “Collective Memory”of Luzu Temple Are and the practice of “Collective Memory” analogic method in this area.Based on the research on the historical transition and the fundamental current situation,the thesis obtained the elementary status and historical features in this area,based upon which the thesis further explores the origins of “Collective Memory” factors in order to decide the object to extract and the scope of “Collective Memory”,more specifically,Chongqing Yuzhong historical form and traditional town form in Bayu region.Based on the above,this thesis takes the establishment of the space connection and regional characteristic as the foundation,utilizing 3 categories of analogic method for deducting as well as restoring the “Collective Memory” of Luzu Temple Are from 3 perspectives as follow: urban space renewal,urban form control and individual building design,which has eventually accomplished the physical renewal and space reconstructing of Luzu Temple Are.This research studies and concludes urban renewal methodology based on topological “Collective Memory” from the perspective of adaptability,and detects its practical value during the progress of reviving memory and context in urban renewal.Finally the thesis discusses the practical value of the proposed methodology and its potential in further practice and research.
