The Study On The Renewal Of Urban Old Industrial Site Based On The Theory Of Urban Catalyst

Since the industrial revolution, with the rapid development of economy and society, there is the reverse tendency of industrialization and urban old industrial sites in the inevitable.In the urban renewal, with the city industrial transformation and restructuring of the background, the renewal of urban old industrial site becomes a focus of attention, however the present renewal of the urban old industrial site is facing demolition and reconstruction of the revolutionary. This way leads to a destruction of the unique historical context of the urban old industrial site, the low city identification, and cause a series of social,economic,environmental and other issues.In this paper, the author introduces the urban catalyst theory, as a theory of urban design,through the election of catalyst or the implantation of original elements, without changing itsbackground connotation, through the shape of small scale catalyst effect of part, progressivedynamic updates, and thus lead to a wider range of urban linkage effects, in order to enhance the urban renaissance. Because of its location, culture, economic value,the renewal of urban old industrial site should start from the city level,in order to promote the integration of society、 economic and culture in the city,which provides a good opportunity for the author to study the renewal of urban old industrial site by using the urban catalyst theory. This paper attempts to study the specific means and strategy of the renewal of urban old industrial site under the guidance of the urban catalyst theory, so as to promote the revival and development of city society, economy, culture and so on.The author mainly from the five parts to carry on the writing and research.The first part is the introduction, mainly introduces the research origin and the background,the purpose and significance of the research, definition of related concepts, research at home and abroad, the research methods and framework.The second is research and analysis, put forward some problems. Through the study of elements and characteristics of the urban old industrial site, the investigation and analysis of current situations in the urban old industrial site were summarized, and the author put forward the problems and analysis the necessity of renewal of urban old industrial site and the renewal value. At the same time there are investigations and analysis of current situations of the renewal of urban old industrial site.And summarizes the existing modes and problems of the renewal of urban old industrial site, as the starting point of this paper, which paves the way for the following research.Again is the application part of the theory, including the third chapter and the fourth chapter. The third chapter introduced the urban catalyst theory,elaborated the concept and basic thought of characteristics,catalyst type, action principle and operation mechanism,and has carried on the summary of the related research; The author conducts a feasibility analysis and theory application between the urban catalyst theory and the renewal of urban old industrial site in the fourth chapter. The feasibility analysis of the two party, specific research on the dilemma of the renewal of urban old industrial site, the feasibility of the combination of the urban catalyst theory and the renewal of urban old industrial site, the significance of the urban catalyst theory, as well as the Introduction of practice cases of the two combination. In the application of the theory, the anthor puts forward the principle of catalyst, catalyst factor, the application of catalyst angle, the application of catalyst mechanism strategy and catalyst target.The fourth part is the part of the design strategy, is the core part of this paper, under the guidance of the urban catalyst theory,proposes the operation mechanism and strategy of determining the original point of catalyst, shaping the catalytic media and building the catalytic effect in the urban old industrial site. In the step to determine the original point of catalyst, analysis the original point on selected based on the conditions, put forward the the specific strategies of the construction entity, public space and the adaptive adjustment of the function as the original point of catalyst; In the shaping of catalyst media step, respectively from the view of space media, entity media, culture media and landscape media, point out the specific strategies and methods on the three-dimensional design in space, the old building reuse, context continuation of catalyst type,and the construction of complex three-dimensional landscape; In the shaping of catalyst effect steps, propose the catalyst type elastic design, catalyst environment of the site,and construct catalyst contact of the surrounding.Finally is the design of practical application,takes the China Germany joint teaching——the renewal design of urban old industrial site in Dusseldorf as an example, discusses the practical application of the design strategy of the renewal design of urban old industrial site, in accordance with the design strategy steps put into the practice application.
