Research On The Urban Renewal Planning Of Downtown In Period Of Rapid Developing

In China, transformation of economic development mode, adjustment of industrial structure and the acceleration of urbanization will greatly promote the development of urban renewal. At present, renewal research on central district of urban area focuses on local sections and is deficient in macroscopic planning. Blindness and arbitrary construction behavior still exist during the process of transformation of the old city. Based on the establishment and operation research on the urban renewal in macroscopic level, this paper attempts to offer evidence for urban renewal and redevelopment of central district.Firstly, this paper analyzes the main characteristics and development background for spatial pattern of central district of urban area in the background of rapid development period. Then summarize the problems and the sustainable development mode to form the primary theory foundation.Secondly, on the basis of theoretical analysis, through the following three aspects-economic, social and spatial morphology research on the essential influence of urban renewal in the development of urban spaces, combining the practice of Tianjin city centre, a new research orientation is put forward, which is promoting modern service industry, improving resident condition of people with low incomes and shaping modern culture of urban area.Thirdly, taking Tianjin city center as an example, through the analysis of promoting effect of urban transportation on urban renewal, coordinating development between urban renewal and transportation system is proposed. At the same time, in view of the problems and opportunities of protected areas during urban renewal, approaches are put forward about coordinative mechanism between urban renewal and reservation of protected areas.Finally, based on the research on orientation and methods of urban renewal, updating and perfection of transportation system, renovation and redevelopment of protected areas, The preparing method and operation model of special-purpose land use planning for urban renewal in metropolis is offered. Innovations in this paper:1. From the perspective of realistic background of rapid development and sustainable urban design, combining with the characteristics of urban renewal, analyze the relationship between urban renewal and economic, social and space environment. Meanwhile urban renewal orientation system which contains economic, social and space environment is proposed. Furthermore, combining with the urban space development strategy, renewal orientation of Tianjin central area is put forward.2. Based on the urban renewal orientation system, according to theory on organic evacuation, smart growth and circulation type, combining with the practice in western countries, a new method of urban renewal is put forward, namely comprehensive type, progressive type and incremental type.3. Based on the idea of building the harmonious society, a new organization and operation mode is proposed, namely: government leading-enterprise promoting-public participating, which means public-private partnership mode is created. This paper discusses the renewal operation of metropolis central area during the rapid development period.
