Research Of Construction Strategy Of China’s Large Cities And Their New Cities In Organic Evacuation Process

With China’s economic and social development, the process of city constant speed,big city development momentum is strong. However, in the process of city in China, therapid development of part of the city’s steamed slowly out of the rational expansion of thetrack, one-sided "city of" led to excessive development of city, big city "pie" gave birth tothe serious urban diseases. Therefore, for the development of the present stage of ourcountry big city, need to evacuate the city function and space, realize the rationalexpansion.In this paper, through the introduction of biological community "symbiosis concept",namely from the perspective of organic evacuation theory of Saarinen and in the specificconnotation of city growth based on the definition, constructs a theory support large cityoutward evacuation and expansion. At the same time as the receiving container large citymetro evacuation function, make a concrete analysis of metro construction strategy.First of all, this article on "organic evacuation theory" and "garden city","ecologicalcity theory" and "organic concentration theory" difference analysis and research, summedup the "organic evacuation theory" is located in a big city in China’s advantage. The strictdefinition of "big city" and "town", determine the object of the study.Secondly, through the longitudinal comparison and the comparative analysis method,the development course of stage characteristics of foreign new interpretation of cognitiveunderstanding, analysis of organic evacuation theory to detailed, and summarizes theexperiences and lessons of new town construction success or failure in foreign countries.And combined with the status quo of the big city in our country, summarizes the purposeand significance of the new town in china. Based on our country’s large population andgrowing fast, low per capita income of objective conditions, analysis of the problem facingthe city in our country outward evacuation routes and Metro construction.Then the big city in the regional development space, study it self evacuation andoutward evacuation two evacuation style. At the same time in the big city of organicevacuation in Metro, the growth is closely related with it, central city function, population,industry of outward evacuation, and to undertake the development of metro, the twomutually succession symbiosis. The close relationship between Metro and city based inmetro construction, put forward specific measures for implementation of its functions, the optimal quantity, the optimal scale and construction principle and so on, to guide the actualconstruction.Finally, based on China’s capital of Beijing city and the surrounding city as anexample, validation. Summarized the main stages of the development of Beijing Metro andits reach, and puts forward some suggestions on the construction of new Beijing city after.The purpose of this paper is the ultimate goal of promoting regional development inthe city at the same time, to provide intellectual support to create good living space of city.
