Study On The Level Of Urbanization Of Three Urban Agglomeration In The Yangtze River Economic Belt

Urbanization is an important part of building a well-off society in an all-round way in China. It is the only way to realize modernization. It is the largest domestic demand potential and development momentum in China. Traditional extensive expansion of Urbanization Model in promoting the rapid growth of urban population, but also led to the expansion of urban space disorder, a large number of resources consumption, urban environmental degradation and other significant urban problems. Therefore, to promote people-oriented, comprehensive and coordinated sustainable development of new urbanization model has become an inevitable trend of urban development. The Yangtze River economic belt is China of opening to the outside world, between the East and the west, the coordinated development of important economic support, the Yangtze River Delta city group, the middle reaches of the Yangtze River city group and Chengdu Chongqing urban group is an important component of the Yangtze River economic belt, it is of great significance to promote the urbanization of the Yangtze River economic belt to optimize the layout and shape of the urbanization along the Yangtze River, and enhance the ability of urban sustainable development.The research content of this article mainly includes the following 4 aspects:(1)Through the review of domestic and foreign urbanization research achievements and China’s urbanization trends, to understand China’s recent new urbanization conference and the spirit of the document based on, the abstract model of urbanization concept more specific.(2) From the new town of the concrete connotation of hands, using the analytic hierarchy process, construction of culvert target layer, six criteria, 30 index of new urbanization level measure model, urban agglomeration, urban core, a delegation of the city three level comparison cities in the Yangtze River economic belt group new urbanization“1 + 6” spatial characteristics.(3) On the basis of the urban agglomeration of new town development characteristics and key issues, propose the Chengdu Chongqing urban agglomeration, urban agglomeration in the middle reaches of the Yangtze River, the Yangtze River Delta city group, the construction of new towns of policy recommendations.The research conclusions mainly include the following 6 aspects:(1) the connotation of China’s new urbanization can be specific to "people-oriented, intensive and highly efficient, perfect function, urban and rural, four synchronous, green, low carbon" six philosophy.(2) Since the founding of new China, Chinese urbanization has experienced starting, wandering, rising, soar four stages. At present in the new urbanization stage.(3) The results of the model show, the Yangtze River economic belt new urbanization level in stage II, the Yangtze River Delta in stage III, and Chengdu Chongqing urban agglomeration and the middle reaches of the Yangtze River city group are in phase II.(4) ChengduChongqing urban agglomeration urbanization prominent characteristics embodied in the low level of urbanization, urban and rural dual structure is prominent, co-ordination is very difficult, poverty alleviation heavy task; backward economic development, a higher proportion of industrial, resources and energy consumption; infrastructure construction is lagging behind, lack of public service facilities; high degree of the first urban core. Other groups between cities weak gravitational.(5) Urban agglomeration in the middle reaches of the Yangtze River urbanization prominent characteristics embodied in infrastructure construction serious lag, tour city loosely connected; regional cooperation mechanism is not perfect, administrative segmentation phenomenon is more prominent; large differences in the level of urbanization space, increase the pressure to protect the ecological environment; information construction and development of agricultural modernization needs to be strengthened.(6) Cities in the Yangtze River Delta urban agglomerations of prominent features embodied in the urbanization rate is high, but the level of urbanization is uneven distribution of; high level of economic development, fuzzy positioning of urban and industrial division of labor; the excessive concentration of population, environmental capacity.To promote the cities in the Yangtze River economic belt group new urbanization development, it is necessary to strengthen the urban agglomeration transportation infrastructure construction, condensation of the Yangtze River economic belt development efforts; optimization of the Yangtze River Economic Belt of urban agglomeration of urban spatial structure layout, city to promote coordinated development interactive; optimization of urban industry development environment, promote the transformation and upgrading of the industrial city group; strengthen the Yangtze River Economic Belt of urban ecological construction, to achieve sustainable urban development; speed up the reform of the system of urban and rural, improve urban public service facilities.
