Research On The Layout Of Urban Residential Space Under The Background Of Megacity Transformation

Along with the development of "double transition" and globalization,megacities which are the main node of regional network,are gathering all kinds of resources.With the rapid process of urbanization,megacities have been expanding urban areas rapidly and restructuring the urban space.Under the background of megacity transformation,the layout of urban residential space along with the interactive evolution with urabn space transformatioin,produced some new changes and characteristics.In 2006,more than 5 million people lived in metro area of Wuhan city,according to the latest standard of city scales,Wuhan has become a megacity.Wuhan have got a great development in recent 10 years.Urban built-up space has broken the limit of central city and expanded to the further new towns.Now Wuhan has initially formed the urban structure of “central city + new town groups”.Urban infrastructure construction is gradually improving and urban resident population scale is growing.Along with the urban development and transformation,Wuhan urban residential space also proves the trend of expansion and internal reconstruction,which brings a lot of problems,such as non-extensive space layout,dislocation of land and people,differentiation of residential space and so on.In recent years,Wuhan has become the national superposition with multiple strategies.It's necessary to analyze Wuhan residential space layout under the background of megacity transformation deeply.The reasonable layout will deepen the space development strategy,and achieve the urban development goals——“Grenn,Livable,Inclusive,Efficient,Dynamic”.This paper takes “Wuhan Metropolitan Development Area” as the research scople and takes “2006-2014” as the research period.At first,this paper analyzes the relationship between megacity transformation and urban residential space on urban system transformation,urban economic transformation,urban society transformation and urban construction transformation.Then the research analyzes the evolution of Wuhan residential space layout by the analysis of urban residential land data in recent 10 years,including evolution spatial pattern,evolution time series and the land development in evolution.On the basis,the research summarizes the characters of Wuhan residential space layout under the background of megacity transformation,including layout patterns of residential space,layout scale characters of residential space and layout type characters of residential space.At last,the paper summarizes the problems and targets based on the front research,provides optimization strategies about Wuhan residential space layout.
