武汉城市圈空间结构演化及影响研究

武汉城市圈是我国资源节约型、环境友好型社会建设的重点示范区，是中部崛起战略实施的重要支点。但就现阶段的发展情况来看，武汉城市圈在空间结构方面存在一些问题，制约了城市圈的总体发展。采用两方面的方法对武汉城市圈的空间结构展开研究。一方面，利用数理分析确定武汉城市圈的城市职能等级体系；另一方面，利用针对历史建成区的图面分析和方格网分析确定城市圈空间结构的演化历程。结合两方面的研究结论，将武汉城市圈的空间结构确定为单核模式，即由一个较大的核心城市和若干个组团城市结合而成的空间结构模式。单核模式有利于培育强有力的核心城市，突出核心城市的辐射带动作用，但不利于组团城市的扩张和城市圈的总体长远发展。在此基础上，提出了优化武汉城市圈空间结构的初步设想，包括联合一些组团城市建设发展中心，突出一些组团城市特色功能等

STUDY ON EVOLUTION AND EFFECTS OF THE SPATIAL STRUCTURE OF THE WUHAN URBAN AGGLOMERATION

The Wuhan urban agglomeration is the important region of construction of resource saving and environment friendly oriented society of China,and the significant pivot of the strategic of central China rise abruptly.But in nowadays,there are still some problems in the spatial structure of the Wuhan urban agglomeration,which would do some harmful effects in the development process of the whole urban agglomeration.To explore the spatial structure of the Wuhan urban agglomeration,a series of methods were applied in this study:a mathematical analysis to ascertain the framework of cities in this urban agglomeration,a research on the completed areas expansion and population density based on the grid analysis to ascertain the historic evolution process of this urban agglomeration.It has been identified that a single nucleus model could be the best model to suit the spatial structure.The single nucleus model,which is composed by a large nucleus city and several cluster cities,can be utilized to grow up powerful nucleus,speed up the expansion of nuclear city,but it isn’t beneficial to the growth of the cluster cities and the long-term development of whole urban agglomeration.On that base,some preliminary ideas which can optimize the spatial structure of the Wuhan urban agglomeration were introduced,including combining cluster cities into developing centers,enhancing the main functions of some cities,etc.
