新时期中心地理论创新与发展的基本视角和框架

he central place theory is one of the important thinking mode and method to solve practical problems and announce the law in urban geography. Facing time development, social transformation, technique progress and its results of great changes in the city and the region, central place theory calls for theoretical innovation and development. Firstly, to eliminate theoretical limitation to broaden the practical universality. The traditional central place theory is imposed severe assumption and is weak for its characteristic of dynamic and property of synthesis on natural-human factors. Secondly, to re-survey changes in central place system of its external conditions, internal factors, organization form and mechanism within new background dynamically. And it acquires angle of theoretical innovation which includes as follows. One is the angle of macro-background changes, such as spatial transference of population distribution, urban system recombination and global value chain rising. One is the angle of influential factors and mechanism, such as recombination of modem traffic conditions and central place system, information technology and organization networking of producing and living, technology revolution and transference of central place and its diffusion domain, system reform and principles of central place system organization. Another one is angle of changes in central place system organization form, such as global city networking, polymerization of urban, base central place organization. The last one is the angle of modem technology application, such as RS, GIS and modem statistical method. Finally, it is necessary to step into a stage of improving integrally from researching fragmentary in order to construct a basic framework of innovation and development of central place theory , which learnt from history lessons. (1) Innovation and development aim as direct practical application and form research paradigm of theory and method. (2) Key content of innovation and development are as follows: centrality measuring model, strict research conditions at alleviation, dynamic central place system, central place system distortion model, space nesting of diffusion domain. (3) Three issues are waiting to be solved: natural-human factors effect mechanism and model of the central place system, tracing the development of urban developing environment and central place structure morphology, changing static study into dynamic developing study.
