大都市的扩展历程与大都市边缘区的城乡一体化问题分析

An Analysis on Metropolitan Expansion Process and Urban-rural Integration in Its Fringe Area

大都市经历了吸收为主到辐射为主的漫长发展历程,在吸收阶段,腹地与大都市之间会出现较大的发展差距。大都市在城市化进程中要发挥核心作用,就需要构建多种高效的辐射机制拉动腹地发展,比较有效的举措诸如"市管县"、"区划归并与分解"、"区划升级"、"扶持新城发展"等,通过行政介入,产生市场机制单独作用下不能产生的效果。城市发展进程中遵循"S曲线"规律、地租递减规律以及职能疏解规律。只有建立恰当的机制,才能发挥大都市的辐射作用,让大都市与腹地得到同步发展,带动更大腹地的城市化进程,大都市就会发挥出更大作用。在大都市的影响下,实现农民市民化、农业现代化、城乡文化一体化,小城镇在此过程中扮演着重要角色。

Metropolis has experienced the long term progress from the absorption to the radiation.In the absorption phase,the larger gap will appear between hinterland and the metropolis.Metropolis should play a key role in the urbanization process and it is necessary to build a variety of efficient mechanisms of radiation to stimulate hinterland development.More effective measures,such as the＂city administrating county＂,＂division merge and decomposition＂,＂division upgrade＂,＂support of the development of new city＂etc.can be applied.Through engaging in administrative measures,it can produce the effect which is not based on the market mechanism alone.Urban development must obey many rules such：＂S＂curve law,land rent diminishing law and the law of functions relief.Only by establishing aproper mechanism,can the metropolis play a role of radiation,resulting in the synchronous development of metropolis and hinterland.The city will play agreater role in driving more hinterland to step into the process of urbanization.Under the influence of the metropolis,citizenization of farmers,agricultural modernization and integration of urban and rural culture can be realized in which small towns will play an important part.
