郊区化界定标准辨析

An analysis of the definition criterion of suburbahnization

以美国为例,论证人口绝对和相对指标无法有效地界定郊区化.指出郊区化本质在于城市功能从中心市向郊区的扩散,城市功能包括居住、产业等诸多方面,人口绝对和相对指标只反映了人口的居住情况,只能在一定程度上反映城市功能.而且用人口数量变化作为界定郊区化的标准,把人抽象成一个个简单的数字单位,忽略了不同人之间所体现的城市功能是有所差别的.指出只有建立一套科学的城市地域统计单元和城市功能评价方法,才能有效地界定城市化是否处于离心郊区化的发展阶段.

America is taken as an example and,it is proved that target population can not define suburbanization.It is pointed out that suburbanization is dispersion of urban function from central city to suburb.Urban function includes residence,industry and so on.Target population reflects and only partially reflects urban function.Furthermore,this method takes people as a single number and ignores different urban functions.Through the analysis,it is pointed out that only by founding a scientific statistical standards of urban places and urban method which could evaluate the city＇s function can it be defined why urbanization lies in the developing stage of suburbanization.
