城市蔓延的界定及其测度问题探讨——以长江三角洲为例

Abstract

随着城市化进程的加速,城市蔓延已经成为当前中国不容回避的问题。要正确认识城市蔓延问题及其严重程度,就必须先在基础层面上解决城市蔓延的界定及测度问题。本文将城市蔓延理解为过度的城市空间增长,基于这一基本认识构建了测度城市蔓延的蔓延指数,并以长江三角洲区域为案例,对有关城市的空间蔓延进行了实证测度研究。

With the acceleration of urbanization,urban sprawl has become China's unavoidable problem.To understand the problem of urban sprawl and its severity correctly,we must clarify the definition and measurement of urban sprawl at the basic level.This paper regards urban sprawl as the excessive urban spatial growth,and sets up an urban sprawl index based on this understanding.With Yangtze River Delta Region as an example,we conduct an empirical study on the urban sprawl.
