对城市吸引区范围界定的理论分析

A Theoretic Analysis of Ascertaining the Cities' Gravitation-Regions

文章从区域与城市发展的特点和规律入手,引入了通达性和人为干扰等因素作为解释变量对“雷利公式”进行了改良。以此为基础,文章运用断裂点理论和改良后的雷利公式对受到不同影响下城市吸引区范围的界定、大城市对邻近小城市的“屏蔽”效应等一系列问题进行了理论上的分析,并对处于不同区域环境下的城市的发展策略选择提出了相关的思路建议。

Based on the characteristics and rules of the regions and the cities＇ development, this article introduces the factors of negotiability and jamming to improve the traditional Reilly＇ s Formula. Then, with the help of the Breakpoint Theory and the improved Reilly＇s Formula, this article studies the cities＇ gravitation-regions under different conditions, the big cities＇ shield effect and so on. And finally, some suggestions are put forward.
