摘要
将城市增长定义为城市区域的生长或衰退。从这个角度出发,对城市区域进行了地理划分,并根据各因素对城市区域的影响,利用理论力学的原理,将城市增长动力归纳为向心力、离心力和摩擦力三种。分别介绍了三种动力的含义以及产生原因,最终得出城市增长是三者共同作用的结果。
In this paper,the definition of urban growth is the growth or decline of urban region. Starting from this angle,this article makes an division of urban region,at the same time,on the basis of the influencing factors,the force of urban growth be divided into three Kinds：centripetal force;centrifugal force and friction force by using theoretical mechanics prineiple.This article introduces the meanings and cause of these forces, and then the urban growth is the result of combined action of these three force is finally obtained.
