基于引力模型的郴州市城镇空间结构动态研究

Research on the dynamics of urban spatial structure in Chenzhou city based on the gravity model

城镇空间结构的布局合理性对城镇化进程以及区域经济发展有着举足轻重的影响。以郴州市城镇空间结构布局的发展历程作为突破点,以空间引力模型作为主要研究方法,选取郴州市2009年、2014年、2019年三个五年间隔的时间点相关数据作为测算依据,分析研究郴州中心城区和9个地级市县之间的经济联系强度以及地级市县对中心城区的经济隶属度变化,以此定量分析城镇空间的基本经济情况,探讨郴州市城镇空间结构演化的相关特征。

The rationality of urban spatial structure layout plays a decisive role in the process of urbanization and regional economic development.This paper takes the development history of the urban spatial structure layout of Chenzhou city as a breakthrough point,uses the spatial gravity model as the main research method,and selects the relevant data at three five-year intervals in Chenzhou city in 2009,2014,and 2019 as the basis for calculation and analysis.Then this paper researches the intensity of economic ties between the central city of Chenzhou city and 9 prefecture-level cities and counties,and the changes in the degree of economic subordination of prefecture-level cities and counties to the central city,to quantitatively analyze the basic economic situation of urban space and to explore the related evolutionary features of urban spatial structure in Chenzhou city.
