| 摘 要： | 利用海南岛人口、经济数据,基于重心模型和GIS平台研究了海南岛人口重心与经济重心的移动轨迹及两者的耦合度变化情况。研究结果表明2011-2019年海南岛人口重心、经济重心都偏离本省地理几何中心,位于其东北部,经济重心偏离程度更大;两重心耦合度较低,其空间距离逐渐缩小,但变动方向不一致,说明人口经济发展不平衡.

| Abstract: | Based on the gravity center model and GIS platform,we used population and economic data of Hainan Island to study the movement trajectory and the coupling degree of population and economic gravity centers.The results show that both the population and economic gravity centers of Hainan Island are in the northeast of Hainan Island and have deviated from the geographical and geometric center of the island from 2011 to 2019.The degree of economic center deviation is greater than that of population center.The coupling degree of two gravity centers is weak,which is reflected on their inconsistent change direction,even though their spatial distance reduced.This reflects unbalanced development between population and economy in Hainan Island. |
