摘　　要：在区域发展过程中,研究其经济与人口的时空变化规律,可以对区域发展的均衡性进行评价。选取赣州市2012—2020年人口与经济数据,通过计算重心模型和空间耦合度,分析了赣州市经济重心与人口重心的空间变化特征和耦合关系。结果表明:赣州市2012—2020年的经济重心和人口重心与几何中心位置不一致,分别位于几何中心西部和北部;经济重心和人口重心的空间重叠度呈先下降后缓慢上升的变化趋势,处于相对稳定状态;经济重心和人口重心的变动方向一致性指数低,呈先上升后下降的变化趋势,变动距离一致性总体略高且变化度相对平稳。说明赣州市目前人口与经济发展协调性较差,但已呈现出积极向优的调整趋势。In the process of regional development,studying the temporal and spatial changes of its economy and population can evaluate the balance of regional development.The population and economic data of Ganzhou City from 2012 to 2020 were selected,and the spatial variation characteristics and coupling relationship between the economic center of gravity and the population center of Ganzhou were analyzed by calculating the center of gravity model and spatial coupling degree.The results showed that the economic center of gravity and population center of Ganzhou City from 2012 to 2020 were inconsistent with the geometric center,which were located in the west and north of the geometric center respectively;the spatial overlap between the economic center and the population center showed a trend of first decreasing and then slowly increasing;The consistency index of the change direction of the economic center of gravity and the population center of gravity was low,showing a trend of increasing first and then decreasing.The consistency of the change distance was slightly higher and the degree of change was relatively stable.This indicates that the population and economic development of Ganzhou city is in poor coordination,but it has shown a positive trend of adjustment.
