摘　　要：深入了解太原市经济与人口分布时空规律,可以促进区域可持续发展。为此,选取了太原市2011-2020年间的经济与人口数据,采用重心模型,通过计算相应的空间重叠度与变动一致性指标,在ArcGIS软件中对太原市十年内的经济重心与人口重心动态变化轨迹与空间变化耦合度进行可视化分析。结果表明,2011-2020年太原市经济重心与人口重心都位于太原市地理几何中心的东南部;两重心的空间重叠度呈上升趋势,变动一致性较高,均向东南部方向偏离,但空间耦合度整体较弱,表明太原市东南部区域人口与经济发展较为协调,但与其他区县差距明显增大,且各区县之间发展协调性较弱。In order to understand the spatiotemporal regulation between economic and population distribution in Taiyuan city.We selected the economic and population data from 2011 to 2020 in Taiyuan,combined with the gravity center model,spatial overlap and change consistency index,and visually analyzed the dynamic change trajectory and spatial change coupling between economic and population gravity center in Taiyuan city with ArcGIS.The results show that the economic gravity center and the population gravity center are located in the southeast of the geographical geometric center of Taiyuan city from 2011 to 2020,indicating that population and economic development in the southeast of Taiyuan are relatively coordinated,but the gap with other counties is gradually increasing,and the internal coordination among counties is worse.

关 键 词：经济重心 人口重心 太原市 空间变化耦合度 变动一致性
