摘　　要：运用重心概念及相关公式,采用各县区的人口、GDP及粮食作物产量数据计算改革开放以来宁夏人口重心、经济重心和粮食重心,并对三者的动态演化、驱动因子及耦合关系进行研究。结果显示:①宁夏经济重心明显偏北,移动幅度较小;②人口重心由几何重心南侧快速移动到北侧,且继续北移,移动幅度较大;③粮食重心主要位于几何重心北侧,重心的跳动幅度最大,且最不稳定,规律性不明显;④宁夏经济重心与粮食重心的空间耦合性不高,人口重心与粮食重心具有空间耦合性,经济重心与人口重心具有显著的空间耦合性。Using the concept of gravity center and correlation formula, applying various counties in population, GDP and crops yield data to calculate the gravity center of population, economic and grain, study their dynamic evolution, driving factor and coupling relationship. Results show： （1）Economic gravity center in north is obvious and its movements are small;（2）Population gravity center quickly moved from south geometric center to the north, this trend will continue to persist and the movements are larger;（3）Grain gravity center is mainly located in the north side of the gravity centre, the movements are the largest and the most unstable, and no obvious regularity; （4） The space coupling of gravity center of economic and grain is not high, gravity center of population and grain have the space coupling, the space coupling is most obvious in economic and population.
