| ［目的］我国的粮食安全问题一直备受关注，作为粮食安全重要保障的粮食主产区近年来却面临着粮食生产与经济发展协调性、可持续性下降的困扰。文章以湖北省46个粮食主产县为研究区，对其粮食生产与经济发展的耦合协调状况进行研究，以期为地方政府粮食安全政策制定提供参考。［方法］以研究区粮食产量、地区生产总值、行政区划图层为数据源，构建重心模型和空间耦合模型，对粮食主产县2006—2015年间粮食重心和经济重心迁移路径、粮食生产与经济发展耦合协调状况进行分析。［结果］（1）研究期间粮食主产县的粮食重心和经济重心整体上皆向西北方向转移，经济重心始终位于粮食重心东南部，经济重心的移动幅度大于粮食重心，但经济重心的移动方向更稳定。研究区北部的粮食生产地位高于南部，南部的经济地位则高于北部，粮食生产的稳定性相对低于经济发展。（2）两重心整体上虽均向西北方向转移，但具体移动方向存在较大差异，两者空间重叠性整体下降，变动一致性减弱，空间耦合性变差。（3）粮食生产与经济发展空间一致性地域分异特征明显，相较于2006年， 2015年粮食经济整体协调性进一步减弱，粮食生产与经济发展日趋分散。［结论］建立重心模型和空间耦合模型对粮食生产与经济发展耦合协调状况进行研究是有效可行的，为推动粮食生产与经济发展协调稳步发展决策提供一定的参考。 |

| Abstract: |
| The issue of grain security in China has been receiving much attention. In recent years, the main grain producing areas, which are important safeguard for grain security, have been plagued by the decline in the coordination and sustainability of grain production and economic development. This paper took 46 major grain producing counties in Hubei province as the research area, and studied the coupling and coordination status of grain production and economic development, in order to provide reference for local governments to formulate grain security policies. It used the grain yield, regional GDP, and administrative division map of the study area as the data source to construct the center of gravity model and the spatial coupling model. And it analyzed the migration path of grain center of gravity and economic center of gravity, and the coupling and coordination status of grain production and economic development in the main grain producing counties from 2006 to 2015. The results showed that (1) During the research period, the grain center of gravity and economic center of gravity in the major grain producing counties both moved to the northwest. The economic center of gravity was always located in the southeast of the grain center of gravity. The moving amplitude of the economic center of gravity was greater than that of the grain center of gravity, but the direction of economic gravitywas relatively stable. The status of grain production in the northern part of the study area was higher than that in the south, while the economic status in the south was higher than the north. The stability of grain production was relatively lower than that of economic development. (2) Although the two centers of gravity were both moving to the northwest, the specific moving directions were quite different. The spatial overlap between the two was generally reduced, while the consistency of the changes was weakened and the spatial coupling was reduced. (3) The spatial consistency of grain production and economic development was significantly differentiated. Compared with 2006, the overall coordination of grain and economy in 2015 was further weakened. And the grain production and economic development was increasingly scattered. It is effective and feasible to establish the gravity model and the spatial coupling model to study the coupling and coordination of grain production and economic development, and provide a reference for promoting coordinated and steady development of grain production and economic development. |
