摘　　要：综合运用样带、空间分析、地理探测器等方法分析1997—2010年江西省县域单元人均粮食占有量的时空格局演变及其形成机理。江西省县域人均粮食占有量空间集聚特征明显,呈较明显的圈层分布;全省大部分县域为余粮区,过半数的县域人均粮食有所提高,主要集中于赣中平原和赣北鄱阳湖周边地区。江西省县域人均粮食的空间格局主要受1997年人均粮食占有量与人均耕地面积的影响,仍对农业生产地理基础表现出较大的依赖,粮食政策、市场价格等对区域粮食生产亦有一定影响。样带趋势分析显示14年来全省县域人均粮食的东西向变化较南北向大;样带地理探测分析则有助于深入认识不同农业生产自然条件、不同经济发展水平等县域人均粮食驱动机制的差异。The article not only analyzed the evolving patterns both in time and in space of the food per capita in Jiangxi, but also their formation mechanisms by transects, spatial analysis, geographic detector and other methods on the base of county region. The food per capita in counties of Jiangxi has a significant characteristic of spatial cluster, and shows obvious character of circular distribution in major years. Most counties of the whole province are grain-surplus regions. And the food per capita has improved in more than half of the counties of the province, largely concentrated in the center and north of Jiangxi around Poyang Lake. The spatial pattern of food per capita in Jiangxi is mainly influenced by the food and area of cultivated land per capita in 1997. It shows great attachment to physical geography condition of agri- cultural production. Furthermore, food policy and market price also have certain impact on regional food production. The transect analysis can deeply explore the temporal-spatial variation law and the driving mechanism of the whole province＇ s food per capita. In the transect trend analysis, The east-west trending variation of the whole province＇ s food per capita is bigger than that of the north-south trending for fourteen years, and the geographic detecting analysis of transects is helpful to further understand the different driving mechanism of food per capita in the counties with different physical condition of agricultural production or counties with different economic level in the region.
