摘要
粮食安全关系国计民生。以江汉平原19个县域单元为研究对象,以2000年~2015年粮食产量数据为基础,采用GIS空间分析和数理统计分析方法,对江汉平原粮食生产的时空格局及演变规律进行研究,进而探讨其影响因素。结论如下:(1)江汉平原粮食产量持续增长,空间集聚日益加强,粮食高产区集中在平原东部地区,低产区分布较散,日趋边缘化;(2)江汉平原粮食生产重心呈现出东进南移趋势,空间格局趋于稳定;(3)推进形成江汉平原粮食生产空间格局的影响因素主要包括耕地资源的时空变化、农业机械化水平的提升、农业从业人口的流失以及城镇化、工业化的冲击等。
Food security concerns national economy and people＇s livelihood.Taking 19 units of county units in Jianghan Plain as the research object,based on the grain yield data of Jianghan Plain from 2000 to 2015, this paper studies the spatial and temporal changes of grain production in Jianghan Plain through GIS spatial analysis methods and mathematical statistics methods, and then discusses its influencing factors. The conclusions are as follows：（1）the grain production in jianghan plain continues to increase, the spatial agglomeration is increasingly intensified, and the high grain producing areas are concentrated in the eastern part of the plain, and the distribution of low-producing areas is scattered and increasingly marginalized;（2）the center of gravity of grain production in jianghan plain shows the trend of moving eastward and southward, and the spatial pattern tends to be stable;（3）the factors influencing the spatial pattern of food production in the Jianghan Plain include the temporal and spatial changes of cultivated land resources,the improvement of the level of agricultural mechanization, the loss of the agricultural workforce, and the impact of urbanization and industrialization.
