摘　　要：基于31个省市区粮食和3种主要粮食作物的产量数据,运用描述性统计分析、GIS、空间自相关分析等方法系统刻画了1978—2010年中国粮食生产空间布局的时空特征。结果表明:粮食产区逐渐向东北和中部集中;南方稻谷优势区域继续稳固的同时东北稻谷重要性逐渐凸显;小麦产区逐渐向北方和中部集中;玉米产区逐渐向东北、华北和华中集中;粮食、稻谷和玉米的重心向东北移动251.20km、286.45km和106.14km,但小麦重心移动方向不明显且距离也较短;粮食及稻谷、小麦、玉米生产均存在显著空间相关性,其中粮食、小麦、玉米生产空间集聚效应增强,稻谷生产空间集聚效应减弱。The analysis of this paper is based on the output data of 31 provinces＇ grain and three main crops in China; the author uses Statistical analysis, GIS method, and spatial autocorrelation analysis to study the characteristics of grain production＇ s spatial distribution in China from 1978 to 2010. The result of this analysis shows that the major producing areas of grain are moving to the northeast and central regions of China; Southern China maintains the position of the main producing areas of rice and the scale of rice production is expanding in northeast China; the major producing areas of wheat are moving to the northern and central regions of China; the major producing areas of corn are moving to the northeast and central regions of China; The center of gravity of grain, rice and corn have moved northeastward about 251.20kin, 286.45km and 106.14kin, but the distance of the movement of the center of gravity of wheat is not significant and short; China＇ s grain and main crops have significant spatial correlations, and the degrees of spatial concentration of China＇ s grain, wheat and corn are increasing, but the degree of spatial concentration of China＇ s rice is decreasing.
