摘要
从我国粮食生产总量,3种主要粮食作物(小麦、玉米和水稻)产量的时空变化,以及我国粮食生产重心的空间迁移等角度,分析阐述了我国粮食生产的时空格局变化规律,探讨其原因所在,并提出相应的策略和建议。
A comprehensive analysis on the change of the total grain production and the temporal and spatial change of three main crops production（including wheat,maize and rice）,as well as the transfer trace of the center gravity of grain production in China were analyzed to reveal the overall developing trend of the grain production,explore the reasons and finally propose the corresponding suggestions and strategies to cope with the situation.
