摘  要：
以我国大陆30个省、直辖市、自治区为研究单元,以人均粮食占有量为测度指标,从各区域人均粮食占有量的标准差、变差系数等角度定量测度了1990—2015年省际人均粮食差异的总体水平及其变化特征,从各省份温饱水平的比率变化、人口-粮食比重等方面探讨了区域人均粮食占有量差异的空间结构特征,并因地制宜提出调控人粮关系的战略性对策。

摘  要：
Explored the methods for studying regional,per capita grain difference in the aspects of research unit were decided,measurement index were chosen,and measurement means were selected. Taking 30 provinces,autonomous regions,and municipalities in mainland China as regional study unit,and per capita grain as total index,it quantitatively measured the overall level and the characteristics of dynamic variation of the recent inter-provincial per capita grain difference from the angles of standard deviation,and standard deviation coefficient of every region's per capita grain. It also quantitatively measured the characteristics of spatial structure of this differential variation from the angles of the ratio of every region to the subsistence level,and the proportion of population-grain. Finally we put forward the strategy countermeasure on the regulation and control the relations between the population to grain and cultivated land,and to ensure grain safety in this paper.
