人口净流出背景下贵州省粮食安全的研究

Food Security of Guizhou Province against the Background of Net Outflow of Population

通过对贵州全省及县域空间上的净流出人口现状的分析,探究人口流出对全省及县域空间上的粮食安全的影响。结果表明,贵州省人口净流出提高了粮食安全水平;从空间上看,由于人口净流出,使贵州省粮食富余县市粮食富余总量增加,更好填补了缺粮县市的粮食缺口。通过粮食的空间调配使全省实现区域上的粮食供求平衡。

The current situation of spatial net outflow of population in Guizhou province and 87 counties was analyzed to explore the effect of net outflow of population on food security in spatial.Results showed that the food security level and total amount of surplus food in counties with more food than needed were enhanced,and surplus food was supplied to counties in short supply of food,and regional balance between supply and demand of food in Guizhou province was realized by spatial deploying.
