EVOLUTION OF CHINA'S REGIONAL FOOD SECURITY:1949-2008
利用人均粮食占用指标，评估了1949至2008年中国区域粮食安全的变化，发现整体安全水平虽低但趋好，主产区明显改善，非主产区稳定，东、西部先好后差，中部整体向好。
Assessing China's regional food security from 1949 to 2008 by using food occupation per capita,this paper shows that ① China's food security is turning for the better,though overall security level is still relatively low;② food security in major grain production regions is obviously turning for the better,however food security in non-major grain production regions stays stable;③ food security in eastern and western China turned for the better,then for the worse,whereas in central China turned for the better as a whole;④ food security at provincial-level turned for the better.
