Abstract
Population is an important factor of food security. The land resources in Guizhou province are very scarce and the ability of grain production is weak. Guizhou province has long faced the problems of population growth and food security. Since 1990s, larger number of population began to outflow from Guizhou to other provinces, the gap between the resident population and the registered population was gradually expanding. Based on the background of population outflow, the paper studied the per capita grain and cultivated land pressure in Guizhou province, and found that, with the population outflow from Guizhou province, the level of its food security has been greatly improved. In the future, with the decreasing of the size of the floating population, the pressure of food security will gradually increase. In order to protect its own food security, Guizhou province should strengthen the protection of cultivated land and make full use of domestic grain market, at the same time, establish the concept of"food security".关键词
