摘要
Abstract
[Objective] This paper aimed at exploring the countermeasures for cultivated land protection and food security assurance and providing references for the formulation of policies related to cultivated land and grain production of the whole province. [ Method] Data of population, cultivated land, grain and others in Hunan Province during 1989 to 2008 were collected by county (district). The change of cultivated land and grain production of the whole province were analyzed using Geographical Information System (CIS). [ Result] The population was increasing continuously, the total area of cultivated land was reducing as a whole in spite of increasing in one or two year in one or two county, the total grain production and per capita grain yield was fluctuated within a certain range in recent 20 years of the whole province. The reducing of cultivated land was mainly due to the industrialization and urbanization development. The unbalanced quantity and quality of cultivated land, various natural disasters, readjustment of industry structure and inner readjustment in the agriculture, variety improvement and improvement of cultivated technology mainly affected of the grain production. [ Conclusion] The protection of the quantity and quality of cultivated land has to be strengthened to ensure food security. It is important to enhance the ability of resisting drought and flood disasters by improving the construction of agriculture establishment in order to insure the productivity of cultivated land, to increase farmers enthusiasm for growing grain with favourable food policy, to improve the per unit area yield of grain by variety improvement and to increase grain sown area by enlarging the double-cropping rice sown area.关键词
