Changes of Agriculture Resources and the Influence of Grain Production Capacity of China in Recent Years

Qu Xuebing et al.(School of Land Science and Technology,China University of Geosciences,Beijing 100083,China)  
According to our country in recent years(from 2000 to 2008) changes in cultivated land resources,this paper analyzes changes in the overall grain production capacity and the influencing factors,including the correlation between the cultivation area,the grain sowing area,the grain yield level,and the changing ratio of the overall grain outputs between years.The results show that for food production and cultivated land area in China without decisive relations,China's recent food production capacity of the most important factor is the grain sowing area,and yield level,both the interannual variation with total grain output interannual variation are a strong correlation,which trends are basically the same.Finally,based on the conclusion of the paper,we explored the protection of cultivated land and grain security measures.
