| Abstract: |
| This paper makes a dynamic analysis of the grain production, and carries an analysis and an evaluation of the food security from 1949～2007 in Inner Mongolia, through collecting, sorting and making statistics to the historical documents and data. The results show that: the total population shows basically a linear increase trend; the cultivated area makes a steady increase; the grain planting area shows a first increase and then decrease trend, but it still shows an increase trend; the per unit area grain yield increases significantly and the increase range is more than the total grain yield; the total grain yield shows generally a steady increase situation; the per capita grain yield shows a rising trend in fluctuation. The food security is generally in the absolutely safety state, but there are some differences in space. The paper finally advances some countermeasures and suggestions to develop grain production and to ensure food security. |
