本文运用区位熵指数和相对增长速度指标对我国各省区稻谷、小麦、玉米和大豆生产的比较优势进行了测算。结果表明，我国主要粮食品种生产的区域比较优势存在较大差异，并且优势产区正在逐步北移。在我国主要粮食品种生产的空间格局发生重大变化的情况下，加快培育玉米和大豆优势产区将成为未来我国粮食安全的重点；水资源将成为我国粮食生产的硬约束；加快粮食流通体系建设是确保我国粮食供需平衡的关键。

This paper uses the location quotient index and relative growth rate to measure the comparative ad- vantage in the production of rice, wheat, corn and soybeans in different provinces of China. The result shows that there exists great difference in the production of major grain varieties in different areas of China and that the northern areas are accumulating their competence. Because great changes have taken place in the space structure of the production of major grain varieties and water resources will constitute a rigid restraint in the production of grain, it will become the priorities in guaranteeing the Chinese future food safety to promote the nurturing of areas with advantage in the production of corn and soybeans, and it Hill become the key for guaranteeing the balance between the demand and supply of grain to enhance the development of grain circulation system.
