河南省近期耕地资源与粮食生产能力变化研究

河南省的耕地资源在数量上不断下降，经历了一个先减少后稍有增加并趋于平缓的变化态势。研究认为，耕地资源的空间转移并没有引起相一致的粮食生产质心的转移。这说明该省耕地资源虽然最近几年保持了数量上的动态平衡，但是耕地资源的“隐形”减少，即耕地资源质量下降已经虞为影响粮食生产的重要因素。最后就保护耕地资源和保障粮食生产提出了对策和建议。

Changes of the Cropland and Grain Productive Capacity of Henan Province in Recent Years

The quantity changes of the cropland of Henan Province tended to an equilibrium situation after experienced a reduce and ascend process by analyzing the statistics data in recent 20 years. Whereas, the center of gravity change of the cropland does not bring about the consistent change of the grain production by comparing their spatial changes. It shows that the quality of the cropland had declined though the quantity of the cropland of Henan Province had preserved an equilibrium situation, this has become an important factor that influence the grain productive capacity. Furthermore, give the countermeasure and suggestion to protect the cropland and ensure the grain productive capacity by analyzing the influence to the grain productive capacity from the changes of the cropland through different point.
