| 摘 要： | 通过对河南省农业水资源与耕地资源的利用态势进行模拟分析，构建区域水土资源匹配测算模型，将匹配结果与产能分布情况做相关性分析，探讨河南省农业水土资源匹配格局对粮食产能的影响．结果表明，河南省耕地资源优势明显，水资源匮乏，水土资源匹配较差；水土资源匹配程度与耕地产能的空间分布呈现出明显的错位现象，这是由于产能高产区垦殖率高，灌溉条件好，过度利用水资源引起的．

| Abstract: | The modeling and comparative analysis was applied to discussion on productivity of spatial matching patterns by simulating agricultural land and water resource utilization state,building regional water and soil resources matching and calculation model,analyzing the results and productivity distribution correlation in Henan province.It is enough to prove that Henan has obvious advantages of farmland resources,but is short of water resources and is poor of the match of land and water resources;Matching degree of land and water resources and the spatial distribution of land productivity shows significant dislocation,which is caused by high cultivation rate in high yield area,good irrigation and excessive use of water resources in Henan province. |
