摘　　要：粮食安全和水安全对人类生存与发展具有极其重要的意义。以水资源的可持续利用来保障粮食安全已经成为国内外学者关注的焦点,同时也是实现水资源合理配置的迫切要求。本文分别从水量和水质两个方面对水资源与粮食生产的关系进行了回顾和总结,分析了当前研究中存在的问题,认为单纯从水量或水质的角度研究水资源对粮食生产的影响不能满足实际的要求。因此,应在研究水量和水质分别对粮食生产影响的基础上进行耦合,构建综合考虑水质和水量影响的水资源-粮食产量模型。Food security and water resources play an important role in the subsistence and development of humans.The sustainable use of water resources to ensure food security has become the focus of scholars.It also requires the rational allocation of water resource.This paper reviews the relationships between water resources and food production and summarizes them from two aspects of water quantity and quality.It indicates that studying the relationship between food production and water quantity or quality respectively does not meet the requirements of practical applications.Therefore,the Water-Yield model,considering both water quantity and water quality,should be established.

关 键 词：水量 水质 粮食生产
