摘要
首先引入ET和虚拟水及水分生产率的概念,详细介绍目前ET和虚拟水及水分生产率的计算方法,并对ET与农产品虚拟水的相互联系进行重点探讨,同时就目前国际上较为先进的ET技术和虚拟水战略理论的概要进行解释,提出了农业结构战略性的调整和区域水资源管理的有效措施和建议。
In this paper, at first explaining concept of ET and virtual water, then analyzing the relation between ET and virtual water, and illuminating the significance of ET technique applying on really saving water .In conclusion, some suggestions have been put forward on how to adjust the structure of agricultural products so as to alleviate the press of water shortage in water-shorting areas and bring innovation to water resources management mechanism.
