虚拟水理论与方法的研究进展

虚拟水是当前研究的热点领域，是实体水资源概念在经济社会领域中的拓展。本文在对虚拟水相关概念和意义介绍的基础上，对国内外有关虚拟水问题的研究进展分虚拟水理论研究、虚拟水贸易与粮食安全、虚拟水战略、水生态足迹、虚拟水量化等5个方面进行了归纳和总结，最后探讨了未来虚拟水的研究方向，认为水资源概念的扩展、虚拟水的量化、以虚拟水概念理论制定相关政策、水生态足迹和虚拟水贸易平衡等5个方面是未来可以深入讨论的重点。

Progress of study on theory and method of virtual water

Virtual water is an expansion of the real water resources conception in the society. It is one of the hot topics at present. After an introduction of the virtual water and its related concepts, this paper summarizes the progress of studies on the theory and method of virtual water in China and abroad. The status can be generalized as in 5 aspects, i. e. , virtual water theory, virtual water trade and food secuity, virtual water strategy, eco- water footprint and quantification of virtual water. The authors foresee some future research topics. It is thought that the expansion of real water resource conception, quantification of virtual water, policy-making based on virtual water theory, eco- water footprint and virtual water trade balance would be the 5 key points of research in future.
