| 摘 要： | 虚拟水贸易是实现缺水地区可持续发展的重要战略选择，也是实现区域水资源优化配置，提高用水效率的有效工具。介绍了虚拟水含量的计算方法，并以河南、江西、湖南、湖北为例计算了四省的虚拟水贸易量，结果表明，河南省粮食产品的虚拟水含量较其他三省少，四省都是虚拟水净输出地区，虚拟水净输出量为151．37～476．47亿m^3。

| Abstract: | Virtual water trade is an important strategy for sustainable development in water shortage regions, and also an effective tool to optimal allocate regional water resources and to promote water use efficiency. The calculation method of virtual water volume is introduced, and case studies of virtual water trades of the four provinces in middle China, Henan Province, Jiangxi Province, Hunan Province, and Hubei Province, are conducted. The results show that the virtual water volume of food production of Henan Province is less than those of the other three provinces, and all the four provinces are net exporting area of virtual water, the total net exporting virtual water is 15.137 billion - 47.647 billion m3. |
