Abstract:

Researches on virtual water in trade make people know that water crisis in the region could be alleviated through the global economy and trade.The import and export of virtual water is a source of water resources.Through trade and a variety of external resources,the shortage of water resources and food safety could be finally resolved,which is the base of community to achieve community management of water resources,ecological environmental security and socioeconomic sustainable development.The object of study is Zhejiang Province.Firstly,we used various types of crop virtual water standards,and calculated the virtual water content of food trade in Zhejiang Province during 1997~2006.Then,we compared the annual water consumption in Zhejiang and the structure of water consumption.From the calculation,we found that the net import of virtual water generated from grain trade in Zhejiang was about 7.41% of total water consumption and about 17.17% of agricultural irrigation water.The results showed that the virtual water in Zhejiang grain trade was an important water resources supplement over the past decade.
