Abstract: This paper uses the production tree method to estimate unit virtual water content of different tree species, and calculate unit virtual water content and virtual water trade of main woody forest products in China. Results show that woody forest products are waterintensive. Woody forest product trade contains a huge amount of virtual water trade. It can improve the efficiency of water resource and relieve the pressure of water shortage by adjusting trade policies, improving export structure, and increasing net import of virtual water trade of forest products.
