摘要: 采用生产树法，初步测算了不同类型森林的单位虚拟水量，进而计算了主要木质林产品的单位虚拟水含量，测算了中国主要木质林产品虚拟水贸易。研究结果表明，林产品属于水密集型产品，林产品贸易中蕴含了巨量的虚拟水贸易。通过调整林产品贸易政策、改善林产品出口结构、提高林产品虚拟水贸易净进口，可以提高水资源的利用效率，缓解水资源严重短缺的问题。

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.
