The paper expatiated the virtual water content concept of livestock products and the study meaning on developing virtual water trade of livestock products in China, then summarized the calculation methods on virtual water and virtual water trade of livestock products. Based on these, the paper analyzed and researched every province virtual water content of livestock products in details, then elicited various situation of every province virtual water content of livestock products in China by year. Moreover, it compared virtual water content of livestock products with local water resources. The study indicated the following results: (1) The virtual water content of livestock products is increasing rapidly in China recently, especially poultry eggs and pork. (2) The distribution of virtual water content of livestock products is not balanced, mainly lies in North China, East China and so on; (3) The increasing production of livestock in Beijing City, Tianjin City, Hebei, Nei Monggol, Liaononing, Jilin, Shandong, Henan and Ningxia province and autonom ous region will bring pressure to local water shortage.
本文阐述了畜产品虚拟水含量的概念以及在中国开展畜产品虚拟水贸易的研究意义，随后总结了畜产品虚拟水及虚拟水贸易的计算方法。在此基础上，详细分析研究了中国各省份畜产品的虚拟水含量，并逐年得出中国各省份畜产品虚拟水含量的各种情况。此外，还将畜产品虚拟水含量与当地水资源进行了比较。研究结果表明：（1）近年来中国畜产品虚拟水含量增长迅速，尤其是禽蛋和猪肉；（2）畜产品虚拟水含量分布不均衡，主要集中在华北、华东等地；（3）北京市、天津市、河北省、内蒙古自治区、辽宁省、吉林省、山东省、河南省和宁夏回族自治区畜产品产量的增加将给当地水资源短缺带来压力。
