工业产品虚拟水含量计算方法研究

虚拟水是指生产商品和提供服务过程中所需要的水资源．虚拟水战略是指贫水地区通过贸易手段从丰水地区进口水密集型产品，以保护本地区的水安全的战略形式．介绍了虚拟水的概念，归纳了农产品和畜牧产品中虚拟水含量的计算方法，并总结了有关产品虚拟水的研究成果和不足之处；提出了工业产品虚拟水的计算方法，以辽河油田为例，计算出石油制品中虚拟水含量．在此基础上．建议中国石油行业今后应有计划进口石油制品，缓解我国水资源紧缺的现状．

Study of virtual water calculation method of industrial products

Virtual water is the water used in the process of producing goods and providing services. Virtual water strategy is a strategy for protecting local water security in those water-scare regions by importing water-intensive goods from water-rich regions. The conception of virtual water was introduced, meanwhile, the virtual water calculation methods of agricultural and livestock products were summarized. In addition, the drawbacks of current calculation methods in regard of virtual water were pointed out. The virtual water calculation method of industrial products was put forward, and virtual water contained in oil products was calculated based on the case study area of Liaohe Oil Field. Based on the calculated results, appropriate import of oil products could improve water-scarce situation in China.
