利用基于纵向集成算法和假设抽取法的产业关联分析方法对2010 年浙江省各部门的用水关联性进行分析, 并据此获得经济部门间虚拟水转化运移情况。研究结果表明, 浙江省经济系统中各部门水资源直接消耗量与纵向 集成消耗量差异很大, 但是所有部门总的直接消耗量与总的纵向集成消耗量相等, 均为2201 08 亿m3 , 即经济系统 的不同部门之间发生了虚拟水转化运移。在经济系统内部, 农业为虚拟水净输出部门, 其净输出量为781 46 亿m3 , 而工业、建筑业和服务业则是虚拟水净输入部门, 净输入量为321 98 亿m3 、431 22 亿m3 和21 26 亿m3 。研究成果将 对区域产业结构调整和水资源管理政策制定提供参考。

Wat er use linkages among indust rial secto rs o f Zhejiang Pr ov ince in 2010 w ere ana lyzed using the indust rial linkage a2 nalysis metho d based o n the ver tically integ rated consumptio n and hypothetical ext ractio n method, and the tr ansformatio n of vir2 tual water among industr ial secto rs in the economic systems o f Zhejiang w ere obtained.
