摘　　要：计算比较了滇池流域包括农作物、养殖业、苗圃、科技示范园、休闲农家乐及蔬菜加工等在内的14种农业类型的单位净产值虚拟水。研究发现,单位产值所需虚拟水最多的是休闲农家乐,最少的是蔬菜加工业,其它农业类型单位产值虚拟水消耗量之间差异度较小。运用虚拟水理论核算出不同农业类型的单位产值虚拟水需求量,可以将有限的水资源投入到低耗水的农业产品,进口高水耗农业产品,优化区域农业产业布局,降低水资源的消耗,从而缓解区域水资源压力,实现水资源的优化配置。As a Macro Control Policy tool of a country or region,virtual water strategies the strategy of regional wa-ter resources and the combination of the water resources management and international trade.It will affect econo-my,society,and environment.Virtual water is a useful tool to help solve water crises,ecological degradation,and grain production issues.This study sleeted planting,breeding,leisure farm including14typical agriculture types in the Dianchi Lake basin and calculated the virtual water per unit of output.The virtual water per unit of output of leisure farm was the highest,vegetable processing was the least.This study has guided significance for selecting ag-riculture type,optimizing agricultural region in the Dianchi Lake basin,and improving water resource use efficien-cy,and mitigating regional water resources shortage.
