摘　　要：虚拟水是结合产品和服务中提出的水资源消耗量,文中采用虚拟水足迹的方式计算了西藏的城镇和农村水足迹,并对二者虚拟水足迹进行了分析:其共同点是在2006年前均呈现上涨趋势,而在2006年后均呈现下降趋势;其不同之处是农村虚拟水足迹以农作物虚拟水消耗为主,而城镇虚拟水足迹以畜产品虚拟水消耗为主。同时通过水足迹盈亏分析发现了西藏城乡居民虚拟水足迹呈现盈余即虚拟水出口。Virtual water is a kind of water consumption in products and services, so virtual water footprint can be used to calculate water footprint of urban and rural areas in Tibet and both virtual water footprints were analyzed in this paper.The results showed that the common trends of both water footprint were rising before 2006 and reducing after 2006.The majority of rural virtual water footprint is virtual water consumption of agricultural products and the majority of urban virtual water footprint is virtual water consumption of animal products.And it is found that the virtual water footprint of urban and rural residents in Tibet present a surplus through the water footprint profit and loss analysis, which means the virtual water outlets.
