| 摘 要： | 本文利用水足迹对北京市水资源占用进行估计,得出2006年北京市水资源实际占用量为138.28×108m3,能更真实反映北京市水资源实际占用情况。从产业结构及消费构成分别分析了水足迹的情况,得出农作物和动物产品虚拟水消耗是水足迹消费的主要组成部分,粮食及肉类是耗用水资源的主要消费产品。北京市水资源压力为1.37,工业用水、生活用水、农产品引进、生态环境保障、动物类及农作物产品用水相应水资源压力分别为:0.082、0.135、0.570、0.016、0.350和0.213。市外引入水资源高达59.78×108m3,对外依存度为0.43,说明北京市本地水资源难以满足社会、经济发展需求。分析北京市水足迹组成及水资源保障情况得出结论,市内用水结构优化、虚拟水引进及南水北调是水资源安全保障的基本措施。 |

| Abstract: | A concept of water footprint was developed and elaborated in the present work in order to offer an indicator depicting water use with regard to consumption of people. The water footprint of a city is defined as the volume of water needed for the production of goods and services consumed by inhabitants in the city. The water footprint primarily contains industrial water, domestic water, agricultural water as well as environmental water. The domestic water, environmental water and the part of industrial entit... |
