| 摘 要： | 水足迹是一个与消费有关的水资源占用情况的综合性指标，它提供了一个更为广泛的视角来认识人们是如何利用水资源的，能够较好地评价区域水资源利用情况．通过引入水足迹的概念和计算方法，初步估算了银川市2007年水足迹情况．结果表明，银川市2007年总的水足迹为16．403×10^8m^3，人均水足迹为1102m^3／a，水资源压力指数为0．93，水资源自给率为0．99，水资源进口依赖度为0．01，过高的自给率和水足迹给银川市的生态环境带来巨大压力．同时，分析了银川市水资源利用状况，探讨了降低水足迹、缓解水资源短缺压力的途径．

| Abstract: | How to alleviate the pressure of water resource is a major issue faced by human being.The water footprint is an indicator of water use that looks not only at direct water use of a consumer,but also at the indirect water use.The water footprint thus offers a wider perspective on how a consumer relates to the use of water systems.In this paper,the concept of water footprint and its calculation methodologies are introduced.We compute the water footprint of Yinchuan city in 2007.The result of water footprint of Yinchuan city in 2007 is 16.403×108 m3,per capita 1 102 m3 available.Water self-sufficiency is 0.99,this is not good for Yinchuan city because in arid region water is very scarce.It also analyses the ways to solve the problem of water scarcity and some suggestions have been put forward on how to alleviate the press of water shortage in arid regions.It is only a preliminary estimate of water footprint of Yinchuan city.Future research on water footprints of Yinchuan city should include more detailed data of water use and get a more realistic figure. |
