摘　　要：运用水足迹理论对武汉市2005年～2012年水资源消费项目进行计算,并从水资源结构、效益、生态安全及可持续性能4个指标对武汉市水资源利用情况进行分析,结果表明：（1）武汉市水足迹在研究时段内呈下降趋势,2006年以后水资源利用效率较高,各消费项目中农业产品水足迹所占比重最大;（2）武汉市水资源自给能力很强,单位水足迹承载人口能力呈上升趋势,水资源在武汉市国民经济中产生了较大的经济效益,但对外贡献率较低,且安全状况不容乐观;（3）武汉市水资源利用呈现出可持续发展的状态.The article calculates the consumption of water resources of Wuhan city from 2005 to 2012 by applying water footprint theory,and analyzes the situations of water resource utilization （WRU） in terms of water resource structure,benefit,ecological security and sustainable ability.The results show that：1）the water footprint of Wuhan have declined in the study period,with the WRU efficiency being higher since 2006 and the water footprint of agricultural products ocupying the highest proportion among the consuming items; 2）Wuhan can be self-sufficient in supply water resources,since the population carrying capacity of the water footprint has increased and water resources have made a great economic benefits for the national economy of Wuhan; however,the contribution of the water resource of Wuhan to other areas is low and the security of water resource is not optimistic; 3） the water resources utilization of Wuhan presents the status of sustainable development.
