摘　　要：以2013年苏北地区水资源相关数据为样本,根据水足迹理论构建研究水资源利用效率的综合评价体系,并利用投影寻踪分类法作为研究的主要方法对该体系进行实证分析。结果表明,盐城市用水效率较高,而徐州和宿迁用水效率较低。Based on the relevant data samples of water resources in the northern areas of Jiangsu Province in 2013, a comprehensive evaluation system for water use efficiency is established according to the theory of water footprints. The projection pursuit clustering is employed to analyze the proposed system. The results show that the water use efficiency in Yancheng City is higher,while that in Xuzhou City and Suqian City is relatively low.
