水资源短缺和污染是可持续发展的重要问题。运用模糊综合评价和熵值法建立了基于水足迹指标的水安全评价模型。然后将该模型应用于中国湖南省2006-2016年。首先，分析表明，水足迹指标结合人口事实和经济结构变化能够全面反映水安全状况。结果表明，2006 - 2016年湖南省水足迹增长了16.49%，湖南省水资源安全处于较安全状态。第三，农业水足迹和粮食安全安全等级上升18.4%，这意味着水资源管理效率亟待提高，特别是如果我们考虑到未来十年人口增长的预期。(C)2019爱思唯尔有限公司版权所有。
Water shortage and pollution are important issues for sustainable development. This paper establishes a model for water security evaluation based on water footprint indexes by using fuzzy comprehensive evaluation and the entropy value method. The model is then applied to the Hunan province in China for 2006-2016. First, the analysis shows that water footprint indexes can fully reflect the water security situation when combined with population facts and economic structure changes. Second, the result illustrates that the water footprint increased by 16.49% between 2006 and 2016, and Hunan's water security is in the more than safe situation. Third, a rise of 18.4% in the agricultural water footprint and the safe grade of food security imply that the efficiency of water management needs improving urgently, especially if we consider the expectation of an expanding population in the next decade.
