中文摘要：

建立基于集对分析法城市水安全评价模型,为城市水安全的评价及管理提供决策和支持。根据城市水安全的实际出发,构建了城市水安全评价指标体系及评价等级标准,并由专家法确定评价指标权重,进而利用集对分析法建立城市水安全评价模型,将该模型应用的甘肃省14个地州市水安全评价中。评价结果表明,甘肃省14个地州市的水安全形势不容乐观,安全等级整体偏低。最后,将本文的评价结果与模糊综合评价法和水贫困指标评价法的评价结果进行比较。三种评价结果的对比分析表明,利用集对分析法与其他两种方法得到的评价结果基本一致。该方法可以清晰地反映影响城市水安全因素及其相关特征,且该方法概念清晰,结构简单,计算简洁,易操作。

英文摘要：

The set pair analysis（SPA）model was established in this study to evaluate urban water security.It provides decision support for the urban water management.From the reality of urban water security,this study constructed urban water security evaluation system and evaluation grade standards.The expert method was adopted to get evaluation index weights.Then the SPA method was used to construct urban water security evaluation model.This model was used in water security evaluation of 14 cities in Gansu Province.The results show that the water security state in the 14 cities in Gansu province were not so optimistic.The overall state was low.Finally,the evaluation results were compared with the results got by Fuzzy Comprehensive Evaluation method and Water Poverty Index method.The comparison shows that the results got by SPA method are consistent with the results the other two methods.Meanwhile,this method has the factors and relevant features which clearly reflect the urban water security state.It also has simple structure,simple calculation and easy to operate.
