为对河北省水资源保障度进行客观、有效的评价，确保水资源自然循环系统在不受人们破坏或者威胁的情 况下能满足国家或区域各方面发展需求的自然保障作用，基于驱动力-压力-状态-影响-响应（driving-pressure-state- impact-response，DPSIR）模型初步构建水资源保障度评价体系，通过收集河北省相关数据，对初选评价指标相关性 分析和筛选，确定水资源保障度评价体系，引入变异系数法和秩和比法组合赋权的 TOPSIS（technique?for?order preference?by?similarity?to?an?ideal?solution）模型，对河北省 2001—2020 年的水资源保障度状况开展综合评价，并对 评价结果进行障碍因子诊断。结果表明：河北省在 2001—2020 年水资源保障度的相对贴近度从 0.217 增加到 0.745，呈现波动式增长趋势，水资源保障度整体趋向于较高状态，这说明河北省水资源保障度状况正在逐步改善， 与响应子系统中的跨流域供水占比提高密切相关；大部分年份主要障碍因子为跨流域供水占比、工业废水化学需 氧量、人均 GDP、生活废水化学需氧量和万元 GDP 用水量等 5 个指标。DPSIR-博弈论组合赋权 TOPSIS 模型对 水资源保障度演进评价具有较好的客观性和适用性，对该地区经济社会和生态环境的发展具有重要意义。
