摘 要：为了科学、全面地对海绵城市建设绩效进行评价，选取5个一级指标和15个二级指标，采用层次分析法和熵权法相结合的组合赋权法确定评价指标权重，通过识别物元、确立经典域和节域、计算综合关联度得到等级隶属度，建立基于组合赋权法和物元分析法相结合的海绵城市建设绩效评价模型。将该模型应用于郑州市海绵城市建设绩效评价分析，结果表明：郑州市2018—2020年海绵城市建设绩效逐年提升，2020年建设绩效为良好。基于组合赋权法和物元分析法相结合的模型能够克服单一方法确定权重时出现的偏差，从量化的角度解决具有不确定性的复杂评价，且计算简单、操作方便，能够提高海绵城市绩效评价的科学性和合理性。

Abstract： In order to scientifically and comprehensively evaluate the effect of sponge city construction， this paper selected five primary indexes and 15 secondary indicators， and combined analytic hierarchy process （AHP） and entropy weight method to determine evaluation index weights， by identifying the matter-element. It established the classical domain and joint domain， calculated the correlation function values and determined the comprehensive correlation membership grade. The performance evaluation model of sponge city construction based on combination weighting method and matter element analysis method was established. The model was applied to the performance evaluation and analysis of sponge city construction in Zhengzhou. The results show that the sponge city construction performance in Zhengzhou has been improved year by year from 2018 to 2020， and the construction performance in 2020 is good. The model based on combination weighting method and matterelement analysis method can overcome the deviation in determining the weight of a single method and solve the complex evaluation with uncertainty from the perspective of quantization. This model is simple for calculation and easy to operate， and can improve the scientific and rational performance evaluation of sponge city.

城鎮化发展导致城市下垫面硬化范围增大，同时全球气候变化加剧了极端暴雨事件的发生[1]，使得城市在应对突发洪涝灾害时具有脆弱性[2]。根据《中国水旱灾害防御公报》统计，1990—2019年全国洪涝灾害平均每年造成直接经济损失1 522.81亿元。为了减小洪涝灾害损失，我国提出建设海绵城市[3]，2015年以来有30个城市入选国家海绵城市建设试点城市，随后各省也确立了省级海绵城市试点城市。随着海绵城市……
