摘　　要：基于城市内涝发生前、中、后期特征,将韧性理论引入城市内涝治理,构建郑州市内涝韧性体系,利用可变模糊集、贡献度和障碍度建立评估模型,分析了郑州市内涝韧性变化规律及主要影响因素。结果表明:2001—2020年,郑州市初期内涝韧性水平较高,但随着“城市病”逐渐突出,韧性水平由2001年的3.2下降到2020年的2.9,处于可以通过自我调节恢复到原始状态的韧性一般水平;系统层中前期内涝韧性在城市内涝韧性体系中具有重要作用,平均贡献度为41%;城市排水管网是内涝韧性发展中最主要的关键限制因素,平均障碍度为16%;公共交通服务能力等次要限制因素也是提升城市内涝韧性水平不可忽视的一部分,其障碍度之和较关键限制因素高出15%;郑州市城市内涝韧性水平一般,需在城市排水管网等方面加强以提升内涝韧性。Based on the characteristics of urban waterlogging before,during,and after its occurrence,the resilience theory was introduced into urban waterlogging management,and waterlogging resilience system in Zhengzhou City was constructed.An assessment model was established using variable fuzzy sets,contribution degree,and obstacle degree to analyze the changes in the waterlogging resilience of Zhengzhou City and the main influencing factors.The results showed that from 2001 to 2020,the waterlogging resilience level of Zhengzhou City was relatively high in the initial stage.However,as the“urban disease”gradually became prominent,the resilience level decreased from 3.2 in 2001 to 2.9 in 2020,reaching a moderate resilience level that can be restored to its original state through self-regulation.The early stage of waterlogging resilience in the system layer played an important role in the urban waterlogging resilience system,with an average contribution of 41%.The urban drainage network was the most critical limiting factor in the development of waterlogging resilience,with an average obstacle degree of 16%.The limiting factors including public transportation service capacity were also an indispensable part of improving the resilience level of urban waterlogging,and the sum of its obstacles was 15%higher than the key limiting factors.The level of urban waterlogging resilience of Zhengzhou City is average,and it is necessary to strengthen the urban drainage network and other aspects to enhance the resilience of waterlogging.
