To accurately evaluate the water resources system resilience in the central and southern regions of Hebei Province, based on the three stages of water resource system disturbance:before, during, and after,18 indicators covering key factors such as natural environment, population, socioeconomy, and technical management were selected to construct an evaluation index system for water resource system resilience in the central and southern regions of Hebei Province, reflecting resistance, recovery, and adaptability. To address the uncertainty and fuzziness in decision-making information, the Pythagorean fuzzy set(PFS) was introduced. By combining PFS entropy measurement and PFS divergence measurement, the indicator weights were determined. The evaluation model for water resource system resilience based on variable Pythagorean fuzzy and VIKOR coupling method was established. The model evaluation results indicated that the water resources system resilience in the central and southern regions of Hebei Province showed an overall upward trend from 2015 to 2023, but was affected by fluctuations in the adaptive subsystem, leading to variations during 2018 2019 and 2021 2022. Although the resilience values of water resources systems in various cities fluctuate, they are generally good, and the resilience values change in different years due to changes in specific indicators.
