                Abstract:The  water  resources  system  of  a  river  basin  is  a  complex  system  of  meteorology  and  hydrology-water
                network-economy  and  society-ecological  environment.  Under  extreme  drought  condition, ensuring  the  water

                resources security in the river basin should not only focus on the amount of water shortage,but also need to consider

                the process of water shortage damage and the response process. Ensure that the water resources system in the river


                basin  can  be  restored  to  normal  after  experiencing  severe  water  shortage,that  is,have  the  resilience  to  cope  with

                extreme dry water. The resilience means that when facing external shocks such as climate change and drought,the

                system can maintain its function,structure,and service capacity through a series of regulatory measures and dynamic

                responses. This paper utilizes the Yellow River Basin as a case study,examining the dual natural-social response pro⁃

                cesses of water resources within the basin′s system under conditions of extreme low-flow perturbation. The study pro⁃

                poses a 3Rs (Robustness-Resistance-Recovery)resilience framework,encompassing the system′s inherent stability

                (robustness),its capacity to withstand short-term pressures (resistance),and its ability to gradually recover to a



                                                .
                normal  state  post-disturbance (recovery)  A  comprehensive  16-index  evaluation  system  was  constructed,and  the
                water resources system resilience was quantified using an improved TOPSIS model with combined weighting for the
                period  from  1990  to  2022.  The  Mann-Kendall  test  revealed  that  both  the  connotation  and  coupling  effects  of  the
                system exhibit a significant upward trend. Based on large systems theory,key drivers of water resources system resil⁃

                ience evolution in the Yellow River Basin were identified through a combination of geo-detectors and the K-Means
                clustering algorithm. The identification results were validated through global sensitivity analysis,leading to recom⁃

                mendations for enhancing the basin′s water resources system resilience. The study analyzes and proposes regulation
                strategies for the Yellow River Basin to cope with extreme water depletion,considering scenarios of regulatory mea⁃

                sures from both the supply and demand sides. The research provides theoretical and technical support for constructing
                a resilient Yellow River Basin and improving water resources security in the basin.
