Abstract: Taking Qingyuan Manchu Autonomous County(hereinafter referred to as Qingyuan County) in Fushun City, Liaoning Province as an example, the structural status and existing problems of river embankments in the county were systematically analyzed. The total length of the embankments in Qingyuan County is about 185.6 km, of which 42.3% of the river sections meet the design standard of a 20-year return period, and 57.7% of the small and medium-sized river sections still have low design standards. Using the Analytic Hierarchy Process(AHP) and Fuzzy Comprehensive Evaluation(FCE) models, the stability index(S) of typical embankments was found to range from 0.68 to 0.85, corresponding to an overall rating of “Good.” The Governance Priority Index(GPI) of the downstream Liuhe River and Chaihe Town sections was highest(0.22～0.23), indicating areas requiring prioritized management. Further analysis using the Coupling Coordination Model(CCM) revealed coordination degrees(D) between 0.76 and 0.89, with an average of 0.82, indicating a “Well-Coordinated” relationship among flood safety, ecological function, and economic input. Based on these findings, integrated engineering and non-engineering measures such as the “filter layer + cutoff wall” strengthening method,“ecobag + gabion cage(double-twisted hexagonal wire mesh gabion)” flexible slope protection, and digital monitoring platform are proposed. The results provide a quantitative reference for determining management priorities and developing sustainable eco-flood control systems.
