摘　　要：黄河流域在中国经济社会发展中具有重要的战略地位,其下游河道水少沙多、水沙关系不协调,具有二级悬河、河势演变复杂等特点,岸坡破坏会严重威胁防洪安全和经济社会高质量发展,因此,保障岸坡稳定、开展黄河下游护坡治理与风险管控十分必要。生态护坡破坏涉及水、土、植被、结构等因素,机理复杂,传统河流动力学理论已不能完全适用,需进一步深入研究。本文总结分析了黄河下游岸坡破坏现状、岸坡失稳机理及其主要影响因素、生态护坡结构研究及应用和护坡工程风险评估及管控等方面现有研究成果及存在的不足,在此基础上探讨和梳理了黄河下游生态护坡未来的一些研究方向,包括揭示水-土-植被等多因素耦合作用下的生态护坡破坏机制、研发适用于强冲积特点的刚-柔协同新型生态护坡结构型式、建立考虑多要素多层次的生态护坡工程风险综合评价指标体系、形成岸坡监测-评估-处置/防护一体化的风险管控技术体系等。The Yellow River basin is of critical strategic importance to China's economic and social development.The lower reaches are characterized by low flow rates and high sediment concentrations,exhibiting an uncoordinated water-sediment relationship.This results in a secondary-perched river phenomenon and a complex evolution of river form.The degradation of bank slopes poses a significant threat to flood control integrity and hinders the economic and social development.Therefore,the preservation of riverbank stability and the implementation of effective slope protection and risk reduction measures are essential.The degradation of ecological slopes is a complex issue,influenced by a synergy of hydrological,pedological,vegetative,and structural stability elements,regulated by intricate processes.The inadequacies of current river dynamics theories necessitate in-depth investigation on this topic.This study compiled the current state of bank erosion in the lower Yellow River,elucidated the factors contributing to slope instability,and assessed the state-of-the-art in ecological slope protection methodologies and the challenges in risk evaluation and management protocols.The study identified key directions for future research in ecological slope protection,including:unraveling the degradation processes under hydro-soil-vegetation interactions;innovating rigid-flexible ecological slope protection structures adapted for intense alluvial conditions;developing comprehensive,tiered risk assessment models for ecological slope engineering;and constructing integrated frameworks for the monitoring,evaluation,and control of riverbank slope integrity.
