This review synthesizes the global evolution of aquatic ecosystem health research and calls for a paradigm shift from isolated, indicator-based assessment to integrated, watershed-scale governance. Led by Qiuwen Chen from Nanjing Hydraulic Research Institute, the research team argues that aquatic ecosystem health must be understood as a coupled social–ecological and process-based property—linking ecological structure with hydrological and biogeochemical processes, socio-economic drivers, and adaptive governance—rather than as a simple aggregation of water-quality or biological metrics.
