Abstract: Abstract Analyzing the characteristics of river runoff and its ecological effects provides a crucial foundation for restoring the self-regulation capacity of rivers. However, current research on river ecological runoff is often limited to a single aspect and lacks systematic analysis. This study employs environmental flow components (EFCs), hydrological change indicators (IHAs), ecological surplus/deficit indicators (ES&EDs), and river impact factors (RIs) to conduct a multidimensional and comprehensive quantitative assessment of the Yellow River, where ecological issues are particularly pronounced. The results indicate that the runoff of the Yellow River has shown a decreasing trend from 1960 to 2020, with a significant hydrological mutation occurring in the 1980s. The frequency of river flood events has significantly declined, while flow events have become increasingly homogenized, leading to an ecological deficit as the primary phenomenon. The river has undergone moderate alteration, with impacts intensifying from upstream to downstream, particularly affecting extreme water flow events. Additionally, river biodiversity is gradually decreasing, which is closely related to the river flooding process and the rise and fall of flow. This study concludes that runoff fluctuations can seriously destabilize river ecosystems.
