摘　　要：Streamflow and sediment transport in river ecosystems are crit-ical processes for material movement and energy conversion,intri-cately linked to socioeconomic and riverine biophysical processes such as hydropower development,flood mitigation,reservoir silta-tion,and channel adjustment[1].Streamflow-sediment load(Q-S)relationships are fundamental to improving the assessment and prediction of these riverine processes and flux patterns.Damming has substantially regulated large river systems,leading to a signif-icant decreasing trend in both streamflow and sediment load,resulting in far-reaching impacts on water quality and ecological stability[2].In the context of intensifying hydrological extremes.
