Abstract：Ecological flow is crucial for sustaining the water ecosystems of rivers and lakes.However,the complex water systems in plain river network areas often pose challenges for traditional ecological flow calculation methods.Therefore,studying the thresholds of ecological flow in plain river network areas holds significant importance.This study focuses on typical rivers in the Jianghan Plain of Hubei Province and investigates ecological flow thresholds in plain river network areas from various perspectives including basic ecology,special habitats,and water environment protection.Diverse and dynamic water demand processes are considered in defining ecological flow thresholds.The results align with reality and provide valuable insights for determining and applying ecological flow thresholds in plain river network areas.
