Overview

Analysis identifies ecological flow changes in a river-lake system, suggesting tailored management strategies.

Key Points

  • The aim is to quantify long-term ecological responses to reservoir operations in a river-lake system.
  • Applied an indicator-based ecological flow assessment in the Jingjiang reach.
  • Analyzed daily discharge records from 2003 to 2024 at key stations and outlets.
  • Utilized a unified ecological flow scoring framework for consistency across sites.
  • Non-flood season ecological flows improved significantly along the Jingjiang mainstem.
  • Flood-season ecological flow scores remained stable under flood-control measures.
  • Outlets demonstrated differing responses influenced by lake storage and backwater effects.
