Abstract：Lancao Reservoir is a crucial component of the flood control system in the Qujiang River Basin.While ensuring regional flood security,it inevitably exerts certain impacts on the basin's ecological environment.To mitigate the adverse effects of project construction and operation on the river ecosystem,it is essential to reasonably determine and release ecological flow.Taking the Lancao Reservoir Project in Sichuan Province as the research object,this paper employs multiple methods to separately calculate the basic ecological flow and sensitive-period ecological flow of the project,and systematically analyzes their coordination with the basin's eco-environmental protection requirements and relevant policy documents.On this basis,the ecological flow for the project is comprehensively determined.Corresponding ecological flow release and monitoring measures are proposed,and reservoir ecological operation design is carried out from three aspects:ecological flow regulation,water level regulation,and water temperature regulation.The research findings can serve as a reference for the determination of ecological flow and the design of regulation measures for large and medium-sized water conservancy projects.
