Abstract: In recent years,the phenomenon of dehydration reduction caused by hydropower stations has attracted much attention.To ensure the ecological flow is the fundamental measure to prevent and mitigate the river dehydration and to maximize the natural restoration of river ecology.However,there are still some problems to be improved in the determination of river ecological flow,including the unclear concept of ecological flow,improper selection of calculation river section and calculation method,which resulted in unreasonable ecological flow at some river sections.This paper discussed the concept of ecological flow,systematically analyzed and put forward the technical requirements of the ecological flow of hydropower station,such as the constituent elements,verification procedure,verification section selection,calculation method selection,etc.,and put forward technical key points and precautions instructions for the verification of ecological flow.

Key words: hydropower station, ecological flow, key points of verification, section selection, calculation method;
