Method for determining ecological base flow proportion threshold standard

The invention discloses a method for determining an ecological base flow proportion threshold standard. The method comprises the steps of river section partition classification and non-hydraulic engineering adjustment section ecological base flow proportion threshold standard determination. The method can further comprise the step of determining the ecological base flow proportion threshold standard of the water conservancy project adjusting section. According to the method, the ecological base flow target of the river section can be scientifically and reasonably formulated, so that the phenomenon that the ecological base flow target is too high or too low is avoided, meanwhile, the ecological base flow target of a region without data or with less data can be quickly determined, and a basic support can be provided for ecological scheduling and management of water conservancy projects.
