The invention relates to an ecological scheduling method for reservoir tail fish habitat protection. The method comprises the following steps: S1, basic data collection: collecting water area ecological hydraulic characteristic parameters of a reservoir tail river reach and ecological habits of reservoir tail river reach protection fishes; s2, establishing a reservoir tail river section habitat suitability evaluation index system; s3, constructing a reservoir tail river reach hydrodynamic model; s4, constructing a hydrological forecasting model and a forecasting scheme; and S5, making an ecological scheduling scheme. The method has the advantages that a habitat suitability evaluation index system is constructed by taking a fish concentrated spawning period as a research period and utilizing hydraulic parameter requirements of fish spawning on an inhabiting habitat, and main scheduling requirements of fish spawning are defined; through the water level flow relation between the main control section and the typi
