Abstract: The present invention provides a method for analyzing flow regime alterations from reservoir inflow to reservoir outflow, including: acquiring a reservoir inflow data series and a reservoir outflow data series, and determining a local water year of reservoir inflow and reservoir outflow; calculating low and high pulses thresholds of indicators of hydrologic alteration (IHA) for reservoir inflow, and environmental flow thresholds of environmental flow component (EFC) for the reservoir inflow; applying thresholds required for low pulse and high pulse of IHA and the environmental flow thresholds of EFC to reservoir outflow, and respectively calculating IHA parameters and EFC parameters of the inflow and the outflow; and using the range of variability approach (RVA) based on IHA and EFC to analyze the flow regime alterations from the reservoir inflow to the reservoir outflow according to the IHA parameters and the EFC parameters of the reservoir inflow and the reservoir outflow.
