Abstract: An ecological flow determination method for considering a lifting amount a belongs to a technical field of environmental engineering and includes the following steps: collecting, by a collecting device, data needed to calculate an ecological flow; determining, by a calculating device, an ecological base flow; selecting an upper limit and a lower limit of the ecological base flow so as to determine a range of the ecological base flow; verifying the lower limit of the ecological base flow; calculating water demands of landscape wetland, sediment discharge and dilution self purification of three service objects; comparing the water demands of the three service objects so as to determine the lifting amount, and finding out a minimum value and a maximum value to determine a lower limit and an upper limit of the lifting amount in the range; combining the ecological base flow and the lifting amount to determine the ecological flow.
