| Abstract: | A review of the recent advancement in the area of water demand of river ecosystem is presented.Different kinds of water demand for ecosystem are classified according to their basic function and target. Methods for calculating the amount of various water demand and their relationship are discussed.On this basis,principles for determining the reasonable amount of river ecosystem and corresponding threshold are proposed.It includes the principle for determining the function of water demand,dynamics, subsection, harmonization,priority,maximization of efficiency,minimization of aftereffect and optimization for whole river section. |

| Keywords: | river water demand ecosystem functions threshold principle |
