%X Ecological and environmental water requirement has been one of the research foci of eco-hydrology in the world.Research on ecological and environmental water requirement of river system has been specially emphasized abroad.In some researches, minimum or optimal flow has been determined according to relations between the protected fishes and physical and flow regimes of river using hydrological or hydraulic methods.Since 1990, ecological water requirement of the river system has been estimated on the concept of ecologically acceptable flow regimes to maintain the integrity of ecosystem.In China, the research on ecological water requirement can be separated into two phases.From 1988 to 1998, ecological water requirement and relative concepts began to be recognized.Since 1998, the concepts have been developed and put into application though it is still far to go.For further research, to develop the theories of ecological water requirement estimation and the transitions mechanism between different temporal-spatial scales of ecological water requirement utilizing isotope and RS technique are important research fields.
