| Abstract: | The issue of ecological water demand is one of the hot topics in the world, especially in the arid areas, under the eco-environmental condition deteriorated sharply. Currently, the definition of ecological water demand is various and vague, and the studied ways and methods to many researchers in this field are different from each other. The obtained various concepts and main methods of ecological water demand are summed up in this paper, respectively. Some studying results for arid regions are also analyzed. From the principal part of concepts, the relationships between the ecological water demands, environmental water demand and eco-environmental water demand are differentiated. At the same time, some reviews are made on the key conceptions, theories and ways and methods in the paper. Lastly, the study trends of ecological water requirement in the arid regions are prospected. |
