摘　　要：水库在发挥巨大社会效益和经济效益的同时,也引发了下游河段生态缺水等生态问题,水生生物尤其是鱼类的生存环境受到了不同程度的影响.鱼类作为水生生态系统中的顶级群落,其种群的动态变化可有效反映水生生物群落与水质状况的整体变化信息.本文从概念辨析、研究方法等方面分析总结了国内外生态流量研究现状,阐明了基于河流天然节律和鱼类习性的生态流量研究进展,探讨了该研究领域存在的问题,并在此基础上提出了基于鱼类生境的生态流量研究方向.Although reservoir demonstrates its huge economic benefits,some ecological environment problems arise like downstream ecological water shortage,making the living environment of aquatic organisms,especially the fish suffered from varying degree of damage. Fish as the climax community in riverine ecosystem,dynamic variations of its population can reflect the whole structural information of aquatic community and water quality. This paper introduces the current researches at home and abroad from the aspects of definition and research method,and focuses on the research on natural rhythm of rivers and fish habitats. In addition,we discuss the problems in this field and present the future research trend of ecological flow.
