河流生态与环境用水研究进展

回顾了20世纪80年代以来，国内外在流域生态用水方面的研究进展。在国外，从通过某一生物来确定最小河流流量，到考虑生态系统可接受的流量变化，取得了一定的研究成果。在国内，对生态需水的研究提出了基本的框架，但由于对水生生态环境系统的生化特性、物种关系、食物链、河流和洪泛平原的相互关系等缺乏足够的认识，研究还处于初级阶段。

Advances in Research of Ecological and Environmental Water Consumption of River Basins

Advances in research of ecological water consumption of river basins since 1980 are reviewed. In foreign countries, achievements have been gained from the determination of the minimal flow rate of rivers with a special species to consideration of flow regimes accepted by ecosystems. At home, a framework for research of ecological water consumption is developed, while the research is still in a primary stage due to the lack of knowledge on biochemical characteristics of aquatic ecosystems, food chains, and relationships between species and between rivers and floodplains.
