水电开发下的河流生态系统管理

水电开发对河流水质、水文情势、泥沙等物理化学状况有着较大的改变，从而引起其中的水生生物及整个河流生态系统的重新调整，影响河流生态系统服务功能的正常发挥。探讨这些影响并对河流生态系统进行正确的管理，关系到河流生态系统甚至整个流域的可持续发展。本文简述了河流生态系统管理的发展过程以及水电开发对河流的影响，并针对这些影响，总结了对应的河流生态系统管理方法，为水电开发下河流生态系统的科学管理和促进流域可持续发展提供参考。

River Ecosystem Management in Hydropower Development

Hydropower development results in great changes in water quality,hydrological regime,sediment and other physiochemical aspects,and causes the readjusting of aquatic organisms and even the whole river ecosystem,which affects the normal rivers ecosystem services.Scientific research on these changes and effects and the river ecosystem management is essential for the sustainable development of river ecosystem and even the whole watershed.In this article,the history of river management and the impacts of hydropower development on river ecosystem are summarized briefly.Aiming at these impacts,the corresponding methods for river ecosystem management are proposed,which can offer the theoretic bases for scientific management of the river ecosystem in hydropower development and sustainable development of the whole watershed.
