| 摘 要： | 河流梯级开发在满足社会需求的同时,还对区域生态环境具有一定的作用。针对河流水电开发对生态环境的影响,从河川流量、泥沙输移、水环境以及水生物等几个方面,将国内外的研究状况进行综合评述,并探讨了今后重点研究的几个方面:①如何应用可持续理念指导水资源开发与调度;②水利工程建设对河流水沙变化影响的量化研究;③失衡生态系统的自适应和自恢复机理研究;④水体富营养化最小临界流速研究;⑤如何通过水库联合调度,解决河流水电开发造成的环境胁迫问题的研究。

| Abstract: | The hydro-power developments of a river are favorable to meet the social requirements for water resources and electrical power.But simultaneously,the exploitation of water resource affets the local and regional eco-environment,especially the streamflow,the sediment transportation,the aquatic environment,and the limnobios,and so on.This paper reviews the recently studies on the river-hydro-power development and its impacts on the aforesaid aspects and discusses the significant issues in the further research.These include:(1)measures to adapt water explorations and regulations to the sustainable development theory,(2)quantifying researches on the impacts of hydraulic engineering establishment to the situation of river runoff and sediment,(3)the self-adaptation and self-restoration mechanisms of unbalanced ecosystems,(4)the threshold velocity of the flow for preventing eutrophication,and(5)the methods to deal with river-exploration threats to environment with the co-operation of reservoirs. |
