三峡水库生态调度目标研究

Ecological operation goals for Three Gorges Reservoir

水库生态调度研究是当前国内外河流生态恢复研究中的热点问题。针对三峡水库具体情况,指出了现行水库调度存在的生态问题,进而以水库下游宜昌站作为分析对象,主要从维持天然河道内环境流量和有利于水库下游中华鲟和四大家鱼产卵繁殖的角度,确定了三峡水库生态调度目标,主要包括三峡水库下游河道内环境流量调度目标以及中华鲟和四大家鱼产卵繁殖期水库调度目标。三峡水库生态调度目标的确定可为三峡工程正式运行后制定合理的调度运用方案提供参考。

The research on the reservoir ecological operation is a hotspot problem in the current river ecological restoration research. On the basis of the actul situation of Three Gorges Reservoir （TGR）, the ecological problems of current reservoir operation schemes are pointed out. Taking Yichang hydrological station in the downstream of TGR as a case, the ecological operation goals of TGR are studied from mainly maintaining the environmental flow of natural rivers and protecting the spawning and reproduction of two species fish of Chinese Sturgeon and four major Chinese carps. The study has an important meaning for maintaining the healthy river ecosystem, and the results provide the reference for making the reasonable reservoir operation schemes after the completion of Three Gorges Project.
