摘要: 为分析三峡-葛洲坝梯级电站(三峡梯级)生态调度效果及其影响,从保证三峡梯级下游河道生态流量、改善江湖连通和保护生物多样性等方面出发,制定了三峡梯级的生态调度目标,并在常规调度的基础上提出基于人工造峰的生态调度方法,通过多种调度方式的仿真结果,分析了不同来水条件下三峡梯级生态调度的效果,揭示了不同生态调度目标之间的影响以及人工造峰对防洪调度和发电效益的影响。研究成果可为开展三峡梯级生态调度实践提供借鉴。

Abstract: To analyze the efficacy of eco-operation of Three Gorges-Gezhouba cascade hydropower plants (so called Three Gorges Cascades) and its impact, the objects for the ecological operation of Three Gorges Cascades were designed to ensure the basic ecologic flow in the downstream channel, improve river-lake connection and protect biodiversity. In light of these objects, an eco-operation approach via man-made flood based on regular operation was presented.  The eco-operation by different methods were simulated to investigate the efficacy of eco-operation under typical inflow conditions. The simulation results also revealed the interaction among different objects as well as the impact of man-made flood on flood regulation and power generation. The study would be referential for the practice of eco-operation of Three Gorges Cascades.

Key words: Three Gorges cascade hydropower plants, ecological operation of reservoir, ecologic flow, river-lake relationship, man-made flood
