摘  要：
针对水利枢纽工程对河流生态系统的影响,基于鱼类产卵期较大时间尺度(月为周期)的河道生态蓄水过程和小时间尺度的场次模拟生态洪水过程2种工况,建立赣江中游万安、石虎塘和峡江梯级枢纽群联合生态优化调度模型,分析生态调度对水库群经济效益的影响。数学模型中生态流量过程为约束条件之一,以水库群发电量最大作为调度目标,求各水电站的流量过程和发电量,采用逐次优化算法(POA)。结果表明,考虑生态调度后,系统总体发电量减少约185万kW·h,减少1.65%,对水库经济效益即总发电量的影响不大,实施水利枢纽群生态优化调度有利于减缓工程对河流生态系统的影响。

摘  要：
Aiming at reduction of negative influences of hydro projects on a river ecosystem, considering long time scale of fish spawning season (cycling monthly) and simulative ecological flood of small time scale, the establishment of an ecological optimization operation model of Wan′an, Shihutang, and Xiajiang cascade hydraulic project in the middle reach of the Gan River was conducted and the impact of eco-regulation on integrated benefit of step reservoir conglomeration was analysed. Eco-flow process being one of constrained conditions in mathematical model, and maximization of generating capacity of the reservoir conglomeration being the regulating target, progressive optimal algorithm (POA) was employed to calculate water flow process and generating capacity. The results showed that ecological factors taken into account, general electric energy production only decreased by 1.85 m kW·h, reducing by 1.65%, and consequently, the establishment of an ecological optimization operation model could assist alleviating negative impacts of hydropower projects to river ecosystem.
