摘　　要：基于水利工程影响下的产漂流性卵鱼类繁殖需求分析,开发了一种面向产漂流性卵鱼类繁殖的水电站生态水文过程调控方法,通过同步滚动调整启动时机和变动出库流量增幅来人工制造生态脉冲;在确定调控原则和目标的基础上,提出了水电站生态水文调控模型,并进行模型求解;在金沙江中游河段目标鱼类繁殖所需生态脉冲过程、中长期来水预测已知的前提下,将模型应用到梨园水电站生态水文调控实践,结果显示与模型类似工况的求解结果相近。实例验证了所提方法的可行性,可为其他已建水电站开展生态水文调控提供参考。This article presents an eco-hydrological scheduling technology for hydropower stations aimed at enhancing the reproduction of fishes spawning drifting eggs.Artificial ecological flow processes can be created by adjusting the startup time and the outflow rate increment synchronously.In line with the principles and targets,an eco-hydrological regulation model for hydropower stations is proposed,and the corresponding solution ideas are then explained.The model was applied to the eco-hydrological regulation practices at Liyuan Hydropower Station based on the required ecological flow processes and mid-and-long-term inflow for target fish breeding in the middle reach of the Jinsha River.Results verifies the rationality and feasibility of the proposed technology,serving as a valuable reference for the eco-hydrological scheduling of other existing hydropower stations.
