摘　　要：本文建立了判别多年调节水库年末消落水位的决策树,并以乌江上游梯级为实例进行了验证。结果表明,应用该决策树指导乌江上游梯级水库运行调度具有概念清晰、操作简便等优点,多年平均可增加梯级发电量2.66亿kW.h,研究成果已成功应用于生产实践中。A decision tree for analyzing the year-end level of carryover storage reservoir is developed in this paper,and it was verified in a case study of the cascade reservoirs on the upper Wu River in Guizhou province.Results indicate that with this simple decision tree guiding the operation of these reservoirs,their mean annual power output was increased by 266 million KW·h.
