摘　　要：针对调水工程对生态环境产生累积效应的问题,从累积影响因子、途径和效果三方面介绍了累积效应的特征,阐述了时间和空间累积效应产生的原因和表现方式,分析了南水北调东线工程13个梯级抽水泵站建设运行造成输水渠道的径流、水温、水质、泥沙和水生动植物等方面的累积效应,并剖析了这五个方面的累积规律和机理,为生态水文调控决策提供了理论支撑。Water transfer project will result in accumulative effects on ecological environment. This paper introduces the characteristics of accumulative effects from aspects of accumulative effects factor, approaches and results. And then the reasons and expression mode of time and space cumulative effects are presented. Besides, it analyzes the accumulative effects on runoff, water temperature, water quality, sediment, aquatic animals and plants in water conveyance canal, which are aroused by construction of 13 cascade pumping stations in east route of South-to-North water transfer project. Finally, it studies inner law and mechanism of these five aspects, which provides theoretical basis for regulating and control of ecological hydrology decision-making.
