摘　　要：在建立既包括水量损失又包括水头损失的渠道输水效率概念及计算方法,以及将泵站和渠道作为整体建立站渠系统调水效率概念及计算方法的基础上,针对站渠系统普遍实行的调水与供水相结合的运行方式,提出该方式下站渠系统效率的计算方法,并初步分析了影响系统效率的相关因素。A concept and calculation method with consideration of loss of water volume and water head were developed for water conveyance efficiency. Aiming at a combinedwater diversion and water supply operation pattern, which is generally adopted in pumping station-canal system, the conception and calculation method of water conveyance efficiency of the pumping station-canal system were proposed. Finally, some factors influencing the efficiency of the pumping station-canal system were analyzed.
