摘　　要：作为山西省内工程规模最大的自流灌区,汾河灌区建设初期渠道类型均为土质渠道,直到20世纪90年代建成了具有防渗类型的汾河灌区。灌区内的渠系建筑物经过40多年的运行,出现了不同程度的老化及损坏,甚至有些建筑物存在一定程度的安全隐患,导致汾河灌区渠道的整体输配水效率较低等问题出现,因此对汾河灌区节水改造工程的实施迫在眉睫。从1999年开始历经18年的汾河灌区节水改造工程于2016年年底基本完成了骨干性工程建设。通过对灌溉水利用系数的测算进而对节水改造前后渠道输配水损失量进行分析比较,得出降低渠道输水损失行之有效的办法,从而为灌区节约水资源、提高输水效率提供直接有效的方法。As the artesian irrigation area with the largest engineering scale in Shanxi Province,the Fenhe Irrigation Area was initially constructed as a soil channel,and until the 1990s,the Fenhe Irrigation Area with an anti-seepage type was built.After more than 40 years of operation,the canal buildings in the irrigation area have experienced varying degrees of aging and damage,and even some buildings have a certain degree of safety hazards,resulting in the appearance of problems such as low overall water delivery and distribution efficiency of the channels in the Fenhe Irrigation District.Therefore,the implementation of the water-saving renovation project in Fenhe Irrigation District is imminent.The water-saving renovation project of Fenhe Irrigation District,which started in 1999 and lasted for 18 years,basically completed the construction of the backbone project at the end of 2016.Through the calculation of the irrigation water utilization coefficient and then the analysis and comparison of the loss of channel water transmission and distribution before and after the water-saving transformation,effective ways to reduce the channel water loss are obtained,so as to provide a direct way for the irrigation area to save water resources and improve water transmission efficiency effective method.
