摘　　要：在分析2009-2017年的疏勒河灌溉数据、实测数据和测量疏勒河3个灌区灌溉水有效利用系数的基础上,介绍了疏勒河灌区灌溉水有效利用系数基本情况,并基于斗口水量计量测量监测系统对测算系数进行对比分析,评价灌区灌溉水效率、灌区农业节水灌溉技术推广和信息系统开发的有效性,提出提高灌区灌溉水有效利用系数措施。Evaluation results of actual measurement data of irrigation in 2009-2017 illustrates the water use condition and efficiency of the Shule River Irrigation District, combining with observation of water use productivity coefficient. Comparative analysis of calculation coefficient based on water metering and measuring system at the canal gate may help to assess the efficiency of irrigated water, as well as the effectiveness of technical extension and information system application. Finally measures for the increase of water use coefficient are proposed.
