摘　　要：灌溉水利用系数是表征农业灌区灌溉工程基础和运行管理水平重要的综合性技术指标,本文基于干旱新疆农业灌区灌溉工程和用水管理生产实践,采用投入产出模型农田灌溉用水测验等方法,在分析研究灌区投入与目标产出影响效应,田间灌溉用水定额适宜尺度等技术问题的基础上,提出了改进式灌区灌溉水利用系数测算方法,为进一步探究改进农田灌溉水利用系数测算方式,促进灌溉水资源利用效率评估分析水平提供技术参考。The irrigation water utilization coefficient is an important comprehensive technical indicator that characterizes the foundation and operational management level of agricultural irrigation engineering. Based on the irrigation engineering and water management production practice in arid Xinjiang agricultural irrigation areas, this article uses input-output models and agricultural irrigation water testing methods to analyze and study the impact of input and target output in irrigation areas, the appropriate scale of field irrigation water quota, and other technical issues. Based on this, an improved calculation method for irrigation water utilization coefficient in irrigation areas is proposed, providing technical reference for further exploring and improving the calculation method of irrigation water utilization coefficient in farmland, and promoting the evaluation and analysis level of irrigation water resource utilization efficiency.
