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.展开更多
