摘要
灌溉水利用系数是衡量灌区工程技术水平状况和管理水平的重要指标。渠道输水损失约占灌溉损失水量的60%~80%,故提高渠道水利用系数是灌区水利设计、灌溉管理、用配水计划编制的重要内容,直接关系到工程设计是否合理、用水计划是否可行、水量分配是否合理。通过分析比较国内外不同国家采用的渠道输水损失计算公式和方法,结合目前灌区的实际情况,对灌区渠道水利用系数的计算和取值进一步分析研究。
Irrigation water utilization coefficient is an important index to measure the technical level and management level of irrigation area.The water loss of canal accounts for about 60%-80%of irrigation loss.Therefore,increasing the water utilization coefficient is an important content of water conservancy design,irrigation management and water use and distribution plan compilation in irrigation area,which is directly related to whether the design is reasonable,whether the water use plan is feasible,and whether the water allocation is reasonable.Based on the analysis and comparison of the water loss calculation formulas and methods in different countries at home and abroad,and in combination with the actual situation of the irrigation area,the calculation and value of the canal water use coefficient in the irrigation area are further analyzed and studied.
