摘　　要：针对西北内陆干旱区水资源短缺、农业用水效率低下等问题,通过构建多水源配置模型,融合水肥精准调控技术,研究了农田水利工程水资源优化配置方案。采用“天-空-地”一体化监测系统,结合土壤墒情监测、作物需水规律分析等方法,对灌区农田水分利用效率进行系统评估。试验结果表明:采用浅埋滴灌技术可节水60~80 m^(3)/667 m^(2);水肥一体化智能灌溉系统使水资源利用效率提升25%;通过优化灌溉频率和灌溉量,作物前期灌溉量可降低25~60 m^(3)/667 m^(2)。研究成果为西北干旱区农田水利工程水资源高效利用提供了技术参考。In response to the problems of water resource shortage and low agricultural water efficiency in inland arid areas of Northwest China,the optimization of water resources allocation scheme for agricultural water conservancy project was studied by constructing a multi-water source allocation model and integrating water fertilizer precise regulation technology.Using an integrated monitoring system of"sky air ground",combined with soil moisture monitoring,crop water demand analysis and other methods,a systematic evaluation of the water use efficiency of farmland in the irrigation area is carried out.The experimental results show that using shallow buried drip irrigation technology can save 60 to 80 m^(3)water per acre;that using water fertilizer integration smart irrigation system to increase water utilization efficiency by 25 percent;that by optimizing irrigation frequency and amount,the amount of irrigation per acre can be reduced by 25 to 60 m^(3)during the pre-crop period.The research results provide technical reference for the efficient utilization of water resource in agricultural water conservancy project in the arid areas of Northwest China.
