摘　　要：为了改善畦灌灌水质量,基于畦灌的水流运动过程及入渗水分的空间分布,分析了畦灌灌水效果评价指标灌水效率Ea、储水效率Es和灌水均匀度Ed间的相关关系,并以灌水效率与灌水均匀度之和Ead为目标函数,利用灌水效率Ea、畦长L及比例系数k构造约束条件,建立了畦灌灌水技术参数的实用优化模型。在此基础上,以山西省汾东灌区北长寿灌水试验点为例,将优化模型与地面灌溉模拟软件Win SRFR结合使用,对优化模型进行验证,通过对优化灌水技术参数组合下灌水效果指标进行分析,表明该实用优化模型可实现灌水技术参数的优化选取。In order to improve the border irrigation water quality effectively,this paper is based on the characteristics of surface water movement and infiltration distribution of border irrigation,analyzed the relationships between irrigation application efficiency Ea,storage efficiency Esand distribution uniformity Ed,selected Eadas the objective function,and irrigation efficiency Ea,length of border fields L and proportional coefficient k as the constraints and established a practical optimization model for technical parameters of border irrigation.Moreover,in order to verify this optimization model,this paper integrated the model with the surface irrigation simulation software of Win SRFR,and irrigation experiments of Beichangshou at the eastern Fenhe River irrigation area in Shanxi Province as the background,the analysis for optimized irrigation technical parameters combinations and corresponding irrigation indexes indicate that the optimization model can be used for irrigation technical parameters optimization.
