膜孔灌平均入渗水深简化计算模型建立与验证(Simplified Infiltration Model of Film Hole Irrigation and Its Validation)
膜孔灌 入渗速率 膜孔直径
2009/9/11
以非饱和土壤水分运动理论为基础,研究了膜孔灌土壤水分运动的数学模型,并用SWMS—3D软件对多种典型土壤的膜孔灌入渗特性进行模拟,利用模拟结果分析了膜孔灌入渗特性及其影响因素,提出了包含开孔率、膜孔直径的膜孔灌点源平均入渗水深简化模型。采用多种土壤膜孔灌入渗室内试验结果与已有文献资料对所建模型进行验证,结果表明所建模型能较准确地反映膜孔灌点源入渗特性,可为确定合理的膜孔灌灌水技术要素组合提供理论依...
