摘要
利用室内充分供水单点源入渗试验资料 ,分析了膜孔灌入渗特性及其影响因素 ,提出了包括土壤质地、膜孔面积和土壤初始含水量在内的充分供水单点源入渗模型 ,并提出了模型参数的确定方法。实例计算表明 。
Based on experiment data of single point source infiltration under adequate water supply, the paper analyses the infiltration characteristic of film hole irrigation and affecting factors, presents a mathematical model of single point source infiltration including soil texture, point source area, and initial soil moisture content, as well as the method of determing model parameters, example calculation used in testing the model shows that the film hole irrigation infiltration model can effectively embody the infiltration behavors and laws of adequate water supply point sources.
