摘    要:通过间歇供水土壤水分入渗过程的动态模拟,探讨了间歇供水的入渗机理,提出了描述波涌灌效果的指标-后续供水渗速度的折减系数。利用计算机模拟试验的方法研究了灌水技术参数对土壤水分入渗特征参数的影响,给出了各供水段土壤水分入渗特征参数的求解方法,为田面行水流动模拟时入渗过程的描述提供了参数依据。

关 键 词:波涌灌溉  间歇供水  入渗模型  入渗模拟  灌溉

Abstract:By simulating the infiltration of intermittent application dynamically, the infiltra-tion mechanism of surge irrigation and the quantitative index describing the effect of surgeirrigation are studied. The effects of irrigation technique parameters on the infiltration pa-rameters of intermittent application are investigated by the experiments on computer. Theprogram for the infiltration function of different applications is devoloped.
Keywords:surge irrigation  intermittent application  infiltration model  simulating
