| 摘 要： | 膜孔入渗为充分供水条件下的空间三维入渗,可分为三种类型:膜孔自由入渗、膜孔单向交汇入渗和膜孔多向交汇入渗。在已有研究成果的基础上,综述了膜孔点源入渗影响因素、入渗模型特性、水分分布特征、湿润体浸润形状、湿润锋运移的规律、数学模型等,提出了膜孔灌今后应研究的主要问题。

| Abstract: | Film hole irrigation produces spatial 3 D infiltration under sufficient water supply.The types of film hole infiltration can be classified as single point source infiltration,single-line interference infiltration and multiple-line interference infiltration.On the basis of the past achievements on film hole irrigation,this article summarizes the influential factors of point source infiltration,the features of existed infiltration models,the water distribution characteristics,the shape of wetted body,the moisture front transferring rules and mathematical models.Moreover,some problems about film hole irrigation to be solved are discussed. |
