摘　　要：根据室内单点膜孔人渗试验资料，研究了充分供水条件下单点膜孔入渗规律及膜孔入渗与垂直一维入渗之间的关系，提出了膜孔入渗的数学模型，建立了膜孔入渗参数与垂直一维入渗参数的关系，实现了根据一维垂直入渗资料确定膜孔入渗模型。该研究成果为膜孔灌溉理论与技术的进一步研究奠定了基础。The paper researches single filmed hole infiltration law and the relation between filmed hole infiltration and vertical infiltration under adequate water supply based on indoor experimental data, suggests the filmed hole infiltration model based on Kostiakov infiltration equation, finds the connection between film hole infiltration parameters and vertical infiltration parameters, and determines the single filmed hole infiltration model according to vertical infiltration data. These research results have laid a foundation for further study of the theory and technology of filmed hole irrigation.
