| 摘 要： | 根据膜孔畦灌大田灌水试验实测资料，研究了膜上水流推进规律，并对膜孔入渗采用Ｋｏｓｔｉａｋｏｖ入渗模型，提出利用膜孔畦灌田面水流推进和观测断面水深资料推求充分供水条件下点源入渗参数的新方法。实例计算表明，该法简单易行，并可消除土壤空间变异性对入渗参数的影响。该研究成果为膜孔灌理论与技术研究奠定了基础。

| Abstract: | This paper studies the behaviors of water flow advance process based on field experimental data, and suggests the film hole infiltration model based on the Kostiakov infiltration equation, and presents a new method of determining single point source infiltration parameters under adequate water supply in film hole irrigation. The example calculation shows that the new method is simple and efficient, and can eliminate the influences of spatial variability. The research results have laid a foundation for further study of the theory and technology of film hole irrigation. |
