| 摘 要： | 本文根据水量平衡原理，提出了利用大田畦灌灌水资料推求土壤入渗参数的方法，在此基础上，又提出了利用波涌灌水流推进和消退资料确定间歇入渗减渗率系数的方法。实例计算表明，这些方法能简单而有效地求得田间土壤平均入渗参数和减渗率系数。该研究成果为波涌畦灌技术要素设计和灌水质量评价奠定了基础。

| Abstract: | Based on the principle of balance of surface irrigation water volume, a method for determination of field average infiltration parameter according to the irrigation data is introduced. On this basis, the method for determination of reduced infiltration rate coefficient from irrigation data of surgeflow border irrigation is deduced. The calculation example shows that the method is simple and effective. |
