| 摘 要： | 基于田间实测的地表水流推进过程 ,利用水量平衡法推求波涌灌溉间歇供水条件下的土壤入渗参数。在此基础上 ,利用地面灌溉模型模拟田间水流推进过程并与实测值作对比后发现 ,与单点入渗测试方法相比较 ,该法不仅具有较高的参数估值精度 ,还具备田间试验工作量相对较小、应用简便等特点 ,具有较好的实用价值。

| Abstract: | Based on water flow advance data observed in fields, infiltration parameters under surge water application were determined with water balance method. The advance phases data simulated with model SRFR were compared with field investigated data for evaluating precision of estimated parameters. Results indicated that the infiltration parameters calculated with water balance method is precision, and that water balance method is more suitable to describe infiltration process than double ring infiltration method under surge water application. |
