| 摘 要： | 滴灌条件下供水强度大于土壤入渗速率时,地表产生积水区,滴灌条件下地表的积水区与土壤质地和滴头流量有关,且积水区的运移是规律的。当供水与入渗达到平衡状态时,积水区稳定。通过试验,研究不同土质在相同滴头流量下积水区运移规律,同种土质在不同流量条件下积水区运移规律,分析其影响因素,得到滴灌条件下积水区的运动符合幂函数关系。 |
| 关 键 词： | 积水区 平衡 运移规律 垂直入渗率 稳定入渗率 |

| Abstract: | Drip irrigation water under the conditions of strength greater than the soil infiltration rate,water surface area generated.Drip irrigation water under the earth's surface area and the soil texture and dripping flows related to the migration and the water district is in line with the law.When the water supply and infiltration reach to equilibrium,the water is stable in the zone.Through the experiment,different soil water in the same area under the dripping flow migration laws,the same kinds of soil in the catchment areas for different flow conditions,migration laws.Analysis of its impact factor,under drip irrigation the water district sports meet the power function relationship. |
| Keywords: | catchment balance migration law vertical infiltration rate stable infiltration rate |
