| 摘 要： | 壤中流作为径流基本成分之一已为许多国内外学者所证明，但由于其形成空间—包气带土层的物理性质及其构造的复杂性，以及土壤水运动方程解析法的多维局限性，很难用土壤水运动方程准确地加以描述，本文对包气带土层概化后用饱和下渗理论和非饱和下诊理论分析了等强度ｉ降雨的垂直入渗过程及壤中流的形成过程，继而总结出壤中流的形成机制及其产生的必要条件。

| Abstract: | Many scientists have proved that the soil water flow is a basic compontnt ofthe runoff. It is hard to descrip soil water flow by it's dynamic equation for unsaturated zonewhere soil water flow forms,because the unsaturated zone has complex phisical and struc- tural natures and soil water flow dynamic equation has multi dimensional limitation givingsome simplification to the unsaturated zone,We analysed vertical infiltration process of rain- fuls which had equab intensity i and soil water flow forming process by infiltration theory ofsaturated and unsaturated zones,Then,summarized mechanism and basic conditions of soilwater flow forming process. |
