| 摘 要： | 大孔隙流是土壤优先流的一种,在植被发育区土壤大孔隙比较常见,对径流形成过程产生重要的影响。介绍了大孔隙流的研究方法,系统总结了近50年植被发育区土壤大孔隙对降雨入渗过程及径流形成过程的影响:从水分入渗的角度,大孔隙可以加快降雨入渗过程;由土壤大孔隙流与山坡产流的关系,大孔隙促进了边坡雨水的运动进而引起了快速产流;世界范围内的研究都表明土壤管流或大孔隙流是径流组分重要贡献者。

| Abstract: | Macropore flow is one of the soil preferential flows, and is very common in the vegetation growth area, which shows a significant impact on the runoff formation process. This paper introduced the main research methods of macropore flow, and systematically summarized the effects of macropore flow on rainfall infiltration and runoff formation process in the vegetation growth area during the past 50 years. The results show that the macropore can accelerate the infiltration of rainfall and promote the movement of rainfall over the hillslope that it can result in rapid flow. In addition, pipe flow and macropore flow are the main contributors of runoff components. |
