摘　　要：本文根据黄丘—副区小流域暴雨洪水特性,应用霍尔顿(R·E·Horton)下渗理论和河网汇流理论建立小流域降雨径流概念模型,采用相关分析提出输沙过程预报模型,并用该区一些代表小流域实测洪水资料对模型进行验证,指出了模型的应用途径。This paper, based on the characteristics of small watershed flood under storms in sub-region No.l of the gullied rolling loess regions, applying Horton's theory of infiltration as well as the theory of flow converging within water system, sets up aconceptual model of rainfall runoff of small water-shed. It also proposes the forecast model for sediment delivery process by related analysis and verifies the model by records of several typical flood data, points out the ways for applying the model.
