摘要： 小流域水沙耦合模拟概念模型,采用文献[1]、[2]和[4]中提出的概念性坡面产沙、沟蚀产沙、坡面汇沙、沟道汇沙和格林-安普特下渗曲线结构,结合水文学中的概念性汇流计算方法,构成了一个完整的、具有明确物理意义的流域水流、泥沙耦合模拟模型.该模型结构简单,经子洲试验站团山沟三试验场和蛇家沟、团山沟、水旺沟三试验小流域实测资料的模拟检查表明,模型结构合理、效果较好,适合于黄土地区流域.

Abstract: A conceptual flow-sedimentation coupled simulation model for small basins was struc-tured by combining the conceptual equations for interrill and rill-gully soil erosion and tran-sport of the eroded soils which were all described in paper [1] and [2] with a conceptual flowsimulation model which was described in paper [3] and [4].The model was tested in threeexperimental blocks and three small basins and the results showed that the structure of themodel are reasonable and the simulation of flow and sedimentation were very satisfactorycompared to the observed data.
