摘    要:针对黄河中游多沙粗沙区的产流产沙特点,在建立逐网格汇流的水文模型的基础上,构建了逐网格汇沙的土壤侵蚀模型,通过水文模型和土壤侵蚀模型有机耦合,实现了泥沙的产生和汇集的分布式计算。由于模型采用逐网格汇流汇沙的方式进行模拟,使得考虑上方来水来沙对产输沙的影响成为可能。根据研究区的特点,模型在土壤侵蚀过程的模拟中,对重力侵蚀的模拟进行了尝试。经黄河中游小理河流域实测资料验证,模型具有一定的计算精度。

关 键 词:分布式水沙耦合模型  土壤侵蚀  重力侵蚀  沟道侵蚀  汇沙  泥沙  黄河

Abstract:Based on the characteristics of the runoff and sediment production in the middle reaches of the Yellow River,a distributed hydrological model and an erosion model are set up.The hydrological model and erosion model are coupled rationally herein,so the distributed calculation of the yield and transport of sediment are actualized.Because the simulated method of the runoff concentration and sediment transport from grid to grid are adopted in the distributed runoff-sediment coupled model,the effects of runoff and sediment from upslope on downslope erosion process can be calculated.Moreover,the gravitational erosion is calculated with the coupled model.It is demonstrated by the observed data from Xiaolihe gauging station therein that the simulated result of the coupled model is better with a certain calculating precision.
Keywords:distributed runoff-sediment coupled model  soil erosion  gravitational erosion  gullies erosion  sediment transport  sediment  Yellow River
