黄河流域因植被覆盖显著恢复，单一超渗产流模式的传统陕北模型已不完全适用该流域。针对此问题，对陕北模型进行改造，引入蓄满产流模式，构建了超渗蓄满相结合的双产流模式陕北模型。分别将传统模型和改进后的模型在黄河中游伊洛河灵口流域进行应用和对比检验，探讨了改进模型的适用性。结果表明，改进后的模型模拟精度更高，更适用于该地区的洪水计算，具有一定的工程应用价值。
Abstract
Due to the significant restoration of vegetation coverage in the Yellow River Basin, the traditional Shanbei Model based on a single infiltration excess runoff module is no longer applicable to this basin. Based on this problem, an improved Shanbei model has been proposed considering the effect of the saturation excess runoff, which constructs a combination model based on infiltration-excess and saturation-excess runoff module. The traditional model and the improved model are applied and compared in the Yiluo River Lingkou Basin of the middle steam of the Yellow River respectively, and the applicability of the improved model is discussed. The results show that the improved model has higher simulation accuracy, and it is more suitable for the flood calculation in the area, which shows a certain engineering application value.
