| 摘 要： | 结合时变增益非线性产流模型与水箱模型的概念，建立了一个两层结构的水文模型。上层采用时变增益产流模型模拟地表产流，下层采用水箱模型综合模拟壤中流与地下径流，上下两层分别应用Nash单位线和线性水库调蓄方法进行汇流计算。该模型共有6个参数（产流模型与汇流模型分别包含3个参数）。产流模型参数采用SCEUA全局优化算法自动率定，汇流模型参数采用主观优化方法（即实测资料推求及人工调试）确定。以湖南省长潭河流域为对象进行水文模拟应用研究，结果表明尽管模型结构简单，但是能够取得比较好的模拟效果，说明模型比较可靠。

| Abstract: | Integrated with the concepts of a nonlinear runoff model and Tank model, a two-layer conceptual hydrological model was developed according to the water balance principle. The upper layer was developed for simulation of surface runoff with time-varies plus model, while the lower lay was adopted to simulate the soil water and groundwater with Tank model. Nash unit curve and linear reservoir regulation method were used to calculate the process of concentration. The model only includes six parameters, three in runoff model and three in concentration model. The three parameters of the runoff model were optimized by SCEUA algorithm, while the other three parameters of the concentration model were calibrated by manual work. In the case study of the Changtanhe River basin in Hunan Province, the model was used to simulate the hydrological process. The results showed that the model was fea- sible and reliable even though with such a simple structure. |
