| 摘 要： | 对于给定的流域，选择合适的水文模型进行模拟是水文学研究的难点。选取中国11个典型流域，划分为蓄满产流区、超渗产流区及混合产流区，分别验证4种经典概念性模型与4种灵活架构模型。研究表明:蓄满产流区灵活架构模型难以提高模拟精度，但可以检验模型构件对模拟结果的影响，排除不合实际的模型结构；超渗产流区灵活架构模型可以提高模拟精度，但缺乏系统性，难以完整准确地描绘水文过程。综合而言，灵活架构模型表现不稳定，通用性差，但架设与修改方便，易于确定流域产汇流关键过程，是水文模拟的有效手段。

| Abstract: | The choice of an appropriate model to be applied to a given catchment for hydrological simulation is a challenging task in hydrology research. To address this issue, extensive research efforts have been devoted to the use of flexible-structure models in recent years. Four typical conceptual models and four flexible-structure models were applied to eleven Chinese catchments divided into the saturation excess, infiltration excess and mixed runoff generation regions. The results show that, in the saturation excess runoff generation region, it is difficult to improve the simulation accuracy by using the flexible-structure models. However, these models can be used to investigate the effect of model components on the simulation results and remove unreasonable model structures for this region. Although the flexible-structure models are able to produce the improved simulations in the infiltration excess runoff generation region, they present less systematic characteristics and cannot accurately represent full hydrological processes. Generally, the flexible-structure models exhibit unstable performance and poor versatility. However, these models are easy to build and modify, and have contributed to the identification of key processes of the runoff generation and concentration. Therefore, the flexible-structure models can be used as an efficient and robust tool for hydrological simulation. |
