摘　　要：为了给分布式水文模型在陕西省中小流域的进一步推广与应用提供参考,在板桥流域和马渡王流域分别应用TOPMODEL、TOPKAPI以及CASC2D等分布式水文模型对2000-2009年间的洪水进行模拟,从两流域的降雨径流关系、地形指数特征以及土壤植被分布等方面进行了分析。结果表明:在常发生超渗产流的板桥流域CASC2D模型的模拟效果较好,而在蓄满产流发生概率较高的马渡王流域采用蓄满产流模式的TOPKAPI模型表现更优。In this paper, TOPMODEL, TOPKAPI and CASC2 D model were applied to simulate floods in Banqiao and Maduwang watersheds from 2000 to 2009. The results show that the CASC2 D model has better effect in Banqiao watershed. While, the TOPKAPI model utilized a saturated runoff mechanism is more suitable for Maduwang watershed. In view of this phenomenon, this paper analyzed the relationship between rainfall and runoff, the spatial characteristics of topographic index and the distribution of soil vegetation in study watersheds. Through the analysis of the simulation results, the applicability of the hydrological model in these two basins was not only discussed, but also the hydrological runoff laws of these two basins were compared and analyzed. To a certain extent, the influence of comprehensive natural geographic conditions to the calculation results of distributed hydrological models was explained, which was beneficial to the further application of distributed hydrological models in medium and small river basins in Shaanxi Province.
