摘要:
本文利用土地利用数据和土壤类型资料,分别建立了流域植被网格参数库和土壤网格参数库,构建了鄱阳湖未控区间流域5 km × 5 km网格分布式VIC水文模型,并提出了水文参数网格化方法。应用结果表明,分布式流域模型的模拟结果略优于集总式水文模型,能较好地模拟区域径流过程和水资源量。在更精细的地形、土壤、植被数据支持下,分布式VIC模型的应用效果会有提升空间。本研究首次把分布式VIC水文模型应用于鄱阳湖未控区间流域,对于湖区等无资料地区的水文模拟分析提供了参考和有效途径。

Abstract: With land use data and soil type data, the grid vegetation and soil parameter banks were estab-lished respectively. A distributed VIC hydrological model with spatial resolution of 5 km × 5 km was applied in the Poyang Lake uncontrolled intervening basin, and a grid parameterization scheme was proposed to calibrate hydrological model. Application results show that the distributed VIC model performs fair better than lumped model, i.e., the distributed VIC model can basically well simulate runoff hydrograph and water resources quantity in this study area. Meanwhile, with the support of more sophisticated terrain, soil and vegetation data, the application results of distributed VIC model will be considerably promoted. This study will provide a reference and ap-proach for hydrological simulation in the ungauged plain lake basin.
