【摘要】 为了探索分布式水文模型在半干旱半湿润地区的应用效果,选用基于物理的分布式水文模型TOPKAPI,研究其在国内中小流域的适用性。选取半湿润地区马渡王流域、板桥流域及半干旱地区志丹流域作为典型研究流域,分析2000年~2010年的8场洪水模拟精度等特征值。结果表明,模型在半湿润地区取得较好的应用效果,验证了模型的合理性和适用性;而在半干旱地区模拟精度较差,适用性不好,但可用于中小河流洪水模拟,基本满足流域洪水预警的应用要求。更多还原

【Abstract】 In order to explore the application effect of distributed hydrological model in semi-arid and semi-humid basins,a physically distributed hydrological model TOPKAPI is chosen to research the applicability in medium and small basins in China. Taking Maduwang Basin and Banqiao Baisn in semi-humid region and Zhidan Basin in semi-arid region as typical study cases,eight flood events from 2000 to 2010 are simulated by TOPKAPI model,and then the simulation accuracy and runoff statistical values are contrasted. The results show that:(a) the TOPKAPI model can be applied to semi-humid region with relatively high accuracy,which verifies the rationality and applicability of model; and(b) the simulation accuracy of TOPKAPI model in semi-arid basin is poor,but it can be used to simulate floods of medium and small basins and can basically meet the application requirement of flood forecasting and warning in medium and small basins.更多还原
