摘要:
选用目前具有代表性的三水源新安江模型、半分布式TopModel和分布式VIC模型，开展降雨径流模拟计算，分析比较各种水文模型在平原湖区的适用性。选择鄱阳湖未控区间内的博阳河和西河流域，分别进行三个水文模型的参数率定和检验。应用结果表明，VIC模型的效率系数比TopModel模型和新安江模型高出10多个百分点，径流总量相对误差均控制在5%以内，低于其余2个模型。VIC分布式水文模型的模拟结果明显优于集总式和半分布式水文模型，能较好地模拟湖区流域的降雨径流过程和水资源量。The lumped Xin’anjiang model, semi-distributed TopModel model and distributed VIC model were selected for rainfall runoff simulation in order to compare the suitability in the plain lake region. The Boyang and Xi River sub-basins in the Poyang Lake uncontrolled intervening basin were used to calibrate and verify these hydrological models. Application results show that the model efficiency of VIC model is 10% higher than those of Xinanjiang and TopModel models, the relative error of total runoff is within 5% and much better than other two models. The distributed VIC model performs much better than lumped and semi-distributed models and is able to simulate rainfall runoff and water resources well in lake area.
