摘要
为研究海河流域下垫面变化对洪水的影响,对新安江模型进行修订,得到新安江-海河模型。选择海河6个典型流域作为研究对象,分别用新安江模型与新安江-海河模型进行产汇流模拟计算,结果表明:洪水分年代、分量级模拟精度较高,但此时新安江模型参数取值不合理,SM值偏大;新安江-海河模型与新安江模型精度相当或稍有提高,参数取值更加合理。
To study the influence of the underlying surface changes of the Haihe Basin on floods, the Xin＇ anjiang- Ha/he model was developed by improving the Xin＇ anjiang model. Six typical watersheds in the Haihe Basin were selected as study areas where the Xin＇ anjiang model and the Xin＇ anjiang-Haihe model were used to simulate the runoff yield and concentration process. The results show that the accuracy is high when floods are divided with periods and magnitudes and are simulated respectively. The parameters of the Xin＇ anjiang model are unreasonable. For example, the SM value is too large. The Xin＇ anjiang-Haihe model can maintain or improve the accuracy of the Xin＇ anjiang model, and its parameter values are more reasonable.
