| 摘 要： | 介绍SIMHYD降水径流模型的结构及计算原理,利用该模型模拟了丹江口以上汉江上游流域的月流量过程,并采用区间分析方法分析SIMHYD模型参数的敏感性。结果表明:SIMHYD模型可以较好地模拟该流域的月流量过程;根据参数敏感性大小可将SIMHYD模型参数归为3类:第1类为敏感参数,如SMSC和SUB;第2类为较敏感参数,如CRAK和K;第3类为非敏感参数,如INSC,COEFF和SQ。

| Abstract: | The structure and principles of the SIMHYD rainfall-runoff model were introduced.The monthly runoff process in the upper reaches of Hanjiang River upstream Danjiangkou was simulated by use of the model.On such a basis,the sensitivity of parameters of the SIMHYD model was analyzed by means of the interval analysis method.The results show that the SIMHYD model can be employed to satisfactorily simulate the monthly runoff process of the study area.The parameters of the SIMHYD model can be classified into three groups:(1) sensitivity parameters such as SMSC and SUB,(2) local sensitivity parameters such as CRAK and K,and(3) non-sensitivity parameters such as INSC,COEFF and SQ. |
