| 摘 要： | 萨克拉门托(Sacramento)流域模型参数较多,关系比较复杂,要有效地率定其参数,首先应该确定参数的物理范围。按影响土壤蓄水状态和径流变化的敏感程度对参数进行分类,阐述了利用流量过程线或流域特性初步分析估计萨克拉门托土壤蓄水量模型参数初值的方法。在实例中提供了参数优选中的实际处理经验。

| Abstract: | The Sacramento Model has many parameters with complex relation ship.The reasonable physics region of parameters should be determined in order to calibrate effeciently.The parameters of the Sacramento soil moisture model are classified as 5 categories based on the main overall effect that they can have on soil moisture state and runoff response,and the method of initial parameter estimate is described by hydrograph analysis and basin's physical characteristics.The practical experiences were stated in a application example of parameter optimization. |
