| 摘 要： | 本对流域状态和最优化特性是如何影响模型功能方面进行了研究．在假设流域诸多初始条件下，使用SCE-UA优化算法通过日模型率定新安江模型．结果发现流域的初始条件和最优化特性对待优化的参数有非常大的影响，并且使模型过程参数的响应程度变小．研究结果表明变化的初始条件对总产流的影响并不是太大．

| Abstract: | An attempt was made in this paper to explore how catchment's states along with optimization characteristics affect model behaviour. The Xin'anjiang model was calibrated under daily forecast mode by using various hypothetical initial conditions of the catchment with the SCE UA optimization algorithm. It was found that initial conditions of the catchment viz a viz optimization characteristics have profound effect on the optimized parameters and to a lesser degree on the model process parameter responses; the result showed that variable initial conditions do not have significant influence on the total generated runoff. |
