基于SWAT模型的辽西走廊海岸带无观测资料流域地表径流模拟

Runoff Simulation in Ungauged Basins in Coastal Zone of Liaoxi Corridor Based on SWAT Model

基于SWAT模型和流域水文相似性原理,采用模型参数移植法对辽西走廊海岸带无观测资料流域—狗河流域进行地表径流模拟,取得了良好的效果。该方法不仅有效地解决了水文模型在模型参数移植过程中的不确定性问题,而且为其他无观测资料流域的径流模拟提供了方法借鉴。

Based on hydrological similarity principles and SWAT model,runoff of a typical ungauged basin（Gouhe Basin） in coastal zone of Liaoxi corridior was simulated with model parameters transplantation method.The results of simulation are good.This method can not only effectively solve the problems of uncertainty in the process of model parameters transplantation,but also provide a method demonstration for runoff simulation of other ungauged basins.
