摘要
为模拟长江三峡库区优先流运动,以Macro模型为基础模型,依据长江三峡花岗岩区试验地特征及观测数据,对模型驱动变量、土壤物理特性参数进行了适当修正,得到了试验地区优先流运动模型。应用EF统计方法对实测结果和模拟结果进行了检验,检验结果表明不同层次土壤中优先流流量的EF统计值均大于0.89,说明所建立的优先流模拟模型能够较好地模拟优先流过程。
Based on Macro Model,and according to the field conditions and observed data in the granite area of the Three Gorges,the boundary conditions,driving variables and soil physical characteristics parameters were suitably corrected,The modified model that was suitable for the Three Gorges area was set up.The simulated results were compared to measured results,and the model was evaluated by EF statistics method.The result of evaluation showed that the EF values of preferential flow were all bigger than 0.89 in different soil layers,which showed that the established preferential flow model could simulate preferential flow process well.
