| 摘 要： | 应用结合单位线和线性水库汇流改进的TOPMODEL,对拉萨河流域进行水文模拟,并与原TOPMODEL模拟结果进行对比.结果表明,两者都取得了较好的模拟效果,但改进的模型模拟基流更稳定和合理.应用两模型评估拉萨河流域降雨空间差异性对流域径流的影响,改进的模型模拟结果相对稳定.

| Abstract: | The Lhasa River basin is a key region for exploiting water resources in Tibet.However,there are presently few applications of hydrological models to this basin.Modified TOPMODEL with unit hydrograph(UH) and a linear reservoir routing components is applied to the Lhasa River basin for hydrological simulation.Model performance in predicting discharge is assessed for both original and modified TOPMODEL.It was found that both performed well for the basin.However,the simulated baseflow with the modified model is... |
