| 摘 要： | 为了验证能量平衡融雪模型在巩乃斯流域的适用性,在天山积雪雪崩研究站开展了模型的应用试验。设置了3个融雪水收集样点,模拟值分别与1号、2号和3号样点观测的日融雪量进行对比,结果表明,1号融雪水收集点的拟合优度系数R2=0.86,体积差Dv=-5.9%;2号收集点R2=0.92,Dv=-3.2%;3号收集点,R2=0.91,Dv=-10.7%,模拟值总量偏高于实测值。较高的R2和较低的Dv值,表明模型达到了比较好的模拟效果,也显示该模型在巩乃斯河流域具有良好的应用前景。 |

| Abstract: | In order to verify the application of the energy balance snow melt model for the Gongnaisi River basin,an experiment of the model was performed in Tianshan Station of Snow Cover and Avalanche Research.There were three snow water collect sites in the experiment.By comparison between estimated snow water equivalent(SWE) and observed SWE of NO.1,NO2,NO.3 snow water collect sites,the results showed that two goodness of fit statistics for simulations,Nash-sutcliff coefficient(R2) and volume difference(Dv) were that R2=0.86,Dv=-5.9%(NO.1 snow water collect site);R2=0.92,Dv =-3.2% NO.2),R2=0.91,Dv=-10.7%(NO.3),respectively.The predictions had been overestimated somewhat.The high R2 and low Dv suggested that the model had good simulation effect and it can be applied in Gongnaisi River. |
