| 摘 要： | 利用SRM模型对黑河上游三个水文站点控制区2000年的融雪过程进行了模拟,在此基础上探讨高山地区不同水文区域对SRM模型模拟精度的影响.模型以MODIS积雪产品和气象台站数据为输入,结合退水系数进行融雪过程模拟,重点研究不同水文站点控制区域下的模拟精度.结果表明:在气象观测数据相对丰富的莺落峡控制区,模拟的精度较高,拟合优度确定系数R~2=0.795,积差D_v=-2.346%;在气象观测资料稀缺的祁连站和扎马什克站控制区,其模拟精度较差,其中祁连站R~2=-0.233,D_v=-3.277%,扎马什克站R~2=0.517,D_v=-11.128%.此外,地形的复杂程度和植被覆盖类型也会对模型的模拟精度产生影响.

| Abstract: | The snowmelt runoff model(SRM) was used to simulate the snowmelt process in three watersheds in the upper reaches of Heihe river basin in 2000.Our objective was to understand the affect of different watersheds on the accuracy of SRM.MODIS snow covered area products and meteorological stations data were used as input parameters to run SRM.Based on the simulated results,the simulating accuracy were compared between the three watersheds.The results show the the highest accuracy is present in Yingluoxia watersh... |
