摘　　要：若尔盖湿地是我国最大的泥炭沼泽地,自然资源丰富。黑河与白河是该湿地中最大的两条河流,黑河与白河流域的水文模拟研究对于了解流域内的水文变化情况具有重要意义。利用黑河若尔盖水文站和白河唐克水文站2009-2016年的实测水文数据,对黑河与白河流域进行SWAT水文模拟。结果表明:唐克站率定期的决定系数R^(2)和纳什效率系数E_(ns)分别为0.79和0.73,若尔盖站率定期的R^(2)和E_(ns)分别为0.72和0.72;验证期唐克站和若尔盖站的R^(2)分别为0.77和0.62,E_(ns)分别为0.72和0.61,模拟结果比较理想;SWAT模型在黑河与白河流域有较好的适用性。The Zoige wetland is the largest peat swamp in China and is rich in natural resources.The Heihe River and Baihe River are the two largest rivers in the wetland.The hydrological simulation of the Heihe River and Baihe River Basins is of great significance for understanding the hydrological changes in the basin.In this study,the SWAT hydrological simulations of the Heihe and Baihe River basins were carried out by using the measured hydrological data from the Heihe Zoige Hydrological Station and the Baihe Tangke Hydrological Station from 2009 to 2016.The results show that the regular decision coefficient R^(2)and the Nash efficiency coefficient E_(ns)of the Tangke Station rate are 0.79 and 0.73 in the calibration periods,and the R^(2)and E_(ns)of the Zoige Station rate are 0.72 and 0.72 in the calibration periods,respectively.In the validation periods,the R^(2)of the Tangke Station and the Zoige Station are 0.77 and 0.62,respectively,and the E_(ns)are 0.72 and 0.61,respectively.The simulation results are ideal.It shows that the SWAT model has good applicability in the Heihe and Baihe River basins.
