SWAT模型及SUFI-2算法在秃尾河上游流域径流模拟中的应用
The application of SWAT and SUFI-2 to runoff simulation in Tuweihe (Upper) watershed
摘要
Abstract
Trough building the hydrology, meteorology, landuse and soil databases of Tuweihe (Upper) watershed in the arid and semiarid climate region, the physically-based distributed hydrological model—SWAT 2005 model was employed in this study to simulate the hydrology process and surface runoff in this watershed. The SUFI - 2 method was used to uncertainly analyze, calibrate and validate the results of SWAT simulation. The runoff data from 1977—1983 in Gaoji-abao hydrological station was used to calibrate, and the runoff data from 1984—1989 was employed to verdict the results of simulation. The results of the calibration are: the correlation coefficient ( R ) and the model efficiency coefficient (Ens) of the annual runoff is less than 0.6 (The value of more than 0.6 represents the SWAT model can greatly simulate the study watershed) . As for the monthly runoffs, the correlation coefficient ( R ) and the model efficiency coefficient (Ens) of the annual runoffs are over 0.6 or similar to 0.6. The correlation coefficient ( R2) and the model efficiency coefficient (Ens) of monthly runoff from May to October cover 0.8 or similar to 0.8. Thus, the improved SWAT- SUFI model can be applied to simulate hydrology process and surface runoff of this arid and semi-arid watershed in flood season.关键词
