| 摘 要： | 利用多期土地覆盖数据,采用参数区域化方法,建立了SWAT模型主要参数与下垫面特征的关系。结果表明,采用下垫面变化后新的模型参数得到的径流模拟精度普遍高于人工试错法,且下垫面变化最大的年份(1995—1997年)径流模拟的Ens=0.793,R2=0.810,与人工调试结果(Ens=0.639,R2=0.641)相比,精度明显提高,模拟的径流过程更接近实测径流过程。 |

| Abstract: | Based on land-use data from multiple stages,a relationship between the underlying surface characteristics and the key parameters of the SWAT model was built using the parameter regionalization method.A set of new model parameters were yielded by combining the relationship with the altered underlying surface characteristics.The results show that the accuracy of runoff simulation with the new parameters was higher than that with the manual trial and error method.The values of Ens and R2 of the Tangnaihai Hydrological Station were,respectively,0.793 and 0.810,using the regionalization method,and 0.639 and 0.641 using the manual trial and error method from 1995 to 1997,when the underlying surface changed most significantly.The simulated runoff process using the regionalization method was closer to the measured one. |
