摘要

Because of distributed hydrological model with lots of parameters, output variables, complicated model structure and highly nonlinear characteristics, therefore, parameter calibration becomes the important and difficult problem in the application and development of distributed hydrological model. The paper couples SCE-UA method with WEP-L model, and parameter automatically calibration in the above Daiying hydrologic station of Haihe River Basin, Nash efficiency coefficient increases significantly. Research result presents sample in the big basin of WEP-L model, and provides import hydrological basic support for water resources and water environment management in Haihe River Basin.
