SWAT模型在黄土丘陵区燕沟流域的应用研究
Application of SWAT Model to Yangou Watershed in the Loess Hilly Area
摘要
Abstract
SWAT（soil and water assessment tool）,which is based on physical mechanisms,is a distributed hydrological model developed to simulate and predict runoff in different underlying surfaces accurately.The purpose of this study is to simulate the monthly runoff from Yangou Watershed in the loess hilly area from 2002 to 2008 by using SWAT model.Results indicated that the correlation coefficients in the period of calibration and validation were 0.96 and 0.98 with the Nash—Sutcliffe′s coefficient being 0.89 and 0.76,respectively.The precision of SWAT simulation is higher than the evaluating criterion（Ens〉0.5,r2〉0.6）,which demonstrates that SWAT is applicable to simulate the runoff from Yangou Watershed and practical in flood monitoring and forecasting in the loess hilly area.关键词
