摘要

Abstract

The paper discusses the applicability of the GeoWEPP model on the Loess Plateau in China. First, the accuracy of simulated meteorological data produced by the CLIGEN weather generator was examined. Then, the performance of simulated soil erosion by the GeoWEPP model was evaluated. The results show that the simulated meteorological data produced by the CLIGEN weather generator were not only performed a good agreement with the observed data, but also reproduced the distributions of normal and extreme conditions. The absolute errors between the simulated and observed values of both of water yield and sediment yield were lower than 30% . Their coefficients of determination were higher than 0. 90 and the Nash-Sutcliffe coefficients of them were lager than 0. 80, which meant the simulated had a good agreement with the observed.
