【 摘 要 】

This paper discussed the feasibility of application the Soil and Water Assessment Tools (SWAT) model in the Yangtze River Basin of Jiujiang. Two statistical indicators were used for model evaluation; i) coefficient of determination (R2) and ii) Nash-Sutcliffe efficiency index (Ens). The software of SWAT-CUP was used to calibrate and validate the model based on the measured data from 2000 to 2015 in JiuJiang hydrological station, which could assist in determining the applicability of the model to the basin. Results indicated R2 being 0.82 and 0.76; Ens being 0.78 and 0.72 in terms of the calibration and verification periods, both of which meeting the requirements, It suggested that the SWAT model could be able to well simulate the Yangtze River Basin of Jiujiang watershed.
