| 摘 要： | 以SWAT模型为研究工具,对该模型在东江流域的3个子流域的适用性进行研究,研究表明,SWAT模型在东江流域3个子流域的适用性较好,校准期（19701975年）日径流模拟和月径流模拟的相对误差Re均在10%以内,日径流模拟的决定系数R2均在70%以上,月径流模拟的决定系数R2均在80%以上,Nash-Suttcliffe效率系数基本达到70%;验证期（19761985年及19962005年）,月径流模拟的决定系数R2和Nash-Suttcliffe效率系数均在70%以上,相对误差Re基本在±20%以内,可以满足该流域的水资源评价与规划的要求。

| Abstract: | The applicability of SWAT model in the 3 subbasins of the Dongjiang River Basin was studied. The result shows that the SWAT model for the 3 subbasins performs well. In the calibration period (1970-1975), the relative errors (Re) of daily runoff simulation and monthly runoff simulation are within 10%, the coefficient of determination (R2 ) of daily runoff simulation are more than 70%, those of monthly runoff simulation are more than 80%, and the Nash-Suttcliffe efficiency (NS) are above 70%. In the validation period (1976-1985 and 1996-2005), R2 and NS of monthly runoff simulation are above 70%, Re of it are almost within ±20%. It can meet the requirements of water resources evaluation and planning in the Dongjiang River Basin. |
