摘　　要： 选择粤北连江流域为研究区域,以分布式水文模型SWAT作为模拟工具,对流域内的水文过程进行模拟。利用流域内高道、凤凰山和黄麖塘3个水文站2001—2010年的实测月平均径流量进行敏感性分析和参数率定。以2001—2005年作为校准期,2006—2010年作为验证期,以相对误差(Re)、决定系数(R2)以及Nash-Suttcliffe效率系数(Ens)作为模型适用性的评价指标。校准期3个水文站的月径流量模拟值的相对误差分别是2.72%,5.91%,1.63%,决定系数均大于0.9,Nash-Suttcliffe系数分别为0.97,0.89,0.70,而验证期相对误差分别是2.62%,5.36%,9.32%,决定系数均大于0.9,Nash-Suttcliffe系数分别为0.90,0.69,0.69。各项评价指标均符合精度要求,说明SWAT模型可以用于连江流域的径流模拟。 The hydrologic process was simulated by using the distributed hydrological model-SWAT in Lianjiang basin of northern Guangdong.Based on observed data of the daily runoff which were measured at Gaodao,Fenghuangshan and Huangjingtang gauging station from 2001to 2005,the calibration and sensitivity analysis of the model were carried out.The calibrated model was validated for three gauging stations for a period of 5years（2006—2010）.The simulated monthly streamflow has Nash Sutcliffe efficiency value of 0.97,0.89,0.70for the calibration period for the Gaodao,Fenghuangshan and Huangjingtang stations,respectively.The model can successfully simulate streamflow during validation period with the Nash Sutcliffe efficiency value of 0.90,0.69,0.69and R2 value of 0.94,0.93,0.92for Gaodao,Fenghuangshan and Huangjingtang stations,respectively.The Result showed the SWAT model could be well used for runoff simulation in Lianjiang basin.
