摘要
为深化对流域水文过程的认识与预测,文章基于SWAT模型构建了水文响应模拟方法,系统模拟了典型流域中的降水、径流、入渗及地下水转化等关键过程。结果表明,模拟径流与实测数据吻合良好,模型精度较高,Nash-Sutcliffe效率系数均值达0.962,显示出良好的动态响应模拟能力,具备较强的推广应用价值。
To deepen the understanding and prediction of hydrological processes in watersheds,this article constructs a hydrological response simulation method based on the SWAT model,systematically simulating key processes such as precipitation,runoff,infiltration,and groundwater transformation in typical watersheds.The results showed that the simulated runoff matched well with the measured data,and the model accuracy was high.The average Nash Sutcliffe efficiency coefficient reached 0.962,demonstrating good dynamic response simulation ability and strong promotion and application value.
