摘要
以宝库河流域为例,探讨了DHSVM模型在高寒区无冰川流域的适用性。介绍了DHSVM模型的概况、物理过程及数字化资料的收集与处理,并以实测径流对模型进行校正,其中Nash-Sutcliffe模型效率系数与实测径流的相关系数较高,模拟的相对误差较低。对比分析模拟径流与实测径流的变化过程发现,DHSVM模型能较好地反映该流域的日、月径流水文过程,具有一定的适用性。
Taking Baoku River basin for an example,this paper discusses the adaptability of DHSVM model for application to the cold region basin without glacier.The introduction of the DHSVM model,physical process and digital data collection and treatment are described.And then the observed runoff is used to verify the model.The correlation between Nash-Sutcliffe efficiency coefficient and the observed runoff is obvious,and the relative error of simulation is low.The simulated daily and monthly stream flow show general agreement with the observations.It can be concluded that DHSVM can be used to streamflow simulation of this basin.
