| 摘 要： | 中小河流域水文预报时,由于流域水文资料缺乏,洪水发生时间短,传统的水文模型难以取得良好的效果.基于平通河流域研究了分布式水文模型DHSVM的建立过程、建模方式以及模型的结构和参数,探讨了分布式水文土壤植被模型在平通河流域的适用性.并结合平通河水文资料进行了数值模拟研究.结果表明,采用DHSVM模型能够较好的反映流域日径流水文过程,模拟的相对误差均在10%以下,模型在平通河流域具有一定的适用性;从模型的结构角度对结果产生的误差进行了探讨.

| Abstract: | Due to lack of hydrological data and the short time of flood’s concentration,the traditional hydrolog-ical model is difficult to obtain good simulation results in the prediction of medium and small river basins.To analyze the adaptability of DHSVM in Pingtong River basin,modeling process,modeling method and the structure and parameters of the model are researched.Then the numerical simulation is performed combining with the Pingtong River’s hydrological data.Results show that the simulated daily runoff shows general a-greement with the observations;the relative error is all below 10%;the model can be used in the Pingtong River basin.The research work of relative error generated from the simulation results is done. |
