摘要
为精细描述增江流域水文循环过程,基于分布式水文模型EasyDHM,实现对增江流域产汇流过程的模拟。首先对EasyDHM模型中的众多产汇流参数进行了敏感性分析,然后对其中敏感度较高的参数进行了优化。经参数优化后,三个断面的水文模拟精度在率定期和检验期均较高,说明EasyDHM模型在增江流域应用良好,可为流域水资源的管理、水资源合理利用以及流域洪水预报,起到科学支撑作用。
For a good description of the hydrological cycle process in the Zengjiang River Basin, based on the distributed hydrological model EasyDHM, this paper simulates the process of runoff and concentration in the Zengjiang River Basin. Firstly, the sensitivity of many confluence parameters in EasyDHM model is analyzed, and then the parameters with higher sensitivity is optimized. Based on the parameter optimization, the accuracy of hydrological simulation of the three sections becomes higher in the period of periodic rate and inspection period. It indicates that EasyDHM model is well applied in Zengjiang River Basin, which can play a scientific supporting role in the management, rational utilization of water resources and the flood forecasting in the basin.
