| 为了探讨流溪河模型在中小河流洪水预报中的适用性，本文以湘水流域构建了流溪河模型.在研究中，根据河道分级的不同分别构建了基于1级河道、1～2级河道、1～3级河道的流溪河模型，采用1场洪水进行参数优选，以50场洪水进行洪水模拟精度验证.研究结果表明，河道分级对流溪河模型模拟精度有较大影响，基于1～3级河道构建的流溪河模型可以很好地模拟洪水过程；采用1场实测洪水进行参数优选的流溪河模型，在实测资料系列不长的我国中小河流洪水预报中应用具有明显优势；研究建立的模型，模拟效果良好，可用于湘水流域的洪水预报. |

| In order to study the applicability of the Liuxihe model in the flood forecast for the small and medium sized watershed，the flood forecasting system based on Liuxihe model in Xiangshui River Basin of Jiangxi province was set up.In the study，according to the classification of different river were constructed based on level 1 channel，1～2 grade，1～3 model of the flow of the river channel；Parameter optimization using 1 a flood；Verified with 50 flood flood simulation accuracy.The results show that the classification has a great influence on accuracy of Liuxihe model simulation，based on level 1～3 channel the flow of river model can well simulate the flood process；The Liuxihe model can effectively optimize the model’s parameters with only one measured flood，thus it takes great advantages in the application of real-time flood forecasting of small and medium sized watersheds in China.Liuxihe model，the simulation effect is good，can be used in meijiang river basin flood forecasting. |
