中文摘要：
建立了三水源新安江模型和总径流线性响应模型，并应用于广东省的4个小型流域。根据同一流域对不同洪水等级具有不同调蓄能力的特点，提出了分类法率定新安江模型参数；从5个精度度量标准对2类模型的应用效果进行了较深入的对比分析。结果表明，分类法率定新安江模型参数能够得到更合理的参数，有助于提高预报精度，且新安江模型在研究流域的适用性时优于总径流线性响应模型。
英文摘要：
Both three-component Xin＇anjiang Model and total linear response model are established to study their adaptabilities in four small valleys in Guangdong. A classification method of adjusting the parameters of the Xin＇anjiang Model is put forward in this paper according to the fact that the regulation and storage capabilities for different flood classes at the same valley are different. An analysis of simulated results from Xin＇anjiang Model and TLR model are made based on five measures of accuracy. The result shows that estimating parameters of the Xin＇anjiang Model by using the classification method is not only reasonable but also helpful in increasing the precision of prediction, and the adaptabilities of Xin＇anjiang Model in the four valleys are stronger than those of TLR model.
