中文摘要：

以广东省北江流域的长坝、坪石、犁市、韶关4站以及韩江流域的溪口站和珠江三角洲的流溪河站的洪峰流量频率分析为背景，选用6种常用的频率分布线型（模型）进行分析计算，采用线性矩法估计出模型的参数，分别用较少用于水文的模型选择准则AIC、AICc、BIC和ADC进行考虑历史洪水的频率分布模型的选择。结果表明：4种不同模型选择准则对同一站的洪水洪峰流量频率分布线型的选择结果基本一致，与实际资料拟合较好。6站选择的最优线型虽然传统的皮尔逊3型比较多，但最多的是LN型。

英文摘要：

A case study on the peak discharge frequency analysis of the Changba, Pinshi, Lishi, Shaoguan hydrological station of Beijiang basin, Xikou station of Hanjiang basin, Liuxihe station of the Pearl River Delta in Guangdong province is carry out. Model selection criteria are seldom used in hydrological applications. Four model selection criteria, namely, AIC, AICc, BIC and ADC are used for the selection of the flood frequency distribution model considering historical flood. The L-moment estimation method is applied to the parameters estimation of the six common type of frequency distribution. The result shows that peak discharge frequency distribution selection results of the same station for four different model selection criteria are basically consistent, they fit the real data well. Most selection result of optimal Line type is LN type, although P3 type is often selected.
