中文摘要：

基于洪峰流量和洪水总量之间的相关性及其在洪水分类评价指标中的首要性，以岷江紫坪铺水文站1937～1990年的年最大洪峰流量和最大7d洪量系列为例，应用Copula函数方法构建了其洪峰流量和洪水总量的联合分布模型并将其运用于洪水类型划分，最后对应用中可能涉及的问题进行了讨论。峰量耦合评价方法是具有一定实用价值的一种洪水分类新方法。

英文摘要：

Based on the correlation between flood peak and flood volume and its primacy in the evaluation indexes for the flood classification, a joint distribution model of flood peak discharge and flood volume is established with Copula function method by taking the time series of the annual maximum flood peak discharge and the 7-day maximum flood volume from 1937--1990 at Zip- ingpu Hydrological Station as the study case and then it is applied to the classification of the flood types therein, and finally, the problems possibly related to the application are discussed as well. The evaluation method of coupling flood peak with flood volume is a kind of new method for flood classification with practical application value.
