中文摘要: 年径流丰枯不仅与年径流大小有关，而且与年径流的时间分配有关。传统年径流丰枯分类仅考虑了年径流的大小，忽略了年径流的时程分配对丰枯分类的影响。为此，提出了年径流丰枯分类新方法——集对分析法。集对分析法考虑了径流的大小及其年内时程分配，即将年内12个月的月径流量分别分类并构造分类集合，由分类集合与分类标准集合构造集对，用联系度描述集对的关系进而进行径流丰枯分类。将集对分析法用于金沙江干流某水文站年径流丰枯分类，研究表明集对分析法概念清楚，计算简单，分类结果可信。
Abstract:High and low of annual runoff is related to amount of annual runoff and its distribution in a year. The traditional annual runoff classification only takes into account of amount of annual runoff, and ignores the distribution of runoff in a year. In order to overcome the drawbacks of the traditional annual runoff classification methods, a new approach to runoff classification: Set pair analysis method (SPA), has been proposed in this paper. Both amount of runoff and its distribution in a year have been taken into account in the approach. The key of SPA method is to calculate the connective degree of the set pair which is constructed with the classification set of monthly runoff in a year and the standard set, A case study, the classification of annual runoff at a hydrological station of Jinsha River, has been researched. The results show that the presented method is concise and the results of classification are feasible.
