摘　　要：文中首次尝试将集对原理用于频率曲线拟合度的定量评价中,并对安宁河流域德昌站年最大流量频率曲线拟合度进行分析。结果表明,在基于集对原理的频率曲线拟合度的定量评价中,同一性、差异性、对立性的数值能提供更多信息、更多对比,使推断更加合理可行。集对法原理简单,使用方便,灵敏度高,特别是能清晰和形象地显示关系的结构,在分析中具有明显的优势。The principle of Set Pair Analysis（SPA） is attempted to be applied to the quantitative evaluation on fitting of the frequency curve based on the data of the annual flood peak from Dechang Station within Anning River Basin. The obtained results show that the suggested method can offer more information and more comparisons from the numerical values of oneness, otherness and opposition in the quantitative evaluation concerned based on the principle of the set pair, and then can make the relevant de- duction more reasonable. At the same time, the set pair analysis is simple and sensitive, especially can display the structure of the relationship. So it is feasible for quantitative evaluation of fitting of the frequency curve.
