摘　　要：以一类与覆盖粗糙集相对应的形式背景为工具,对概念格属性约简和覆盖粗糙集约简进行研究,结果表明覆盖粗糙集与形式背景之间存在一一对应关系,并且证明了覆盖粗糙集的交约简可化为概念格的属性约简。The relationships between attribute reduction theory in concept lattice and reduction in cov-ering rough set are studied based on the formal context corresponding with covering rough set .The results show that formal context and covering rough set are equivalent in some sense , and the occurrence that join reduction of covering rough set is a kind of reduction theory of concept lattice is proved .

关 键 词：概念格 属性约简 覆盖
