摘　　要：讨论基于覆盖理论的S-粗集模型的性质,给出了S-粗集生成的拓扑结构,证明了覆盖S-粗集模型与自反、传递关系下的S-粗集模型是等价的。This paper is devoted to the study of the covering S-rough set model. The topological structure of the corresponding S-rough sets is established and the equivalence between covering S-rough set model and reflexive, transitive relation based generalized S-rough set model is proved. Also, the axiomatic description of covering S-rough set model is given.
