| Abstract: | This article discusses the reductions in a family of covering,under the condition that the topologies induced by the family of coverings are not changed.By virtue of theory of topology,it explores the theory of reduction in covering generalized rough sets,and presents the method for calculating the reductions.Its results enriches the theory of covering generalized rough sets. |

| Keywords: | rough sets covering topology reduction |
