Abstract: The theory of covering generalized rough sets was studied with L-fuzzy topology. The relative interior and closure operators were defined in L-fuzzy topological space and their basic properties were　discussed. These results can be considered as the fundamental theory of rough sets and L-fuzzy topology.

Key words: covering generalized rough set , rough set, L-fuzzy topology
