In this study, under the condition that
L
is a completely distributive lattice, a generalized definition of fuzzy subrings is introduced. By means of four kinds of cut sets of fuzzy subset, the equivalent characterization of
L
-fuzzy subring measures are presented. The properties of
L
-fuzzy subring measures under these two kinds of product operations are further studied. In addition, an
L
-fuzzy convexity is directly induced by
L
-fuzzy subring measure, and it is pointed out that ring homomorphism can be regarded as
L
-fuzzy convex preserving mapping and
L
-fuzzy convex-to-convex mapping. Next, we give the definition and related properties of the measure of
L
-fuzzy quotient ring and give a new characterization of
L
-fuzzy quotient ring when the measure of
L
-fuzzy quotient ring is 1.
