In this paper, we first characterize the convex $L$-subgroup of an $L$-ordered group by means of four kinds of cut sets of an $L$-subset. Then we consider the homomorphic preimages and the product of convex $L$-subgroups. After that, we introduce an $L$-convex structure constructed by convex $L$-subgroups. Furthermore, the notion of the degree to which an $L$-subset of an $L$-ordered group is a convex $L$-subgroup is proposed and characterized. An $L$-fuzzy convex structure which results from convex $L$-subgroup degree is imported naturally, and its $L$-fuzzy convexity preserving mappings investigated.
