To illuminate the niche of Cinnamomum migao community, to understand the utilization characteristics of the community for protecting and managing C.migao, the resource utilization characteristics of the main species in the community were analyzed, with the survey data of C.migao natural forest community in Guizhou Province. C.migao, Maesa japonica and Smilax china, with the largest niche breadths, dominated the community with strong competitiveness and resource utilization ability; the greater the niche breadth was, the greater the niche overlap was. Yet under the same or similar environmental conditions, the species pairs with smaller niche breadth value could also have relatively high niche overlap. The low niche overlap index of main species in C.migao community indicated that the similarity of resource utilization among species was low, the niche of species was clearly differentiated without fierce competition, the community structure was relatively stable, and the species could coexist well.

Key words: Cinnamomum migao, utilization of resources, important value, niche breadth, niche overlap
