Abstract
The arbor of Michelia chapensis community was analyzed according to group aggregation degree index and field survey.The result showed that the community in vertical distribution displayed stable pyramid-type growth state; in horizontal distribution, the Disperse coefficient (C) ,the clumping index (I), dispersal index (Iδ)and the patch index(M*/(-X)) of community were 0.38, -0.62, 0.18 and 0.99,respectively,and the Cassie R.M.exponent (CA) was less than 0.The Michelia chapensis communities in community displayed an uniform distribution, but the other associated species in this community were fewer and their quantities of individuals were also fewer, and showed scattered distribution.It was stable community and belonged top communitiesin the areas.关键词
