%X Castanopsis orthacantha and Castanopsis delavayi forests are the major types of semi humid evergreen broadleaved forest in the area of central Yunnan plateau.The paper discusses the interspecific association of the two communities at Jizu Mountain of Yunnan Province.In the study,there are 215 species pairs correlations expressed in 682 pairs mated by 17 tree species,15 shrubs and 29 herbs.The result shows that :1)The species expressed a positive correlation in the same community,and a negative correlation in the different communities.Four species showed the high positive significant correlation in the Castanopsis orthacantha community,and the other 4 species in Castanopsis delavayi community.2) The level of correlation significance varied at different layers.There are more pairs of high level correlation in tree layer than in shrubs or herbs.3)The numbers varied in pairs of positive and negative correlation of community at different stages or in different habitat.No pairs of negative correlation existed in prime stage,while the pair number of positive correlation and non correlation was roughly equal.However,in the later stage the pairs of positive correlation and non correlation decreased and negative correlations appeared.In the transition zone,negative correlation pairs increased and surpassed in number either of the positive correlations 4) The association index model Ai has advantages of both the qualitative and quantitative model,which can both eliminate the higher values in qualitative models,and reduce data collecting work in quantitative models.As the index of value of species,the generalized abundance is more rationale than the number.
