Abstract: A 15-year change of interspecific association of zonal vegetation, Cryptocarya community, was studied. The results showed that the composition of dominant species in the community structure was not obviously changed in the 15 years. And there were some changes in the interspecific association. Values of the most positive and negative association coefficiem were seldem. The association coefficient between heliophytes and mesophytes were on the increasing. The differentiation of two sub-associations was much more significant. The results indicate the relative stability of the subtropical zonal climatic community, although passive fluctuation as significant.

Key words: Interspecific association, Succession, Zonal vegetation, Dinghushan, Cryptocarya community
