摘　　要：A series of techniques including the analysis of variance,χ2-test,association coefficient,Ochiai′s coefficient,Czekanowski′s coefficient and Jaccard′s coefficient were used based upon a 2×2 contingency table to determine the overall association of all species,the statistical significance and the coefficient of the each species-pair association of the 48 dominant species in the vegetation layer in \%C.kawakamii\% forest.The results showed the inter-specific association of dominant species in the layer in \%C.kawakamii\% forest can be adequately interpreted by using the techniques mentioned above.The overall association of all species is significantly positive.By \%AC\% values analyzed,464 species-pair are positive and 655 species-pair are negative,and the others are fully independent.1128 species-pair were checked by χ2-test,in which 27 species-pair were observed to have significant positive association at \%P\%=0.01,18 species-pair at \%P\%=0.05 and 17 species-pair revealed significant negative association at \%P\%=0.01,94 species-pair at \%P\%=0.05.The results still showed only 5 species,such as,\%C.tibetana,S.tzumu,C.fabri,C.subavenium\% and \%H.fragrans,\%are significantly negatively related with C.kawakamii,which is relatively weak with the other majority species in the layer in \%C.kawakamii forest.
