Abstract:
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.
Key words: C.kawakamii, The vegetation layer, Dominant species, Inter-specific Association
