ABSTRACT
Based on the 2 x 2 contingency table, by using multi-species relevance (variance ratio, VR), chi2-test, Ochiai index, Dice index, Jaccard index, t-test of v/x and F-test of Morisita, s index, the interspecific relationships and the spatial distribution pattern between 20 dominants in Kangding Zheduo Mountain of Sichuan province were studied. The results indicated that the interspecific association between dominants of Sinopodophyllum hexandrum community in this area did not show significant association, which suggested that the S. hexandrum community was in mature stage, and showed stronger independency, among total 190 pairs in 20 dominant species, 2 species pairs exhibited extremely significantly positive association, 12 species pairs showed significantly positive association, 6 species pairs exhibited significantly negative association and there were no pairs showed extremely significantly negative association. S. hexandrum in community did not show significant association, which indicates they are independent in community, the spatial distribution pattern of S. hexandrum is characterized by random distribution.
