The species association of 20 dominant species of Castanopsis community in Jiulianshan Nature Reserve was analyzed by variance analysis, χ2 test, association coefficient(AC) and jaccard index(JI). It was found that the overall association between 20 dominant species was not significantly positive. The χ2 test showed that among these 20 dominant species, 3 species pairs exhibited significant positive association, 1 species pairs exhibited highly significant positive association, 1 species pairs exhibited significant negative association, 3 species pairs exhibited highly significant negative association. Most of the total 190 species pairs did not show significant association. The number of significant negative association between high important value species was most, the number of significant negative association between high important value species and low important value species was neutral, the number of significant negative association between low important value species was least. The community was in the phase of succession toward the stable stage.
