采用2×2联列表，通过方差分析、χ2检验、联结系数AC值、JI指数对江西九连山栲属Castanopsis群落样地重要值前20的种群种间联结进行定量分析。结果表明，九连山栲属群落20个优势种群总体种间的正关联性不显著；但20个优势种群的种间联结关系中3对具显著正联结，2对具极显著正联结，1对具显著负联结，3对具极显著负联结。190个种对中，大多数种对联结关系未达显著水平，种对间的独立性相对较强。种群间的正联结性与种群重要值的关系分析表明，重要值高的种群间形成明显正联结性的种对数量最多，重要值高的种群与重要值低的种群之间形成明显正联结性的种对数量次之，重要值低种群间形成明显正联结性的种对数量最少。目前，群落正处于向顶级稳定群落演替的状态。
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.
