摘要：对三峡库区栲属群落主要乔木种群的重要值、方差比率、χ2统计量、共同出现百分率PC和联结系数AC等种间联结性指标进行测定。结果表明:小叶栲是三峡库区栲属群落常绿阔叶林的建群种;三峡库区栲属群落19个主要种群的总体种间关联性呈不显著负相关,反映了该群落处于不稳定的演替阶段;19个优势种群构成的171个种对中,12个种对具有显著正相关,7个种对具有显著负相关,而绝大多数种的联结关系未达到显著水平,种对间的独立性相对较强。
Interconnection among the 19 dominant species, 171 species pairs in tree layer of Castanopsis community in Three Gorges Reservoir region was studied by using variance analysis, together with χ2 test, percentage co-occurrence （PC） and association coefficient （AC）. The results indicated that Castanopsis carlesii var. spinulosa was the constructive species of Castanopsis community in Three Gorges Reservoir region. The overall associations between dominant species in the community were not significantly negative, suggesting that the Castanopsis community was not mature and in the phase of active succession. The χ2 test showed that among these 19 dominant species, 12 species pairs exhibited significantly positive association and 7 species pairs showed that significant negative association. However, most of the total 171 species pairs did not show significant interconnection, reflecting that the plant communities tended to distribute independently and still were in the unstable succession.
