摘　　要：在全面踏查的基础上,选取普陀山慧济寺旁较为完整的台湾蚊母树古木群落、逸云庵旁较为完整的罗汉松古木群落为研究样地,以台湾蚊母树群落30个物种以及罗汉松群落23个物种为研究对象,采用方差比率法、χ2统计量以及Spearman秩相关系数指标分别对这2个古树群落木本植物进行种间关联及相关性分析。结果表明:1台湾蚊母树群落30个物种整体存在不显著正联结,种间关系较为松散;罗汉松群落23个物种整体存在显著正联结,种间关系较为紧密。2物种的生态习性、对生境的要求以及垂直结构上对生境要求的互补性差异是决定这2个古树群落种对关系的主要因素,且群落的起源以及群落的生境是这2个古树群落存在不同程度种间关系的主要原因。此研究对制定这2个古树群落的就地保护措施以及舟山其它岛屿的自然植被恢复等具有重要参考价值。We selected Distylium gracile communities next to Huiji temple,Podocarpus macrophyllus community near to Yiyun hut as our study sites after overall reconnaissance in Putuo Mountain. Interspecific associations and correlations over 30 and 23 tree species were studied in Distylium gracile community and Podocarpus macrophyllus community, respectively, by using variance ratio （ VR）, χ^2 test and Spearman rank correlation. The results showed that：there were non-significantly positive associations among species in Distylium gracile community,while significantly positive associations among species in Podocarpus macrophyllus community. These results suggest that species behavior, habitat acclimatization, and complementary differences in habitat requirement in vertical direction might be the main driver affecting species association and correlation in these two ancient tree communities. Difference of interspecific relationships between two communities may be related to community origin and habitat properties. This study provides helpful references for protecting these two ancient tree communities and reclaiming natural vegetation on other Zhoushan islands.
