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。
On the basis of a comprehensive survey, the more complete ancient Moso community of Taiwan mosquito trees and the more intact Phyllostachys praecox community near Yiyunan are selected as the study sites. Thirty species of Mosquito community in Taiwan and 30 species of Lohan Twenty-three species of Pinus thunbergii community were selected as study objects. The variance ratio, χ2 statistic and Spearman rank correlation index were used to analyze the interspecific association and correlation among the two ancient tree communities. The results showed that: (1) There were not significant positive associations among 30 species of Mosquito community in Taiwan, and the interspecific relationships were relatively loose; 23 species of Podocarpus pratense community had significant positive associations as a whole, and the interspecific relationships were close. 2 The ecological habits, habitat requirements and the complementarity differences of the vertical structure on habitat requirements are the main factors that determine the species-to-species relationship of these two ancient tree communities. The origins of the community and the habitats of the community are the two old trees The main reason for the existence of interspecific relationships of different degrees in the community. This study has important reference value for the formulation of in situ conservation measures for these two ancient tree communities and the restoration of natural vegetation on other islands in Zhoushan.
