| 摘 要： | 以山茶Camellia japonica 所在的阔叶林和灌丛群落为研究对象,通过典型样地调查,对物种组成及多样性进行研究。结果表明,8 个植物群落共调查到维管束植物147 种,隶属于65 科118 属;地理成分多样,热带成分大于温带、亚热带成分,表现为亚热带向暖温带过渡的性质,同时反映出群落所在生境热量条件相对优越。山茶所在的阔叶林群落中,乔木层的丰富度和Shannon-Wiener 指数与演替趋势呈明显的负相关关系,处于岛屿较高海拔的灌丛和疏林,其灌木层和藤本层的丰富度和Shannon-Wiener 指数大于阔叶林;受相应群落乔木层的优势种红楠Machilus thunbergii、青冈Cyclobalanopsis glauca 或台湾蚊母树Distylium gracile 以及更新层的舟山新木姜子Neolitsea sericea 优势突出影响,乔木层与更新层的Pielou 指数波动幅度较大。

| Abstract: | Species composition and diversity of the broad-leaved forest and shrub communities with Camellia japonica were studied based on the investigation of typical plots. The results showed that a total of 147 species of vascular plants, belonging to 118 genera in 65 families, were recorded in 8 plant communities. The geographical elements were various, while the tropical elements outweighed the temperate and subtropical elements,?which showed the transitional characteristics from subtropical to warm temperate and reflected the relative advantage of habitat thermal condition. In communities with Camellia japonica, the species richness and Shannon-Wiener index of the arbor layer presented the significant negative correlation with the succession trend. The species richness and Shannon-Wiener index of shrub layer and liana layer in the higher altitude of shrub and sparse forests were greater than those in the broad-leaved forest. Effected by prominent dominant of the dominant species in corresponding communities, including dominant species Machilus thunbergii, Cyclobalanopsis glauca and Distylium gracile in arbor layer, or dominant species Neolitsea sericea in regeneration layer, the variance of Pielou index of arbor layer and regeneration layer was great. |
