以台州绿心区内6个典型的森林群落(Ⅰ.枫香+榆树+朴树、Ⅱ.朴树+枫杨+马尾松、Ⅲ.无患子+乌桕+柏木、Ⅳ.枫香+三角枫+柏木、Ⅴ.朴树+大叶女贞+马尾松、Ⅵ.香樟+无患子+三角枫群落)为研究对象,采用Shannon-Wiener(H)、Patrick丰富度(R1)、Margalef物种丰富度(R2)、Pielou均匀度(J)、生态优势度(D)等5个指标分析森林群落的物种多样性。结果表明:1群落内植物资源较为丰富,共计31科40属50种,其中乔木层植物19种,灌木层植物22种,草本层植物种类稀少,仅9种;2乔木层和灌木层的物种丰富度和多样性指数显著高于草本层,但不同群落的同层次间各指数差别不大,均未达到显著差异;36个群落的物种丰富度与群落多样性总体表现为:Ⅵ群落>Ⅰ群落>Ⅱ群落>Ⅳ群落>Ⅴ群落>Ⅲ群落。
Six typical forest communities in the green heart of Taizhou (Ⅰ. Liquidambar formosana + Ulmus officinalis + Hackberry tree, Ⅱ. Hackberry tree + Pterocarya stenoptera + Masson pine, Ⅲ. Cypress, V. hacki + P. virginiana + Pinus massoniana, V. camphostella + S. trifoliata) were studied by Shannon-Wiener (H), Patrick abundance (R1), Margalef species richness (R2), Pielou evenness (J) and ecological dominance (D) were used to analyze the species diversity of forest communities. The results showed that: (1) The plant resources in the community are rich, accounting for 31 families, 40 genera and 50 species, including 19 species of tree layer, 22 species of shrub layer and few species of herbaceous plant, only 9 species. 2 Species of tree layer and shrub layer The richness and diversity index of the 36 communities were significantly higher than that of the herb layer, but the differences among the different communities were not significant at the same level. The species richness and community diversity of the 36 communities showed as follows: Ⅵ community> Ⅰ Community> Group II> Group IV> Group V> Group III.
