摘 要:通过对乌饭树野生群落典型样地的调查,对其植物组成、结构、类型以及各主要种群的相对多度、相对频度、重要值及优势种的分析,结果表明乌饭树野生群落种类组成有45科83属130种。乌饭树一般零散分布于次生林中或成熟林的边缘地带,在成熟林中很难更新,在其群落中为优势树种,各样地的群落种类组成差异较明显,年龄结构显示乌饭树为增长种群。Based on the field investigation on the typical plots in the field community of Vaccinium bracteatum Thunb in Ningbo county of Zhejiang province, the composition, structure, types, relative abundance, relative frequency, important value and the dominant species were analyzed. The result showed that there are 130 species in 83 genera of 45 families in the community. Vaccinium bracteatum Thunb is generally distributed in the marginal regions of the secondary or mature forests, and it is the dominant species in the community. The age structure e of the Vaccinium bracteatum showed that it is the increasing population.
