摘要:

对舟山群岛和大金山岛普陀樟(Cinnamomum japonicum)群落的种类组成、外貌、结构特征与动态及物种多样性进行分析。结果表明:(1) 在700 m2样地中,有维管束植物71种,隶属于46科63属;该群落以普陀樟、朴树(Celtis sinensis)、天仙果(Ficus erecta var beecheyana)、红楠(Machilus thunbergii)为优势种;群落外貌终年常绿;多数优势种种群处于增长状态;(2) 群落物种丰富度Margalef指数为99917,ShannonWiener指数为30657,Simpson指数为09007,均匀度指数为07192,该群落的层次格局为:草本层>乔木层>灌木层;(3) 与其他4个不同群落比较,普陀樟群落的物种多样性略低。

Abstract:

The composition, physiognomy, structure and dynamics characteristic, species diversity of the Cinnamomum japonicum varchenii community were studied based on community investigation. The results showed that 71 species in 63 genera 46 families of vascular plants were recorded in 7 plots in total of 700 m2. The analysis on species important value showed that Cinnamomum japonicum varchenii, Celtis sinensis, Ficus erecta varbeecheyana, Machilus thunbergii are dominant species of the community. The physiognomy of the community is ever green all year around. The age structure of dominant populations showed that three out of four main populations of the community are increasing populations. The species diversity of the community is measured with the Margalef index of 99917, the ShannonWiener index of 30657, the Simpson index of 09007, and the evenness index of 07192. The diversity pattern from maximum to minimum is herb, arbor, shrub. Diversity comparison with 4 other different communities showed that the species diversity of Cinnamomum japonicum varchenii community is slightly lower.
