舟山群岛普陀樟天然群落特征研究

摘要

对普陀樟天然林群落结构和物种多样性进行调查分析,结果表明:普陀樟天然林群落的物种多样性较为丰富,与普陀樟混生的植物种类有46科72属91种,而且层次性较强；6个普陀樟天然林群落桥木层中,普陀樟为下层木存在时和上层木存在时群落相比,Simpson多样性指数、Shannon Wiener指数、均匀度指数相对较高；普陀樟作为上层木时的群落属于常绿阔叶林,作为下层木时的群落为常绿阔叶混交林.%Investigations were conducted on community structures and species diversity in natural Cinnamonumjaponicum var. chenii communities in Zhoushan Islands, Zhejiang province. The results showed mat mere are 91 species plants belonging to 46 families and 72 genera in C.japonicum var. chenii communities with distinguished layers. Simpson diversity index, SHANNON (H) index, evenness index of C. japonicum var. chenii as underwood in six natural forests was relatively high compared with that as overwood. C. japonicum var. chenii community was evergreen broad-leaf forest when C.japonicum var. chenii was overwood, but evergreen broad-leaf mixed forest when it was underwood.
