摘  要:
该研究通过对米槠天然次生林的样地调查,计算其多样性指数,对乔木层物种数量特征、径级分布、高度级分布进行分析,并比较了不同样地间的树种多样性。结果表明:米槠占据顺昌县米槠天然次生林群落优势地位,其径级分布符合一般天然林径级分布规律,其乔木层树种与株数随径级的增加而降低,林分中主要树种分布于中间高度级4~8m,群落物种均匀度指数、多样性指数和生态优势度指数分别为0.67、1.70和0.39,天然次生林群落整体处于稳定演替阶段。

摘  要:
According to the investigation about the natural secondary forest sample of Castanopsiscarlesii(Hemsl)Hay,by evaluating the diversity index,analyzing the quantitative characteristics,the distribution of diameter classand altitude class,and comparing the species diversity of different samples,the results showed that,Castanopsiscarlesii(Hemsl)Hay was the dominant specie,its distribution of diameter class accorded with the regulation of normal nat-ural forest.Along with the increase in diameter class,its species and numbers of the arbor layer decreased.The domi-nant species distributed in the middle altitude class between 4~8m.Pielou evenness index,diversity index of com-munity and the ecological dominant index were 0.67,1.70 and 0.39,respectively,the most of natural secondary for-est communities were at the stable succession stage.
