摘要
对茫荡山自然保护区的5个不同生境进行了昆虫多样性调查,并分别用物种丰富度S、个体数N、多样性指数H'、均匀度指数R和优势度指数D对不同的群落进行了统计分析。结果表明在不同生境中物种丰富度、个体数、多样性指数、均匀度指数和优势度指数皆不相同,其中常绿阔叶林内昆虫的丰富度、多样性指数和均匀度均为最高,针阔混交林次之,毛竹林为最低,但是毛竹林物种的优势度却是最高的。表明昆虫的多样性与其生境的植物种类、丰富程度密切相关。
The species composition and diversity of insects in five different habitats located in Mangdangshan natural reserve were surveyed, and the species richness, individual number, species diversity index, evenness index and dominant index were adopted to analyze the insect diversity difference in different communities. The results indicate that the species richness, individual number, species diversity index, evenness index and dominant index are distinctly different among different habitats, and the index such as richness, diversity and evenness in Evergreen Broad--Leaved Forest are the highest, Coniferous-- Broad Leaved Mixed Forest forest＇s index are higher than others, and bamboo forest＇s index are the lowest; But the bamboo forest＇s dominant index is the highest. This is mainly related to the biological characteristics of insects and directly affected by habitat＇s species and eveness.
