小秦岭自然保护区森林群落昆虫多样性研究

Study on Insect Diversity of Forest Community in Xiaoqinling Nature Reserve

在河南省小秦岭自然保护区设立72块标准样地,对7种森林群落中的昆虫多样性进行了调查和分析,并比较了不同森林类型中昆虫群落的相似性,为该地区生态保护和资源利用提供昆虫方面的基础资料。结果表明:小秦岭自然保护区主要有昆虫14目79科517种,优势类群为鞘翅目、鳞翅目、半翅目、膜翅目和直翅目等;阔叶混交林和针阔混交林中的昆虫多样性较高,秦岭冷杉林、油松林、华山松林和灌丛矮曲林中的昆虫多样性处于中等水平,而竹林中的昆虫多样性最低;总体上针阔混交林昆虫群落组成与其他森林类型相似性较高,而竹林与其他各森林类型的相似性较低。

According to the investigation and analysis on insect diversity of 72 vegetation plots among seven kinds of forest communities in Xiaoqinling natural reserve of Henan province,similarity of insect community was compared in different forest communities. The result indicated that a total of 517 species belonging to 79 families in 14 orders were identified,of which Coleoptera,Lepidoptera,Heteroptera,Hymenoptera and Orthoptera were the major orders. The highest diversity of insect community was in broad leaved mixed forest and mixed coniferous broad leaved forest,moderate diversity was in Abies chensiensis forest,Pinus tabuliformis forest and Pinus armandii forest,and the lowest was in bamboo forest. Higher similarity of insect community was observed between mixed coniferous broad leaved forest and the others,and which was lower between bamboo forest and the others.
