共青林场节肢动物群落分析研究

Study on The Arthropod Community in Gingqing Forestry Center

该文对共青林场3个分场的节肢动物群落总数、种群分布、群落多样性以及相似性进行了分析研究。结果表明:鳞翅目和鞘翅目是共青林场的优势物种,节肢动物个体总数和Simpson指数均为河南村分场>李遂分场>郝家疃分场,郝家疃分场和河南村分场节肢动物群落物种Jaccard相似系数最低(J=0.0978),郝家疃分场和李遂分场的节肢动物群落物种Jaccard相似系数较低(J=0.1163),李遂分场和河南村分场的节肢动物群落物种Jaccard相似系数较高(J=0.5057),说明郝家疃分场和李遂分场、河南村分场的节肢动物群落物种极不相似,而李遂分场和河南村分场的节肢动物群落物种为中等相似。

In this research,the number,population distribution,diversity and similarity of arthropod community were investigated,as the conclusion showed as follows： Lepidoptera and Coleoptera were dominant species in Gongqing forestry center,both of the total individual number and the simpson index were Henan cun sub-forestryLisui sub-forestryHaojia tuan subforestry. Jaccard similar coefficient were low（J=0.0978,0.1163）in Haojia tuan sub-forestry and Henan cun sub-forestry,Haojia tuan sub-forestry and Lisui sub-forestry respectively,which showed that arthropod community species in significant difference. Jaccard similar coefficient was high（J =0.5057）in Henan cun sub-forestry and Lisui sub-forestry, which showed that arthropod community species in medium similarity.
