从泰山5种生境中获得土壤动物52类、4330只,分属于7门、11纲、25目、28亚目或科.优势类群2类、常见类群8类.探讨了5种生境土壤动物群落结构特征,并进行了多样性、均匀性及相似性分析.
In this paper,the community structure characteristics of Soil animal is apptoached in 5 types of habitat in Taishan Mountain. Soil animal of 52 sorts,individual number of which amounts of 4330, have been collected in Taishan Mountain. They belong to 7 phyla, 11 classes, 25 orders and 28 suborders or families. The superior sorts are Nematoda and Formicidae, the common sorts are Acarina, Enchytraede, Coleopterd, Collembola, Diptera, Chilopeda, Gastopoda, Homoplera, they accounts for 94. 27% of the total individuals and they constitute main parts of soil animal in Taishan Mountain. The composition and structure of soil aninmal in different community are closely correlated to their own ecological environmentul conditions. In Taishan Mountuin,the wide-ranging sorts are Mematoda, Acarina, Hyrmenoplera, Coleoptera, Chitopoda, Inplera, Homoptera, Symphyta,Oliqchaeta, opisthopea, the narrow-ranging sorts are Btattoplera, Psecdoscorptones, Turbeltarta, Hotura. In 5 types of habitat,the sorts number and individual number of soil animal show the following character: Grassland>Pinus tabulaeformis forest>Robinia Pseudoacacia forest>Platycladus orientalis forest>Pinus densiflora forest. The sort number and individual number of soil animal decrease gradually with increasing of the depth in soil and there are feature of soil animal congregating to surface horizon. It is analyed to diversity (H' )and evenness (J' )and dominance (C)and similarity of soil animal community in the paper. In 5 types of habitat,the diversity and evenness of soil animal show similar tendency to change, but they are opposite to dominance. All similarities of soil animal in five different communities are lower,they show that community comPOSitions of soil animal have more common characteristics in 5 types of habitat in Taishan Mountain.
