摘    要:1993年5月-1995年4月,采用落叶袋法研究了中亚热带青冈(Cyclobalanopsisglauca)林土壤动物在落叶分离过程中的演替,变化,用多样性指数,演替指数,相似系数分析土壤动物群落结构的季节变化和在落叶分解过程中的演替,分解出现的类群,密度最高的为蜱螨目(Acarina)其次为弹尾目(Collembola),二者个体数之和占总数的92.7%,其他依次为:双翅目(Diptera)膜翅

关 键 词:土壤动物  演替  落叶分解  群落结构  青冈林

Abstract:Changes in soil animal communities during leaf litter decomposition were studied with litter bag method over a two year period (from May 1993 to April 1995) in Cyclobalanopsis glauca forest.The community organization was compared among different stages of the leaf litter decomposition. For the soil animals, the su ccessional changes in the community structure were expressed by the diversity in dex,succession index and similarity index. Soil animals showed changes in the c ommunity throughout the period. In the study, the most dominant taxa in density was Acarina,and the second was Collembola,both accounting for 92 7% of total individuals.Diptera,Hymenopte ra,Araneae,Homoptera,Pauropoda,Protura and Lepidoptera took less place.The c olonization of the taxa more correlating with the mass loss of the leaf litter w ere Araneae,Collembola,Diptera,Oribatida and Acarina in order.Colembola,Dipt era,Homopter,Araneae and Lepidoptera were earlier colonizers and colonized for 6 to 8 months during the 2 year decomposition period,while Acarina and Oribati da occurred in the whole decomposition and colonized for 8 to 12 months. The succession of the communities was related to the changes in food resource du ring decomposition.Araneae,Collembola and Diptera showed significant positive c orrelation with the mass loss,Acarina and Oribatida normal positive correlation ,Protura and Pauropoda negative correlation,and Homoptera,Lepidoptera and Hym enoptera litter correlation. The feeding of the animals were compared in relation to the changes of the food resource.
Keywords:Soil animals  Succession  Decomposition  Community  Forests
