摘    要:1993到1995年,用落叶袋法研究跳虫群落在青冈Cyclobalanopsis glauca、马尾松Pinus massoniana和麻栎Quercus acutissima 3种乔木落叶分解过程中的演替变化。青冈落叶分解经淋洗、养分固定和养分活化3个阶段,马尾松和麻栎没有出现阶段性变化。青冈落叶中跳虫个体数和多样性指数均高于马尾松和麻栎落叶中的相应值。跳虫在落叶分解过程中的集聚型分为3组:A组为落叶分解前期集聚的种类,B组为后期的种类,C组为中期或全过程的种类。3种乔木在A组中共有的种类为鳞Tomocerus sp.、等节Isotoma sp. 和杭州刺齿Homidia hangzhouensis;B组共有种类为八眼符Folsomia octoculata、拟裸长角Pseudosinella sp. 和类符Folsomina onychiurina;C组没有共有种类。

关 键 词:土壤跳虫  群落结构  演替  乔木  落叶分解

Abstract:Changes in collembolan community structure were investigated respectively in the litter under the three species of trees,\%Cyclobalanopsis glauca (Cg), Pinus massoniana (Pm) and \%Quercus acutissima (Qa) in the same forest ecosystem during decomposition of the litter from April 1993 to April 1995.The decomposition process of Cg litter consisted of three phases:leaching phase,lasting from start of the experiment to the 7th month;immobilization phase,from 7th to 16th month;and mobilization phase,from 16th to 24th month.On the other hand,there were no such distinguishable phases during the observing period in both Pm and Qa litter.The greatest collembolan abundance and diversity index occurred in Cg litter.According to their occurring patterns during the litter decomposition,the collembolan species could be recognized as following three categories:the earlier colonizers (A),the later ones (B) and the long\|term colonizers or those appeared only in the middle stage (C).\%Tomocerus\% sp.,\%Isotoma\% sp. and \%Homidia hangzhouensis\% in the category A,and \%Folsomia octoculata,Pseudosinella\% sp.and \%Folsomina onychiurina\% in these litter category were shared by the 3 types of litter respectively.There were no common species in the category C.
Keywords:Collembola  community structure  succession  arbore  litter decomposition
