摘要: 为探究竹林土壤动物群落结构，对位于浙江西部的竹林进行了调查研究。共记录到土壤动物24 328个，隶属5门11纲26目，优势类群为蜱螨目Acarina和弹尾目Collembola；物种多样性介于人工林动物群落和天然林动物群落之间。分层分析，多样性指数以土壤上层最高（1.382 6），下层最低（0.636 7）；均匀度指数以土壤中层最高（0.943 1），凋落物层最低（0.357 4）；丰富度指数以土壤上层最高（3.466 6），中层最低（1.021 7）；相似性指数土壤中层和土壤下层之间最高（0.800 0），凋落物层与土壤中下层之间最低。随着土壤动物的消费，土壤有机质从上到下依次降低，促使土壤动物随之发生演替，其物种多样性表现了逐渐降低的趋势。表4参25Abstract: The community structure of soil animals was studied in bamboo stands of Western Zhejiang with a stratified analysis. Results revealed 24 328 soil animals in total belonging to five phylum，11 classes，and 26 orders with the majority being Acarina and Collembola. The biodiversity level of bamboo stands was between plantations and natural forests. The stratified analysis showed that the highest diversity index value was in the upper stand layer （1.382 6），and the lowest was in the lower stand layer （0.636 7）；the highest evenness index value was in the middle stand layer （0.943 1），and the lowest value was at the litter layer （0.357 4）；and the highest richness index value was at the upper stand layer （3.466 6），and the lowest value was in the middle stand layer （1.021 7）. Meanwhile，the highest similarity index value was found between the lower and middle stand layers （0.800 0） with the lowest value between the litter layer and the middle-lower stand layer. With the consumption of soil animals，organic matter decreased from the upper layer to the lower layer as did biodiversity.［Ch，4 tab. 25 ref.］
