| 摘 要： | 选择贵州喀斯特高原三个典型地貌单元作为研究区,于2009-05对不同植被演替阶段的土壤动物群落进行研究.共获土壤动物3 992只,隶属于5门10纲26目,共31个类群,优势类群为弹尾目(Collembola)、甲螨亚目(Oribatida)、中气门亚目(Mesostigmata);常见类群为前气门亚目(Prostigmata)、膜翅目(Hymenoptera)、鞘翅目(Coleoptera)、半翅目(Hemiptera )、近孔寡毛目(Plesiopora)、双翅目(Diptera)、双尾目(Diplura).研究结果表明,随着喀斯特植被的不断退化,土壤动物数量不断减少,表现为林地＞灌丛＞草地＞石漠化地;类群数亦呈减少趋势.各演替阶段土壤动物表聚性明显,但人为干扰(如翻耕等)可导致土壤动物出现逆分布现象.土壤动物多样性分析表明,中小型土壤动物的多样性指数从林地到石漠化地逐渐减小.

| Abstract: | Soil fauna community was studied at different vegetation successions in the Karst Plateau of Guizhou Province in May,2009. A total of 3 992 individua1s of soil animals,belonging to 5 phyla,10 classes and 24 orders were collected and sorted into maero and meso/micro fauna. The dominant orders were Collembola,Oribatida,Mesostigmata,the frequent orders were Prostigmata,Hymenoptera,Coleoptera,Hemiptera,Plesiopora,Diptera and Diplura,the remnant orders were rare orders. The results show that with increasing degr... |
