摘要: 对衡阳盆地紫色页岩土壤9种生境中的土壤动物进行了调查研究,共获得土壤动物3585只,隶属于4门8纲39目,其中线虫类、蜱螨类为优势类群,占总捕量的50.24%;常见类群12类,占总捕量的44.01%。从土壤动物水平分布上看,9种生境相似程度较大,其中尤以芦竹林和桃树林、阔叶林和桉树林、芦竹林和桉树林之间相似程度更突出。从土壤动物垂直分布上看,9种生境中只有桃树林、柑桔林垂直分布较为明显,而各种生境中土壤动物具有明显的表聚性。芦竹林、柑桔林、桉树林、菜地、阔叶林和桃树林6种生境土壤动物群落的多样性及均匀度呈基本一致的趋势,且各生境间差别不大.

Abstract: According to investigation and study on the soil animals of 9 habitats of the purple shale soil in the Hengyang basin,a total of 3585 soil animals belonging to 4 phylums,8 classes and 39 orders were obtained.Among them,the dominant groups werer nematoda and acarina,which amounted to 50.24% of total animals.Common groups were 12 sorts,amounting to 44.01% of total.The study on the horizontal distribution of soil animals showed that 9 kinds of habitat affinity level are higher.Among them,the affinity level is more significant between reed bamboo forest and peach forest,brmad leaved forest and eucalyptus forest,baraboo reed forest and eucalyptus forest .The study on the vertical distribution of soil animals showed that only peach forest and orange forest had clear layers among the 9 kinds of habitats,bamboo.Obvious surface aggregation appeared in all habitats.Divlayers ersity and evenness of soil animal community in reed, forest,orange forest,eucalyptus forest,vegetable plot,broad leaved forest and peach forest were consistent with each other.
