摘　　要：在神农架自然保护区7种生境中土壤表面共获取土壤动物2 467只,分别隶属于21个类群,类数组成以高草最丰富,草地最贫乏。其中,甲螨类和革螨类为优势类群,分别占土壤动物全捕获量的64.17%、16.70%,其他种类为常见类群和稀有类群。两两相比,7种生境相似性指数较高。在7种生境中,杉树林、竹林和原始林生境中多样性指数较高,表明生境条件较优越。There were 2 467 soil animals＇ specimens collected in soil layer of seven habitats in Shennongjia.They belonged to 21 species.The meadow had the most abundant composition and the grassland had the poorest.The dominant species were beetle mites and gamasid mite,and they accounted for 64.17% and 16.70% of the total animals respectively.Others were common or rare species.According to the analysis,the index was higher between the two habitats. Diversity index was higher in cedar forest,bamboo forest and virgin forest,which showed that they had better habitat environment than those of the other habitats.
