| 摘 要： | 为了解喀斯特高原盆地土壤动物群落结构,于2008年2月对清镇簸箩小流域4种不同等级石漠化即无石漠化、潜在石漠化、轻度石漠化和中度石漠化样地的土壤动物群落进行了调查。结果显示,共获土壤动物688头,隶属2门7纲14目,其中优势类群是蜱螨目、弹尾目和膜翅目。无石漠化样地土壤动物的种类最多、密度最高、多样性最丰富。轻度石漠化和中度石漠化样地土壤动物群落具有较大的相似性。土壤动物的个体数与石漠化程度、土壤有机质含量、含水量和土壤孔隙度呈显著的正相关关系,与pH呈显著的负相关关系。随着石漠化程度的加剧,土壤动物群落结构受到很大影响。

| Abstract: | The community of soil fauna of sample plots with non-rocky desertification,potential rocky desertification,mild rocky desertification and moderate rocky desertification was surveyed in Boluo Karst minor watershed to know the community structure of soil fauna in Karst plateau basin.The results showed that 688 soil animals belonging to 14 orders,7 classes and 2 phylums were collected and the dominant groups were Acarina,Collembola and Hymenoptera,the species,density and diversity of soil fauna in the sample p... |
