Structure and diversity of soil collembolan and aboveground arthropod communities under different habitats

In order to explore the impact of vegetation types of natural secondary forest and the reclamation types of artificial Camellia oleifera forest on the soil fauna biodiversity, we investigated the community structure and diversity characteristics of soil collembolan and other arthropods in 4 types of natural secondary forest in Badagong Mountains National Nature Reserve and 4 types of artificial Camellia oleifera forest in Nanjing Township, Leiyang City, Hunan Province of southern China based on Tullgren dry funnel method and pitfall trap method. We captured 1 830 soil collembolan which belonging to 4 orders, 10 families and 19 genera by Tullgren dry funnel method; and 1 136 other soil arthropods which belonging to 12 orders, 24 families and 34 genera by pitfall trap method. The analysis results indicated that: 1)the soil collembolan biological diversity of natural secondary forest was significantly higher than artificial Camellia oleifera forest. 2) The multiplex component of surface vegetation and litter were beneficial to improving the diversity of soil collembolan, but no obvious impact on the surface arthropods.3) Proper reclaiming type was helpful to increase the biological diversity of soil fauna by promoting both the soil collembolan and surface soil arthropod community diversity.
