不同生境土壤跳虫及地表节肢动物群落结构和多样性特征

为探明天然次生林和人工油茶林土壤节肢动物多样性特征及其变化规律，基于Tullgren干漏斗法和罐诱法对八大公山亮叶水青冈林、枫香林、光皮桦林、栲树林和耒阳市南京乡半垦复油茶幼林、全垦复油茶幼林、全垦复油茶成林、未垦复油茶成林8种生境的土壤跳虫和地表节肢动物群落结构及多样性特征进行研究。Tullgren干漏斗法共分离出土壤跳虫1 830头，隶属4目10科19属；罐诱地表节肢动物12目24科34属1 136头。分析结果表明:天然次生林土壤跳虫的多样性显著高于人工油茶林，多样化的地表植被和凋落物有利于提高土壤跳虫的多样性，但对地表节肢动物没有显著影响；而油茶人工林不同垦复方式对跳虫群落和地表节肢动物结构及多样性均影响显著，适当垦复对于增加土壤动物的多样性具有积极作用。 

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 1830 soil collembolan which belonging to 4 orders, 10 families and 19 genera by Tullgren dry funnel method; and 1136 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.
