【摘要】 2013年7月分别对位于喀斯特地区的广西壮族自治区河池市宜州区境内的葡萄、板栗、玉米、柑橘、柚子、桑树、水稻、香蕉、松树、甘蔗10种农作物下20个样地的土壤动物多样性进行调查。结果表明:20个样地共获土壤动物2 861只,隶属3门8纲14目,共18个类群,其中优势类群为弹尾目和蜱螨目,占比为89.97%;常见类群为膜翅目、线蚓科、单向蚓目、鞘翅目、双翅目5类,占比为8.52%。对喀斯特地貌不同农作物下土壤动物群落多样性研究表明,在垂直分布上,土壤动物类群数和个体数均呈现出表聚现象,在水平分布上的差异与人类的干扰程度息息相关。更多还原

【Abstract】 In July 2013,soil fauna in Karst area was investigated with emphasis on species richness and abundance in relation to crop land with 10 crop types such as grape,Chinese chestnut,orange,grapefruit,maize,rice,bananas,pine and sugar cane. Result shows that the captured 2 861 soil animals belonging to18 groups,14 orders,8 classes,3 phyla. Two dominant groups,Collembola and Acarina,accounted for 89. 97% of the soil fauna individuals. Five common groups,Hymenoptera,Enchytraediae,Haplotaxidae,Coleoptera and Diptera,accounted for 8. 52%. According to the reseach about the diversity of soil fauna under different crops in Karst area,the vertical distribution of soil fauna groups and individuals in the soil profiles shows a surface accumulation,but the difference of horizontal distribution of soil fauna is closely related to human activities.更多还原
