对南丰县建园20年以上橘园(样点A)、农田改建橘园(样点B)和荒山改建橘园(样点C)3个样点的土壤动物进行了实地调查。共捕获土壤动物1035头,隶属于4门9纲26目97科141种。定性、定量分析了3种类型南丰橘园的土壤动物群落结构、多样性及其水平分布、垂直分布。结果表明,三类群中,蜱螨目(Acaraina)、蜘蛛目(Araneae)、矛线目(Dorylaimida)是优势类群;多样性指数是:A>B>C;优势度C>B>A;相似性指数分析A与C之间的相似性最小。从土壤剖面分析来看,具有明显的表聚性,且表层>上层>中层>下层。
Field surveys were conducted on three soil animal species sampled from Nanfeng County for more than 20 years in Orangery (sample A), farmland conversion Orangery (sample B) and Barren Hill conversion Orangery (sample C). A total of 1035 soil animal were captured, belonging to 4 classes, 9 classes, 26 orders, 97 families and 141 species. Qualitative and quantitative analysis of soil fauna community structure, diversity, horizontal distribution and vertical distribution of the three types of Nanfeng orange orchard. Acaraina, Araneae and Dorylaimida were the dominant groups in the three groups. The diversity index was: A> B> C; dominance C> B> A; similar Sex index analysis A and C the similarity between the smallest. From the soil profile analysis point of view, with a clear surface aggregation, and surface> upper> middle> lower.
