By using pitfall trapping, the species composition and quantitative distribution of ground-dwelling beetles in man-made plantations in forest farm (MPFF), secondary natural forests in farmland (SFF), and man-made plantations in farmland (MPF) on northern slope of Daba Mountain were analyzed, and detrended correspondence analysis and cluster analysis were adopted to study the similarity of the species composition and quantitative distribution of the beetles among the three forest types. 1094 individuals of ground-dwelling beetles were captured in August 9-13th, 2002. Of these beetles, Staphylinidae and Chrysomelidae accounted for 40.59% and 33.18% of the total, respectively, and Carabidae, Leiodidae, Scarabaeidae, Curculionidae, Ptiliidae, and Pselaphidae each took more than 1% of the total. These eight families were considered as the common-occurring groups in the study area. The individuals of ground-dwelling beetles decreased from MPFF to SFF to MPF, and the family richness was obviously lower in MPF than in MPFF and SFF. The family composition and abundance of the beetles were significantly different between MPFF and SFF, but partial similarity was observed between MPF and other two forest types.
通过陷阱诱捕法，对大巴山北坡林场人工林（MPFF）、农田次生天然林（SFF）和农田人工林（MPF）中地面甲虫的种类组成和数量分布进行了分析，并采用除趋势对应分析和聚类分析研究了三种林型中甲虫种类组成和数量分布的相似性。2002年8月9日至13日共捕获地面甲虫1094只。其中，隐翅虫科和叶甲科分别占总数的40.59%和33.18%，步甲科、阎甲科、金龟科、象甲科、扁甲科和伪蕈甲科各占总数的1%以上。这八个科被视为研究区域内的常见类群。地面甲虫个体数量从MPFF到SFF再到MPF逐渐减少，MPF中的科丰富度明显低于MPFF和SFF。MPFF和SFF之间甲虫的科组成和丰度存在显著差异，但MPF与其他两种林型之间存在部分相似性。
