[Species diversity of ground-dwelling beetles on northern slope of Daba Mountain, China].
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.
