Community structure of large size soil acrofauna in different land use types

  • Published Date: July 14, 2013
  • Community structure of large size soil macrofauna were studied by quadrats statistical methods under four different land use types, including forest, forestmeadow, meadowsteppe and steppe in foreststeppe ecotone of Southeastern Inner Mongolia Plateau. There were 2 394 soil macrofauna individuals belonging to 22 orders, 8 classes and 3 phylums, and there were large changes in community composition and an obvious decreasing trend in the number of individuals. Besides, there were groups of large size soil macrofauna in the transition process from forest zone to steppe zone. It showed a significant differences(P<0.05)in the number of groups and densitygroup index(DG)of large size soil macrofaun between different land use types. The number of macrofauna individuals in forest zone were significantly higher than that in forestmeadow, meadowsteppe and steppe zone, and the diversity index (H) in forest zone was significantly greater than that in steppe zone. In contrast, there were no significant differences in evenness index (J) between four land use types. In short, the forest zone had the highest number of individuals, groups,H and DG values, followed by the forestmeadow zone, meadowsteppe zone and steppe zone.
