Abstract

In this study, we selected the 2-year, 5-year, 8-year, 34-year and 57-year artificial sand-fixing vegetation area in the southeastern Tengger Desert as study sites, and the mobile sand land was used as the control. The community composition and the diversity characteristics of ground-active arthropods in the revegetated areas of different years were investigated by using pitfall trapping method. Combined with environmental factors, we clarified the response of ground-active arthropod diversity to vegetation succession in the revegetated areas. The results showed that: (1) a total of 15685 ground-active arthropods were obtained in this study, belonging to 15 orders, 40 families and 44 groups. Alongside the succession of the revegetated areas, there was no significant change of the number of dominant groups, whereas the number of common groups and rare groups increased by 0.5-2.5, 0.25-2.75, respectively, in comparison to the mobile sand land. And the number of the predatory, herbivorous and omnivorous groups increased by 0.5-3.0, 0.2-4.2 and 0.3-1.67, respectively. (2) Alongside the succession of revegetated areas, the total abundance of ground-active arthropods in 8-year and 57-year revegetated area was significantly higher than that in mobile sand land (P<0.05), and increased by 3.85 and 3.03, respectively. There were significantly higher number of groups and diversity index of ground-active arthropods in 57-year and 34-year revegetated area than that in other sites, with the peak in 57-year revegetated area (P<0.05). The number of groups of ground-active arthropods was found to be significantly higher in 57-year revegetated area compared with 34-year revegetated area (P<0.05). (3) Herb density, soil organic carbon and shrub height were the main environmental factors driving the community composition and diversity of ground-active arthropods in the revegetated areas. Their contribution rate was 48.1%, 25.2% and 9.1%, respectively. Herb density and soil organic carbon had significantly positive correlation with the total abundance, the number of groups and the diversity index of ground-active arthropods (P<0.05). Shrub height showed significantly positive correlation with the total abundance, and significantly negative correlation with the number of groups and the diversity index of ground-active arthropods (P<0.05). In conclusion, there were different adaptabilities of ground-active arthropods to environmental conditions in the revegetated areas. It suggested that the revegetated plantations could improve the diversity of ground-active arthropods, and 34 years of revegetated plantations was the key time node for biodiversity conservation and desertification control in desertification region.
