| Abstract: |
| Four plots of representing succession in grassland, bush, shrubbery and original forest in Maolan Nature Reserve were selected, via the space-time replacement method, to study the impact on soil micro-arthropods of the restoration of a degraded Karst ecosystem. The characteristics of soil micro-arthropod communities and their relationship with the physicochemical factor of soil were analyzed during the process. The results recognized the presence of total of 121 soil micro-arthropods, belonging to two classes, three orders, and nine families, and that the community of soil micro-arthropods was rich, among which cryplosligmatic and predatory mites were the dominant community at different stages. Pearson analysis showed that ammonium nitrogen and easily oxidizable carbon had significant effects on the structure and diversity of soils micro-arthropod communities in terms of their nutrient function(except for the Pielou index). The restoration of degraded Karst ecosystem has a very significant impact on the diversity, richness and uniformity of soil micro-arthropods, and plays a positive role in forming soil micro-arthropod communities. |
