Abstract：

  [Objectives]  With the continuous increase of new afforestation of Camellia oleifera, the occurrence of pest is becoming more and more serious, C. oleifera seed oil safety is threatened. In order to explore the way of effectively controlling the C. oleifera forest pest, protect the diversity of decomposition such as soil arthropod. [Methods]  Based on Tullgren dried funnel and pitfall traps method, systematically studied soil collembolan and other arthropod diversity characteristics in C. oleifera forest of four different reclamation ways. 100 trap tanks were set in 20 quadrates, 20 soil samples and 15 litters of 4 different reclamation ways in C. oleifera were sampled. [Results]  315 springtails belonging to 6 families and 8 genera were detached and identified; 295 soil other arthropod belonging to 11 families were identified. Variance analysis results showed that, the biological diversity index of the grown C. oleifera forest are higher than the young, rich variety of ground cover is beneficial to improving the soil arthropods diversity, human disturbance such as reclamation and fertilization can significantly reduce the diversity of soil springtails, but it is helpful to increase tank trapped arthropods diversity; Water is the key factor of soil arthropods survival, and has a significant role in promoting the diversity of woodland springtails and tank trapped soil arthropods. [Conclusion]  It can provide a scientific basis for reasonably reclaimming C. oleifera forest, promoting the decomposition functional of soil Collembola and arthropod by ascertaining the diversity characteristics soil Collembola and arthropod in different reclamation type of C. oleifera oleifera forest.
