ABSTRACT

With the degraded red soils of eroded bare land (I), xeric mesophilous herbosa (II), sparse coniferous woodland (III), coniferous woodland (IV), coniferous-broadleaf mixed woodland (V), and evergreen broadleaf forest (CK) as test objects, this paper studied the effects of vegetation restoration on the collembolan communities in degraded red soil. A total of 23 genera belonging to seven families and two suborders were observed, including dominant taxa such as Folsomia, Folsomina, and Sminthurinus. The characteristics of soil collembolan community were analyzed by using the indices such as individual density, taxa number, diversity, abundance, and evenness. The test indices were the lowest in I, and the highest in CK. The soil collembolan communities in II, III, IV and V were restored to some extent, but the restoration was still at early stage, with less difference observed. Bray-Curtis index had the largest difference (0.99) between eroded bare land and CK, larger differences between the four restored plantations and CK, and less difference between four restored plantations.
