Abstract:In Wuchang Fenghuangshan Forest Farm on the west slope of Zhangguangcai Mountain, we selected Larch(Larix olgensis L.), Larch and broad-leaved mixed forest(H), and secondary broad-leaved natural forest(C) in different origins(artificial regeneration, artificial-natural regeneration, and natural regeneration) to study the carbon storage of tree layer, shrub and grass layer, the litter layer, soil layer and the total carbon storage of all three types of forest stands, explore the effects of different ways of regeneration on forest carbon storage, and determine the way of forest regeneration with high carbon sequestration capacity. Artificial-natural mixed stand could increase the carbon storage of the shrub and grass layer(P<0.05). L showed the highest carbon storage of undecomposed litter layer, semi-decomposed litter layer and the highest total carbon storage of litter, and its carbon storage in the semi-decomposed litter layer and the total carbon storage of litter were significantly different in the three forest types(P<0.05). The total soil carbon storage and the total carbon storage of the forest ecological system were higher in H than that in the other two forest types, but the difference was not significant(P>0.05). The artificial-natural regeneration was conductive to increasing the carbon sink capacity of vegetation and soil, and Larch artificial regeneration had high carbon storage of litter.
