Litterfall, which is the basic carrier of nutrients, is a major contributor to material recycling and energy transformation in a forest ecosystem. However, only a few studies focus on the spatiotemporal distribution characteristics of leaf-litter nutrients in a subtropical forest community with high diversity. Therefore, in this study, we estimated the composition of leaf-litter nutrients, including total carbon, nitrogen, and phosphorus contents, by collecting the leaf-litter during the year from evergreen species in spring and summer litter peak and from deciduous species in autumn litter peak; we utilized a 20 hm² dynamic plot of subtropical evergreen broad-leaved forest in Tiantong with tough topography. Our results indicated that, in the temporal scale, the C concentration in the leaf-litter was lower in the autumn peak litter of deciduous species than that in the spring and summer peak litter of evergreen species, while the N and P concentrations were higher in autumn peak of deciduous species than that in the spring and summer peak litter of evergreen species. Further, in the spatial scale, the C concentration in the leaf-litter was lower in the valley than that in the ridge, while the N and P concentrations were lowest in the ridge among habitats in the autumn peak litter of deciduous species. These results indicated that the species composition and lifeform of communities determine the spatiotemporal distribution of the leaf-litter nutrients in a subtropical evergreen broad-leaved forest.
