Relationships between carbon density of dead organic matter, and biotic and climatic factors. The y axis is carbon density (Mg C ha−1) of a–f fine woody debris (FWD), g–l coarse woody debris (CWD), and m–r litter. All plots showed the linear relationships between a, g and m above ground biomass carbon density, b, h and n forest age, c, i and o net primary production (NPP), d, j and p mean annual temperature (MAT), and e, k and q precipitation (MAP), and (f, l and r) soil carbon density and carbon density of each component of dead organic matter. There were no significant linear relationships between carbon density of litter and forest age, and between carbon density of FWD and carbon density of soil
