To better understand the effect of forest succession on carbon storage of woody debris(WD),carbon stock and allocation of evergreen broadleaf forest,a major zonal forest in subtropical China was investigated.Three forest types were sampled,i.e.,pine(Pinus massoniana)forest(PF),pine and broadleaf mixed forest(MF)and evergreen broadleaf forest(BF).The amount of woody debris(WD)biomass was between 1.26-8.82 Mg/hm2,in the following order:PF<MF<BF,which showed a trend of increase gradually with the succession.Coarse woody debris(CWD)carbon content varies with tree species and its decomposition level,with the improvement of CWD decomposition level,its carbon content gradually decreases.The woody debris carbon storages of PF,MF,and BF were 0.62 Mg/hm2,1.75 Mg/hm2 and 3.78 Mg/hm2,respectively,corresponding to 0.73%,1.83% and 2.92% of the tree carbon storage.
