Abstract:Based on the permanent plot and investigation,the biomass,carbon storage and its allocation of Phyllostachy edulis forest and evergreen broad-leaved forest were studied.The results showed that the mean carbon concentrations among tree species were significantly different.The average carbon concentration in organs of Ph.edulis changed in the order of culm(47.53%)>branch(46.49%)>rhizome(46.10%)>root(45.30%)>leaf(42.22%),in the order of trunk(45.53%)>leaf(44.96%)>branch(43.63%)>root(43.09%)for Castanopsis fargesii,and 40.21%-49.54% for different organs of other woody species.The carbon concentration of soil of 2 forests are 4.15%-0.58% and 3.62%-0.43% from 0 to 100 cm depth respectively,with higher carbon concentration and storage in the layer of 0-20 cm than in the other layer.The total carbon storage of Ph.edulis forest and broad-leaved forest were 226.75 tC·hm-2 and 267.94 tC·hm-2 respectively.The spatial distribution pattern of carbon storage was basically consistent in the order of soil layer>trees layer>shrub and herb and litter layer.The carbon storage and its allocation among their organs in tree layer were found to be highly correlated with their biomass.Annual carbon fixation of plant layers in Ph.edulis forest was 4.76 tC·hm-2·a-1,amounted to 17.45 tCO2·hm-2·a-1,higher than that of evergreen broad-leaved forest of 15.22 tCO2·hm-2·a-1.
