| Abstract: | After the natural regeneration measures on the cut-over land of the evergreen broadleaved forest,the total biomass of 13-year-old Castanopsis fissa stand reaches 113.758t/hm 2,among which the green biomass is 108.382t/hm 2 and the existing litter is 5.376t/hm 2.The bole biomass accounts for 58.78% of the above-ground biomass.Several regression models are applied to set up the regression equations of C.fissa different organs'biomass distribution and dbh.Through the check the predictive effects of the quadratic equation and linear equation are better,which may be used for the productive practice. |
