A study on biomass of 50-year-old Keteleeria fortunei plantation in Yongchun, Fujian province was carried out. The results showed that on aboveground part of K. fortunei, the average biomass of the trunk was the maximum of 218.29 kg per plant, the average biomass of the leaf was the minimum of 15.44 kg per plant. In underground part of K. fortunei, the biomass of the root whose diameter was greater than 15.0 cm was the maximum of 52.84 kg per plant, and the biomass of the root whose diameter was less than 1.0 cm was the minimum of 0.84 kg per plant. The biomass distribution of different organs followed an order as trunk > root > bark > branch > leaf. The biomass of arbor layer was 699.57 t穐m-2, the net productivity of forest stand was 13.99 t穐m-2穉-1, the biomass of undergrowth vegetation layer was 11.22 t穐m-2, the biomass of litter layer was 5.35 t穐m-2.
