Based on the data collected from a standard permanent plot of Pinus yunnanensis var.tenuifolia natural forest in Guangxi Yachang Forest Farm , the amount and distribution of biomass was studied by investigating and sample tree harvesting method , and the results showed that: 1) The total vegetation biomass of Pinus yunnanensis var.tenuifolia forest was 140.06 t/hm2 .2) The distribution law of biomass in each layer were arbor layer 127.75 t/hm2 (91.21 %), of which overstory trees contributed the large proportion (88.54%) and amounted to 124.01 t/hm2 , shrub layer 5.21 t/hm2 (3.72%), herb layer 2.56 t/hm2 (1.83%), litter 1ayer 4.54 t/hm2 (3.24%). 3) In the overstory layer , the biomass was allocated as 57.61 t/hm2 (46.46%) for trunk, 9.97 t/hm2 (8.04%) for bark, 23.25 t/hm2 (18.75 %) for branch, 9.26 t/hm2 (7.47 %) for leaf, and 23.92 t/hm2 (19.18 %) for root .
