Abstract
The spatial distribution patterns of biomass of 5 - years Pinus massoriana plantation were investigated in Jiangle County. The result indicated that the total biomass of P. masoniana was 35.512 t/hm2, the biomass of tree layer, undergrowth vegetation layer and litter layer were 28.608 t/hm2, 3. 861 t/hm2, 3.043 t/hm2, respectively, which accounted for 80.56％, 10.87％, 8.57％, respectively. The biomass distribution of each organ in tree layer followed the order of stems (40.90％) ＞ branches (255. 73 ％ ) ＞ roots (23.87 ％ ) ＞ leaves (9.50％ ). In terms of the biomass distribution patterns above ground in tree layer, the biomass distribution of branches and leaves of P. massoniana were mainly in 1 - 3 m section, whereas, the biomass distribution of stem were mainly in 0 - 2 m section.关键词
