【 摘 要 】

The composition of natural forest was relatively complex. The research of its biomass allocation could lay a foundation for the carbon storage study. The biomass allocation of pine-oak mixed forest in Xiaolong mountain was analyzed through plot survey. The average individual biomass of Quercus aliena var. acuteserrata, Pinus armandi, Pinus tabulaeformis, and broad-leaved tree species was 67.86±21.21kg, 104.58±61.02kg, 32.07± 9.37kg, 30.05± 9.19kg and the average individual volume was 0.08±0.02 m3, 0.11±0.06 m3, 0.05±0.02 m3, 0.03±0.01 m3. The biomass of tree layer for each tree species was 56.47 ±25.80 t/hm2, 18.88± 15.99 t/hm2, 17.26± 11.66 t/hm2, 17.99± 16.38 t/hm2, and the average volume were 66.96±32.60 m3/hm2, 19.47±16.44 m3/hm2, 28.82±20.19 m3/hm2, 22.82±15.61 m3/hm2. The biomass among different organs in the same tree species and among different tree species in the same organ were significant differences. Taking the organ carbon content as 0.5, the carbon storage of each tree species was 28.24±12.9t/hm2, 9.44±7.99t/hm2, 8.63±5.83t/hm2, 8.99±8.19t/hm2, respectively.
