20 tree plots, 60 shrub plots, 100 grass plots and 100 litter plots were established in Central Tianshan Mountain to study the biomass and carbon storage of P. schrenkiana var. tianshanica - A. millefolium community, P. schrenkiana var. tianshanica - S. pohuashanensis community and P. schrenkiana var. tianshanica - S. pseudosabina community. Results showed that: (1) Biomass of above ground and below ground of P. schrenkiana var. tianshanica made up about 85.27 % and 14.73 % of the totals, respectively. Biomass of stems, branches and leaves made up 52.99 %, 29.16 % and 13.55 % of the totals, respectively. (2) Total biomass of P. schrenkiana var. tianshanica - A. millefolium, P. schrenkiana var. tianshanica - S. pohuashanensis and P. schrenkiana var. tianshanica - S. pseudosabina community was 259.94 t·hm-2, 210.97 t·hm-2 and 91.39 t·hm-2, respectively. Biomass of tree layers of three communities above mentioned was 248.1 t·hm-2, 194.3 t·hm-2 and 72.1 t·hm-2, respectively. Biomass of shrub layers of three communities above mentioned was 0.2 t·hm-2, 9.9 t·hm-2 and 17.1 t·hm-2, respectively. Biomass of herbage layers was 0.18 t·hm-2, 0.29 t·hm-2 and 0.28 t·hm-2, respectively. Biomass of litter layers was 11.48 t·hm-2, 6.54 t·hm-2 and 1.92 t·hm-2, respectively. (3) Carbon storage of three communities above mentioned was 130.87 t·hm-2, 106.00 t·hm-2 and 45.83 t·hm-2, respectively. Carbon storage of tree layers of three communities above mentioned was 124.03 t·hm-2, 97.14 t·hm-2 and 36.03 t·hm-2, respectively. Carbon storage of shrub layers was 0.11 t·hm-2, 4.94 - - t·hm-2 and 8.56 t·hm-2. Carbon storage of herbage layers was 0.08 t·hm-2, 0.13 t·hm-2 and 0.13 t·hm-2, respectively. Carbon storage of litter layers was 6.66 t·hm-2, 3.79 t·hm-2 and 1.11 t·hm-2, respectively.
