Abstract: The measurement of the biomass and net productivity of spruce (Picea schrenkiana var. tianshanica) forest in Mulei County of Xinjiang showed that the total biomass was 216.170t·hm-2, and the net productivity was 12.634t·hm-2·yr-1. The biomass percentages of stem, twig, needle, fruit and root were 48.68%, 17.77%, 9.81%, 0.03% and 18.60%, respectively and the net production percentages of them were 31.49%, 1.20%, 12.70%, 0.46% and 26.87 %, respectively.
