Abstract: 1. The study of estimate primary production of Picea koraiensis forest communities was set up on the dune of Bai-yan-Ao-Bao district, ke Banner, Zhao-wu-Da League, Inner Mongolian.2. The estimated total biomass of picea koraiensis forest community is 109.31 ton/ha, total deadmass 25.40 ton/ha, net-production 1 ton/ha/year. Total aboreground biomass of spruce is 69.84 ton/ha, in which stem, branch, leab, cone and root is 45.14, 16.87, 7.83, 0.43 and 27.41 ton/ha respectively.The biomass ratio of spruce tree, spruce sapling, undergrowth, and living plant cover is 1:0.057:0.006:0.056.3. The suggestions:(1) Overmature spurce stand must be thinned by high thinning in order to raising biomass and productivity.(2) On acount of the xerophytic character of Picea koriensis, it may be used for afforestion in drought area of northern China as Pinus sylvestris and Pinus tabulaeformis.(3) As the spruce forest on the dune is very rare now, the protection of stand as nature reserve is necessary.
