Abstract:Biomass and nutrient element accumulation of Sabina przewalskii forest community of different types were measured in the Qilian Mountains. The result showed that the average biomass of S.przewalskii was 231.20t/hm 2, of which arbor layer made up 98.34%,brushwook layer 1.60%,herb layer 0.06%; the total of the nutrient element accumulation was 3633.81kg/hm 2, in which the proportion of Ca, N and K was the biggest,which were 54.27%, 19.55% and 11.05% respectively, that of Zn was the smallest, it was only 0.03%.
Keywords:Sabina przewalskii  community  biomass  Nutrient element accumulation
