Abstract: Studies were made of the distribution of main nutrient elements and biomass of the young Eucalyptus grandis plantation in Shuangliu county in Sichuan province. The results showed that the whole plant fresh weight of the 4-year-old Eucalyptus grandis standard wood was 311.24 kg,while the 5-year-old was 484.02 kg. The ranked order of the biomass distribution of two kinds of Eucalyptus grandis plantation was trunk > bark or big branch > branchlet > leaf > fruit. The distribution regularity of nutrient element content in different organs of the two kinds of Eucalyptus grandis plantations. And its ranked order was leaf > fruit > big branch or branchlet > bark > tree trunk. From the perspective of nutrients and organic matter distribution in the trunk,N,P,K,Mg content presented basically increasing with the trunk height. Organic matter content was the highest in central trunk,while organic matter content of the trunk decreased when the tree height increased. The Ca content in stem base was the highest and the lowest in central trunk. From the aspects of Eucalyptus grandis plantation nutrient accumulation and distribution,the nutrient elemnet accumulation of two kinds of Eucalyptus grandis plantation was proved to be consistent. N accumulation was the highest in the two kinds of plantations,followed by the Ca,K,Mg,P. N content accumulation of four years old Eucalyptus grandis plantation was 637.32 kg·hm^-2,while the five years old Eucalyptus grandis plantation was 1 134.17 kg·hm^-2.
