Abstract
Sample-plots were set in 35 years old standing forest of Pinus tabulaeformis Carr.in TaiHang forest region, in Shanxi province.Sample tree biomass was investigated according to different diameter grade.Results showod that the distribution of biomass a mong different organs is contributed mostly to the trunk,which was about 44\^08%～64\^95%. The branch,the leaf and the root were 18\^31%～28\^73%,9\^2%～12\^94% and \{10\^85%～16\^38%\} respectively.Through the statistics analysis,the correlation between tree biomass and the diameter grade was obviously.Close relationship was between the biomass of various organs , D 2 1.3 H and the patterns of biomass change had been set.
