* Significance level at P < 0.01; ** Significance level at P < 0.001.

† Collecting from W. H. Li's field data in the book of Tibetan Forests (Li 1985). Live stem biomass was estimated by dual volume equations and unit weight; live biomass of branch and leaves were estimated through regressions of their weights to the base diameter of sampled branches and the measurements of base diameter of all branches for each of sample trees in stem analysis research.

‡ Dr. H. Jiang had modified the regressions in his published paper in 1986. Here were the modified equations.
