| Abstract: | Sample Tree Method(STM) was adopted to investigate the above-ground biomass.The correlations among biomass,the height & DBH of different parts of the individuals above-ground were analyzed.Biomass ratio of different parts above-ground shows that: the trunk,bark,leaves,the branches & branch bark is being 56.12%,7.8%,9.5% & 21.4%,5.2%,respectively.The order of the above-ground biomass of various organs is: the trunk> branch>leaf>bark>branch bark;quality of above-ground parts,trunk,bark,leaves,and sticks etc.w... |
