| Abstract: | By means of two kinds of mathematical analysis methods, i. e. stepwise linear regression, multiple linear regression combined with principal component analysis, seven mathematical equations of multiple regression for estimating the whole,above-ground and under-ground biomass of B.orientale and the above-ground biomass of W.japonica have been established. The measuring precision in quadrat samples all are up to 90 percent over.Diameter of coverage area, height, basal diameter, number of leaves, the length and width of leaf are included in the models. |
