Abstract:Based on the biomass surveys of Pleioblastus amarus in Zhongtai Township of Yuhang District,Hangzhou,the matrix of correlation efficient among various organs of Pl.amarus were established.The best mathematical models of various bamboo organs and the diameter at breast heigh,height or lowest branch height were constructed through regression analysis.The models were as follows:m_(stem)=13.439 5D~(2.004 8)H~(0.422 5);m_(branch)=2 956.359 8D~(1.992 9)H~(-0.641 0);m_(leaf)=43.746 7-30.541 2D 53.759 7D~2;m_(root)=270.956 0D~(2.357 9)H~(-0.399 5);m_(subterranean stem)=512.436 1-175.936 0D 2.907 8H_0;m_(aboveground)=432.446 8-479.307 5D 422.828 5D~2;m_(underground)=396.622 3-53.286 9D 2.877 5 H_0;m_(total)=191.038 0D~(1.198 6)H_0~(0.296 2)?Using these models,the biomass of various organs of ramet and forest of Pl.*"amarus were calculated respectively.This result had reference to the evaluation of productive potentialities and guidance of production of Pl.*"amarus.
Keywords:Pleioblastus amarus  biomass  regression analysis  mathematical model
