【摘要】 通过退耕还林区撑绿杂交竹林分的调查,分析了撑绿杂交竹林分生物量变化规律,以及生物量和其它因子的相关性,并采用幂函数、指数函数、线形函数以及二次函数进行拟合,得出结论:撑绿杂交竹林分胸径、秆高、秆重、枝重、叶重、地上部分总重、枝盘数、竹秆节数等因子间相关关系密切。其中,竹高、胸径与节数、枝盘数、地上部分总重、秆重、枝重的相关达到极显著水平;胸径和秆重、地上部分生物量总重的拟合方程分别为:W=0.135 7 D1.738 9,R=0.976 6;W总=0.192 732 e1.757 9D,R=0.952 05。更多还原

【Abstract】 In this paper,the biomass structure of Bambusa pervariabilis×Dendrocalamopsis oldhami stand in districts of converting farmland to forest is analyzed.The results showed that there existed close interrelation between DBH,age of clums,clums weight,leaf weight,branch weight and the total weight of aboveground parts.The fitted equation of clums weight and DBH is W=(0.135 7 D^{1.738 9}),R=（0.976 6）,and that of the total weight and DBH is W_总=(0.192 732e^{1.757 9 D}),R=（0.952 05）.更多还原
