摘  要：
以实测数据为基础,采用模型法分析了福建将乐林场粗叶榕、檵木、厚叶冬青、建润楠4种灌木生物量与地径(D)、株高(H)、冠幅(C)、植冠面积(A)、DH、D2 H的相关性。结果表明,以DH、D2 H为参数构建的w=a+b(DH)+c(DH)2+d(DH)3和W=a+b(D2 H)+c(D2 H)2+d(D2 H)3模型方程能更好地描述灌木的生物量与各形态因子的相关关系;同时,拟合灌木层混合生物量模型,其整株生物量模型为W总=35.4+4.19×10-2(DH)+2.03×10-3(DH)2+1.08×10-6(DH)3(R=0.921,SEE=0.921)。

摘  要：
Based on measured data,correlations between biomass and plant parameters of ground diameter(D),height(H),crown diameter(C),crown area(A),volume(V),ground diameter height product(DH)and ground diameter squared height product(D2 H)of 4bushes analyzed by establishing models,including Ficus hirta,Loropetalum chinense,Llex elmerrilliana,and Machilus oreophila occurring in Jiangle Forest Farm,Fujian.The correlation between the biomass of four shrubs was analyzed.The results exhibited that the relationship between shrubs biomass and various morphology factors could be properly described by the following equations:W =a+b(DH)+c(DH)2+d(DH)3,W =a+b(D2 H)+c(D2 H)2+d(D2 H)3.In addition,this equation:W =35.4+4.19×10-2(DH)+2.03×10-3(DH)2+1.08×10-6(DH)3(R=0.921,SEE=0.921),would be used to measure the plant biomass by fitting the whole shrub layer biomass model.
