| 摘 要： | 采用模型法研究了雾灵山自然保护区锦带花、木本香薷、小花溲疏、山楂叶悬钩子4种灌木生物量与地径(D)、株高(H)、冠幅(C)、植冠面积(A)、植株体积(V)、基径与株高乘积(DH)、基径平方与株高乘积(D2H)的相关关系。通过回归分析拟合了各灌木种器官生物量与总生物量模型,结果表明:W=a+b(D2H)+c(D2H)2、W=a+b(D2H)+c(D2H)2+d(D2H)3、W=aVb、W=a+bV+cV2+dV3、W=a+bV+cV2能较好地描述灌木种叶生物量、枝生物量、根生物量及总生物量与各形态因子的相关关系。

| Abstract: | Model method was applied to study Weigela florida,Elshollzia stauntoni,Deutzia parviflora and Rubus crataegifolius in Wuling Mountain.The relationship between the four shrubs biomass and ground diameter(D),height(H),crown diameter(C) crown area(A),volume(V),ground diameter height product(DH) and ground diameter squared height product(D2H) were discussed.Regression analysis was emploied to analysis the shrubs organs biomass model and total biomass model.The results indicated that the relationship between shrubs morphology factors and leaf biomass,branch biomass,root biomass and total biomass could be well described by the following equations : W=a+b(D2H)+c(D2H)2,W=a+b(D2H)+c(D2H)2+d(D2H)3,W=aVb,W=a+bV+cV2+dV3,W=a+bV+cV2. |
