摘要:
 旨在研究福建省将乐县国有林场地区不同生长势杉木成熟林胸径-树高状况,以福建将乐国有林场不同生长势杉木成熟林为研究对象,采用树干解析的方法获取杉木优势木、中庸木和被压木的胸径-树高实测数据,利用SPSS 19.0拟合3种不同生长势杉木成熟林的胸径-树高模型。建立杉木优势木树高的幂函数模型,ln(H)=0.891×D0.376;杉木中庸木树高的幂函数模型,ln(H)=0.669×D0.504;杉木被压木树高的幂函数模型,ln(H)=0.643×D0.542。结果表明,3种非线性回归模型的判定系数R2都>0.910,D1.3能够很好解释各器官树高。对指导将乐地区杉木营林生产提供了疏伐选木的依据和抚育采伐开始及采伐强度的信息。
Abstract:
 This article was aimed at studying height & BDH conditions of Cunninghamia lanceolata afforested in the Forest Farm of Jiangle,Fujian Province.Mature standings of C.lanceolata with different growth potentials were selected to extract the real data of plus,intermediate and suppressed trees Models of tree height & BDH of the three trees were simulated: ln(H)=0.891×D0.376(plus tree),ln(H)=0.669×D0.504 (intermediate tree),and ln(H)=0.643×D0.542 (suppressed tree).The results indicated that the coefficient of determination (R2) of nonlinear regression models of three kinds were all greater than 0.910,D1.3 could commendably account for height of each organ.The results would provide the basis for the election thinning,tending,harvesting,and harvesting intensity.
