摘要: 以福建省将乐县国有林场杉木成熟林为研究对象,通过建立16块杉木标准地来获取基础数据。采用比较符合生物学特性的Logistic方程和幂函数方程对生物量进行拟合,根据生物量平均数据,以D,DH为自变量,分别拟合了各个器官(树干、树根、树叶、树枝)和全株的Logistic方程和幂函数。根据残存平方和SSE、总相对误差RS、平均相对误差E1、平均相对误差绝对值E2,AIC,BIC 等6个检测评价指标进行方程的4选1筛选。筛选出的最优模型中,幂函数模型3个,Logistic函数模型2个。结果表明:其模型的相关判定系数R2均在0.925~0.932之间;单株杉木各器官生物量占整体生物量的比重由大到小为树干>树枝>树根>树叶。

Abstract: In this paper,the mature Cunninghamia lanceolata plantation of state-owned forest farms in Jiangle County of Fujian Province was taken as the research object and the basic data for each standard plot was obtained by establishing 16 standard plots.Biomass equation was simulated by Logistic equation and power function which are suitable for the biological characteristics.According to biomass average data and D,DH as independent variables,the Logistic equation and power function of different organs (trunk,root,leaf,branch)and whole-plant were simulated.Based on Residual Sum of Squares,Total Average Relative Error,Average Relative Error,Average Absolute Relative Error,Akaike Information Criterion and Bayesian Information Criterion,the best modle was selected from four modles.The best modle included 3 power function models (DH as independent variables),2 Logistic models (D as independent variables).The results show that1)The determination coefficient R2 of the model was between 0.925 and 0.932.2)The proportion order of different organ biomass in whole forest biomass was tree > branches > roots > leaves.

Key words: Cunninghamia lanceolata, mature forest, biomass model
