摘　　要：以海南省松树、橡胶树为研究对象,利用Ormerod提出的基本削度方程模型结构,并在此基础上构建可变参数削度方程模型。通过对固定参数与可变参数削度方程模型的比较分析,可知:所建立的松树、橡胶树带皮和去皮削度方程拟合效果均很好,模型确定系数均达到0.93以上,预估精度在99%以上;而可变参数模型要明显优于固定参数模型,是生产中的首选模型。In this paper,taking two tree species(pine and rubber)in Hainan Province as research objects,and based on the basic taper equation model proposed by Ormerod(1971),the variable parameter taper equation models are establish.By comparing and analyzing the fixed and variable parameter taper equation models,it shows that there are better fitting effects for both pine and rubber tree taper equations of inside-outside bark which established.Their model determination coefficients all reach to above 0.93,the prediction accuracy more than 99%.The variable parameter model is obviously better than the fixed parameter one,which is the preferred model in actual work.
