建立削度方程是编制材种出材率表的首选方法和基础。本文以海南省桉树、木麻黄、马占相思为研究对象,利用Ormerod（1971）提出的削度方程为基本削度方程,并在此基础上构建了可变参数削度方程进行模型研建。通过比较分析,结果表明：所建立的海南省桉树、木麻黄和马占相思3个树种的削度方程拟合效果均好,复相关系数基本上在0.96以上,预估精度在99.0%以上,无系统偏差,具有较好的适用性;且可变参数削度方程明显优于基本削度方程,是生产上的首选模型。

Taper equation is the preferred method and basis for the preparation of the volume table. In this paper, it takes Eucalyptus, Casuarina equisetifolia ,Acacia mangium of Hainan province as the research object, u- sing taper equation put forward by Ormerod in 1971 as basic taper equation, and base it to build the variable pa- rameters taper equation, then both results are compared. The results show that the fitting results of establishment of taper equations for Eucalyptus, Casuarina equisetifolia and Acacia mangium is very well, the multiple corre- lation coefficient is almost all above 0.96, estimated accuracy is more than 99.0%, there is no systematic bi- as, which has better applicability; established variable parameters taper equation is significantly better than the basic taper equation, which is the preferred model on the production.
