建立树干削度方程已成为编制材种出材量(率)表的首选方法和基础工作,同时,削度方程具有日益取代普通立木材积表的趋势。为了适应我国林业进一步深化改革的需要,全面开展林业基础数表标准化工作,本文在概述国内外削度方程的研究历史与现状的基础上,划分了削度方程的种类,系统地论述了各类削度方程的特点和性质,分析、评价了几个具有典型意义的树干削度方程。
The establishment of the tree trunk taper equation has become the preferred method and basis for the compilation of timber seedling yield tables, and at the same time the taper equation has the tendency to replace the common wood timber table. In order to meet the need of forestry further deepening reform in our country and carrying out the standardization of forestry basic numerical tables in an all-round way, this paper summarizes the history and current situation of research on domestic and foreign taper equations, classifies the types of taper equations, systematically discusses various types Tapping equation characteristics and nature of analysis, evaluation of several typical significance of the trunk taper equation.
