摘要
该文论述削度方程的类型及其在研制材种出材率表中的重要意义,也论述了林分直径分布在林分结构、森林调查及研制林分材种出材量表中的重要作用。介绍了使用一致性削度方程和Weibull直径函数研制材种出材率表和林分材种出材量表的技术和方法。对于研制材种出材率表和材种出材量表的一些技术和方法问题也进行了讨论。
This paper discusses the various types of taper equations and their significance in developing merchantable volume tables. Additionally, stand diameter distributions are discussed in relation to stand structure, forestry inventory, and in order to formulate stand merchantable volume tables. The technique and method of developing stand merchantable volume tables and merchantable volume tables are introduced with the compatible taper equation and Wiebull diameter function. The problems of technique and method in formulating these tables are also discussed.
