立木生长量估测是森林资源管理的重要环节,也是制定各项森林经营措施的科学依据。本文针对目前常用材积生长率公式在不同方面存在的不足之处,从材积生长率的定义式出发,根据立木材积与胸径之间的相依关系,提出了材积生长系数k值的概念。並通过拟合曲线方程,编制k值表,提出了新的材积生长率公式和测算方法——k值表法。
Estimation of standing tree growth is an important part of forest resources management and a scientific basis for formulating various forest management measures. In this paper, according to the shortcomings of the commonly used formulas of volume growth rate in different aspects, according to the definition of volume growth rate, the concept of k value of volume growth coefficient is put forward according to the relationship between standing volume and DBH. And through the fitting curve equation, the preparation of k value table, put forward a new volume growth rate formula and calculation method - k value table method.
