一引言本次研究的目的是检查生长方程对单株树木半径生长的适用性。首先,把现有的生长方程依其理论特性分成几组,逐组检查作初步筛选;其次,把选出的方程组应用于所观测树木的半径生长,以便从不同的观点诸如拟合优度、理论与实用的一致性等方面检验其适用性。
I. INTRODUCTION The purpose of this study was to examine the applicability of the growth equation to individual tree radius growth. First, the existing growth equations are divided into several groups according to their theoretical characteristics, and the initial screening is conducted by group inspection. Secondly, the selected equations are applied to the radius growth of the observed trees so as to obtain the optimal growth from different points of view, such as the goodness of fit , Theory and practical consistency and other aspects of testing its applicability.
