差分法在林学领域中的应用并不鲜见。铃木曾指出,在使用一阶差分方程式表示林木胸高直径生长的时序资料时,作为其解导出Mitscherlich式,其结果表明对于生长解析利用差分法是可行的。但是生长曲线论的主角是微分方程式。差分方程式中看到的差分这个用语,一言蔽之,是从微分中去掉极限概念的东西,假如生长的最小时间单位为有限的一年,以这 The application of difference method in the field of forestry is not uncommon. Suzuki has pointed out that when using the first-order difference equation to represent the time-series data of the diameter growth of chest height and height, Mitscherlich’s formula is derived as a result of which it is feasible to use the difference method for the growth analysis. However, the protagonist of growth curve theory is the differential equation. The term difference in the differential equation, in short, is something that removes the notion of limits from differentiation. If the minimum time unit for growth is a finite one,
