摘要
本文通过多种生长函数的拟合和比较,选择了Richards生长函数作为开化不同立地指数等级下杉木人工林平均胸径、树高和材积生长过程的基本模型。从拟合参数可知,不同立地条件下的林分平均胸径、树高和材积生长都是多形的。
By regressive result comparison, Richards function was selected as a basic model to fit the average individual growth process in DBH, length and volume of Chinese fir stands under different site index classes in Kaihua County. According to the regressive coefficient, the three growth curve groups above all were polymorphism.
