摘 要: 应用阶跃函数对连年生长量生长过程进行模拟,提出了确定最大连年生长量年龄的数学方法,从根本上解决过去图解法中受解析木断面位置和龄阶影响的问题。 Growth process of current annual increment by using step function was simulated. Mathematical method was put forward to determine the maximum annual increment. The root of the problems of location of cross section for analytic trees & age gradation in graphical method were solved.
