所谓森林的生长规律是用树木或林分的生长函数来描述的。由于影响生长的因子大都是随机因子。故树木和林分的生长过程是随机过程。所谓生长方程是指在均值意义上的生长函数,它是树木或林分总生长量关于时间的确定性函数。 本文从树木直径生长理论方程——理查德(Richards)方程出发、并假设树木材积方程(即材积表)唯一确定条件下,由林分直径转移概率矩阵(由解析木资料估测的)导出林分直径分布状态转移方程。据此提出塔河地区主要森林类型(草类落叶松林,杜鹃落叶松林,矶蹲躅落叶松林,藓类落叶松林,草类樟子松林,杜鹃樟子松林,藓类云
The so-called law of the growth of forests is the growth function of trees or stands to describe. Factors that affect growth are mostly random factors. Therefore, the growth of trees and stands is a random process. The so-called growth equation refers to the growth function in the mean sense, it is the deterministic function of the total growth of trees or stands about time. Starting from the Richards equation of the tree diameter growth equation and assuming that the tree volume equation (volume chart) is uniquely determined, this paper derives from the probability matrix of the diameter of the forest stand (estimated from the analytical wood data) Stand diameter distribution state transfer equation Based on this, the main forest types (grass larch, rhododendrons, larch forests, moss larch forests, Pinus sylvestris var.
