林木转移轨迹与林分发展方程的解

Transition Locus of Tree and Solution for the Growth Equation of Forest-stand

该文引入林木在龄径平面中的转移轨迹的概念，通过讨论林木在龄径平面中的转移规律，研究林分直径结构和树龄结构的动态变化规律．在定常情况下，利用林木转移轨迹构造出林分发展方程的解，从而得到描述林分树龄和直径结构动态变化规律的一般的解析表达式．

The concept of transition locus of tree on the age-diameter plane is intreduced todeal with stand growth relating to the structure of diameter and age. Under the stationary condi- tion, the solution for growth equation of stand is constructed by employing the transition locus oftree,Thus a general analytical expression for describing structure change of diameter and age isobtained.
