论单层同龄林分系统的耗散结构特性

Study on the Dissipation Structure of Identical Age and Single-storied Forest

林分系统的演变，必定是通过净生长量和死亡量的涨落，改变旧的（株数－蓄积量）结构，形成新的转化功能，再发生新的涨落，策动着将来的（株数－蓄积量）演变，这种生长运动导致林分的进化、发展，维持着非平衡态结构的稳定、有序。林分系统的时、空演变是多样化的，而坐标｛ｘ（株数）、ｙ（蓄积量）｝在“能级谱”上运动的方向和速度，既表现了林分（株数－蓄积量）结构的变化，又反映着能量演变的频率和动量产生的波长，说明演变具有波、粒二象性的特性。

A stand system change in the(number-volume)structure would be through going up and coming down of the growth increment and death volume,it will take a new convert function, which may instigate evolution(number-volume)of stands in fu-ture.This(structure-function)keeps to form an unbalance state,stableand in order ad-vancing stands system better than that of the past.Time-and-space evolution of stands system is changeable,which shows different di-versity,its{x(N),y(V)}evolution on the“Power Class Table” that react on its ratio of en-ergy change and wavelength. This indicates that there is the characteristics of wave and par-ticle change in the production of matter and energy of stands system.
