大兴安岭林区针叶林的生长方程及火灾林木死亡率

THE GROWTH EQUATIONS OF CONIFER FOREST OF GREAT XING AN MOUNTAIN AND CHANGE OF TREE MORTALITY RATE BY FOREST FIRE

本文用随机模拟的方法建立了北方针叶林的生长方程及其受到火灾侵害后的林木死亡率，定量地研究了火灾对这种林分变动的影响．

Using the stochastic simulation method,the authors have established the growth equations of Northern Conifer forest area,and using these equations,the authors haveABSTRACTUsing the stochastic simulation method,the authors have established the growth equations of Northern Conifer forest area,and using these equations,the authors havesought for the change of mortality.rate when fire attack the forest area.By this way,the authors have discussed the change of forest sands which were affected by fire.This way also is applicable for these cases in which the forest stands were affected by some other factors such as airborne pollution,timber harvest and so on.
