林分的经营密度,是指现实林分株数(或间伐后保留株数)占最大密度株数的百分数;而适宜经营密度,就是使林分生长量达最大时的密度.在抚育间伐生产中,能否掌握林分的适宜经营密度,不仅关系到间伐后林分的生长、发育、稳定性和蓄积的增加,同时也与维护森林的生态平衡和永续利用密切相关.本文试就雪岭云杉林的适宜经营密度进行探讨.
The management density of stands means the percentage of the actual stands (or retained after thinning), which accounts for the percentage of the maximum density, while the suitable management density is the density at which stand growth is maximized. In tending thinning production, Grasping the proper management density of the forest is not only related to the growth, development, stability and accumulation of the stand after thinning, but also is closely related to the maintenance of the ecological balance and sustainable use of the forest.This paper, The suitable management density of forest is discussed.
