摘  要：
对天然次生林顺行演替采取的经营措施的效果进行分析,结果表明:对过伐林实行封山育林,对火烧迹地实行天然更新,其森林演替效果显著.对过渡阶段的次生林实行抚育间伐效果进行分析,结果表明:间密留稀的抚育方式可以促进树木生长量的提高,有利于森林的顺行演替;采阔留针的作业方式造成土壤肥不足,森林生长速度减慢,森林结构不合理,森林质量下降.不同森林类型的养分流研究结果表明,阔叶树较落叶松纯林更有利于增加土壤肥力,保护森林生产力;阔叶树凋落物的分解速率大大高于针叶树,加速了树木生长和森林演替速度.藉于研究结果,对确定合理的天然次生林经营方式提出了建议.

摘  要：
The analysis on the effect resulted from management measures for positive evolution of natural secondary forest showed that the effect was remarkable when enclosure of the hillside for regeneration was implemented in over-logging forest and natural regeneration happened in burnt plots.The analysis on the effect of transitional secondary forest revealed that sparse nurturing promoted the timber increment,and was favorable for positive evolution.The means of broadleaved-logged and coniferous-left resulted in insufficient fertile soil,which slowed down forest growth and forest quality.The study on nutrient flows indicated that broadleaved trees were more beneficial for soil fertilizer than larch forest,which speeded up tree growth and forest evolution.Thus the paper proposed a suggestion on how to define reasonable management means for natural secondary forest.
