森林天然更新影响因子研究进展

天然更新是森林资源再生产的一个重要的生态学过程,对种群的增殖、扩散和群落稳定及演替具有重要的作用。目前国内外的研究主要从天然更新过程中的某一个或几个阶段入手,分析各生态因子对天然更新的影响。从树种特性、环境条件、林分条件和干扰对天然更新的影响进行了综述,简要介绍了天然更新的影响因子。

Research progress on influence factors of forest natural regeneration

Natural regeneration is an important natural ecological process of forest resources reproduction,which plays important roles in the multiplication,spread,stabilization and succession of the population.At present,many researches at home and abroad started with a stage or stages affecting the process of natural regeneration to approach the effects of ecological factors on the natural regeneration.The effects of species characteristics,environmental conditions,stand conditions and disturbances on the natural regeneration were summarized and factors influencing natural regeneration were briefly introduced.
