植物自然更新研究进展

植物自然更新是一个复杂的生态学过程,它对种群的增殖、扩散、延续和群落稳定及演替具有重要的作用,是植被动态研究的热点。目前国内外在这方面的多数研究主要从更新过程中的某一或几个阶段入手,分析各生态因子对更新的影响,或从林窗、火烧、动物等干扰对自然更新影响的角度揭示植被自然更新的机制。本文从植物自然更新方式、干扰对更新的影响及群落的更新等方面进行了总结,并提出了今后该领域的研究建议。

Research progress on natural regeneration of plants

Natural regeneration of vegetation is a complicated ecological process,which plays important roles in the multiplication,spread and continuation of plant population and the stabilization and succession of plant community,being a hotspot in the research of vegetation dynamics.At present,many researches at home and abroad are starting with certain or several stages in the process of vegetation regeneration to approach the effects of ecological factors on the regeneration,or trying to reveal the mechanisms of the regeneration from the aspect of the disturbances caused by forest gap,fire,and animal activities.This paper summarized the researches on the modes of the natural regeneration of vegetation,effects of disturbances on the regeneration,and the regeneration of plant communities.Some suggestions for the further study in this field were put forward.
