基于"驻留生态位"杉木天然更新研究进展
Research progress on natural regeneration mechanism of Chinese fir
森林天然更新是利用大自然进行森林恢复重建的生态学过程,是杉木人工林实现自我繁衍的重要途径。目前,我国森林更新仍以人工更新为主,受生境异质性、种源、凋落物、人为干扰以及群落的差异性等多因素影响。随着人工林成熟期的到来,杉木人工林的衰退与天然更新困难的问题逐渐显现,更新问题也逐步成为杉木人工林发挥其生态作用的主要因素,如何保证杉木天然更新尤为关键。本文就森林天然更新方式及杉木人工林更新障碍的研究进展进行综述,着重总结了杉木天然更新的影响因素,如光照、…查看全部>>
Forest natural regeneration is an ecological process of forest restoration and reconstruction using nature,and it is an important way for Chinese fir plantation to realize self-reproduction.At present,forest regeneration in China is still dominated by artificial regeneration,which is affected by many factors such as habitat heterogeneity,provenance,litter,human disturbance and community diversity.With the arrival of the mature period of Chinese fir plantatio…查看全部>>
