摘要
更新是森林资源再生产的一个重要生态学过程,是森林生态系统动态研究的主要领域之一。本文从树种特性、生境因子、立地条件、干扰及森林空间异质性对更新的影响等方面综述了森林更新研究的进展情况。初步解析了森林更新过程中的障碍因子及其形成机制,指出现有研究存在的问题和下一步研究的思路。
Forest regeneration is the important ecological process of forest resources reproduction,which always been deemed to one of the major areas of forest ecosystem dynamics study.Forest regeneration research progress was reviewed from species characteristics,habitat factors,site conditions,interference and forest spatial heterogeneity.The obstacle factors and its formation mechanism in the process of forest regeneration were analyzed.The problems of the current study were pointed out and the direction of further research was suggested.
