摘要
在搜集国内外大量文献资料的基础上,综述种子缺乏,动物取食与侵害,植物化感作用,微生物致病,光照、温度、湿度、水分等生态因子异常,林下活地被物与枯枝落叶的物理阻隔,自然和人为干扰作用以及群落结构特征对森林天然更新的障碍机制,提出现有研究存在的问题和发展思路。
After reviewing a large quantity of literatures at home and abroad,the natural regeneration barrier mechanisms of forest were described,including lack of seed,animal eating and trespass,plants allelopathy,microbial pathogenesis,unusual state of ecological factors like light,temperature,humidity and rainfall,physical obstruct of understory groundcover and litters,natural and human disturbance and difference forest community characteristics.The paper finally came up with the problems existing in the current research and the development idea of the research.
