| 摘 要： | 植物天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。宝天曼自然保护区是我国北亚热带和暖温带的分界线，区内锐齿栎林结构稳定，但天然更新较难进行。锐齿栎种子产量大、活性高，且能够迅速发芽生长，占据有利的空间，但锐齿栎林的天然更新需要依靠适当面积的空旷地或裸地。

| Abstract: | Natural regeneration of vegetation is a complicated ecological process, which plays important role in the multiplication, spread and continuation of plant population and the stabilization and succession of plant community, and it has been a hotspot in the research of vegetation dynamics. Baotianman Natural Reserve is representative of North-South climatic transition zones. Quercus aeutidentata forests have stable structure. Natural regeneration is difficult to carry out within the Q. acutidentata forests. Natural regeneration of Q. acutidentata forests should rely on a large area of open land or bare land, though Q. acutidentata seeds can take advantage of their great number and high activity, which enable Q. acutidentata forests to develop rapidly, and take up the space. |
