| 摘 要： | 本文通过调查统计和实验，对青冈种群动态进行了初步研究，包括种子库动态、种子萌发、无性繁殖以及密度调节等。研究表明，青冈种子量较大，但只有少数能发育成幼苗；有性繁殖和无性的克隆生长相互配合达到种群较高的繁殖效率；种群内个体的自疏定律说明，较成熟(40年左右)的青冈种群的增长速度已减慢。

| Abstract: | On the basis of investigation,experiment and census figure,the dynamic regulation of Cyclobalanopsis glauca were studied.It included the dynamic state of seed banks,seed sprouting,asexual reproduction and density regulation of C.glauca. The results showed that the number of C.glauca seed was larger,but only a few of them could sprout into seedlings in plant community. Seed production and asexual clonal growth cooperated with each other to make high reproductive effort.The self sparse of C.glauca showed that the growth speed of C.glauca population(about aged 40) was slowing down. |
