英文摘要	植物的天然更新影响着群落的物种组成、结构和动态变化,是种群得以增殖、扩散、延续和维持群落稳定的一个重要生态过程;植物天然更新受环境条件、干扰(自然和人为),以及更新树种的遗传学、生理学、生态学特性及其与周围树种之间的关系等影响。植物在不同干扰条件下的繁殖对策可以反映植物对干扰的适应能力和生殖潜能,有助于理解植物对各种自然和人为干扰因素及其资源环境、生态
中文摘要	In order to identify the natural regeneration characteristics of C. sinensis populations in Langqi Island of Minjiang Estuary, young trees (with DBH less than 2.5 cm) were investigated by a line sampling method. The annual growth of both seedlings in forest gaps and root sprouts under the canopy was measured. The results showed seed propagation, root sprouting and stump sprouting were the main regeneration ways, accounting for 45%, 36.3%, 18.7% of the whole young population, respectively. The root sprouts were more than seed-derived individuals in young populations with the height less than 40 cm. Conversely, the number of seed-derived plants was larger than that of root sprouted ones in the population with the height higher than 40 cm. More young seedlings were observed in forest gaps than under the canopy. Seedlings were dominated in gaps, while other two types were dominated under the canopy. In addition, differences in both the annual height growth (P < 0.01) and annual ground diameter growth (P < 0.05) between seedlings in gaps and root suckers under the canopy were significant.
