本研究主要针对南亚热雨林天然分布树种白楸(Mallotuspaniculatus)、枫香(Liquidambarformosana)、木荷(Schimasuperba)、薄叶润楠(Machilusleptophylla)和红栲(Castanopsishytrix)，从生理、形态和种群等几个层次研究幼苗更新对不同光照强度响应的机制，以期为理解南亚热带森林更新、物种多样性保持和生态恢复提供一些理论依据。采用透光率分别为100%(L100)、25%(L25)和8%(L8)的遮阴棚研究枫香、木荷、薄叶润楠和红栲的光合特征、脂膜过氧化作用、生物量累积和分配、高度生长、表型可塑性以及萌发和存活对不同光照梯...The aim of this study is to explore the response of seedling regeneration to light environmental herterogenety from physiological, morphological and population perspectives, and to improve the understanding of regeneration and species coexistence in subtropical forests and the practice of revegetation of degraded forests in south subtropical area. Several tree species were selected in this study, ...学位：理学硕士院系专业：生命科学学院生物学系_生态学学号：20022608
