摘要：
木荷(Schima superba)为山茶科(Theaceae)的常绿乔木,有一定的耐荫性,耐脊薄干旱,适应性强，是我国中亚热带东部常绿阔叶林主要建群种之一。对该树种的研究目前主要集中在群落特征、遗传多样性、育苗及造林等方面，但对于不同生境下木荷的光合生理生态特性的研究还未见报道。本文在9月上旬的晴天里分别对林窗、林缘和林下3 种生境的木荷光合生理生态特性进行了研究。
关键词：木荷；不同生境；日变化；光响应；CO2响应
Abstract:
such as internal CO2 concentration, stomatal resistance and dark respiration rate were differences at different habitats, the understory leaves were far below others, but there was not distinct differences between canopy gap leaves and forest edge leaves; The curves of photoresponse had the same changes among three habitats, they could be better fit for quadratic equation with one unknown. Photosynthetic parameters of Schima superba in different habitats at different time or in the same habitat at different time showed that Schima superba has variation trends to adapt to environment.
Key words: Schima superba; different habitats; diurnal variation; photoresponse; CO2 response
