摘 要 ：先锋种和非先锋种可能对林窗产生不同的反应。在广东南澳岛4个不同的森林群落样地里移植了大叶相思（Acacia auriculaeformis A. Cunn.）、尾叶桉（Eucalyptus urophylla S. T. Blake）和荷木（Schima superba Gardn. et Champ）3种树苗，其中大叶相思和尾叶桉是先锋种，而荷木是非先锋种,测定了林窗和非林窗生境中的透光率和幼苗生长高度。结果表明，林窗的透光率大于非林窗的；各群落的透光率有季节性的变化，变化幅度各不同。3种幼苗在林窗内比
Abstract:Tree seedlings of pioneer species and non-pioneers may respond differently to canopy gaps. We used a field experiment to test this in four forest communities in Nan‘ao Island, Guangdong, China. We measured the ratio of light penetration (RLP) in gaps and
