摘要: 本文研究广东石门台国家级自然保护区森林植被乔木层的植物种类组成,并对其中重要值最大的5种种群年龄结构进行探讨。结果表明,样地中胸径大于1.0 cm的植物177种(3593株),隶属于51科101属,其中重要值大于10的乔木树种5种,以山茶科、壳斗科和樟科等为表征科。优势种群的年龄结构中,疏齿木荷Schima remotiserrata、红锥Castanopsis hystrix种群为基本稳定种群;密花树Rapanea neriifolia、鼠刺Itea chinensis种群为增长种群;木荷Schima superba种群趋于衰退。整体上,石门台的常绿阔叶林森林植被种类组成复杂,结构较稳定。

Abstract: Species diversity and age structures of the most five dominant species populations within an evergreen broadleaved forest in Shimentai National Natural Reserve of Guangdong province were analyzed. The results showed that there were 177 species (3593 individuals) belonging to 101 genera in 51 families and with diameter of breast height more than 1.0 cm. Among the 177 species, there were five arbor species with important values more than 10, the characteristic families were Theaceae, Fagaceae, and Lauraceae, etc. For the age structures of dominant species, the populations of Schima remotiserrata and Castanopsis hystrix were basically stable, while the populations of Rapanea neriifolia and Itea chinensis was at increasing stage, and the population of Schima superba were towards early declined stage. In general, the species composition of evergreen broadleaved forest vegetation of Shimentai was complex, and the structure was relative stable.
