| 摘 要： | 采用定量分析的方法对福建茫荡山自然保护区小叶青冈群落11个主要优势种进行了生态位研究,测定其生态位宽度、生态位相似比例等生态位特征值.结果表明：生态位宽度排在前6位的分别是小叶青冈、甜槠、木荷、弯蒴杜鹃、乌饭和深山含笑.小叶青冈与其他种群的生态位相似比例、生态位重叠值相对较高（猴头杜鹃例外）,表明它与其他种群之间的竞争相对激烈,易与生态位宽的树种形成共优群落.

| Abstract: | Through quantitative analysis,the author conducts ecological niche research on 11 dominant species of Cyclobalanopsis gracilis community in Mangdang Nature Reserve of Fujian province and determines the characteristic values of the niche such as width and proportional similarity specifically. The results are as follows：in terms of niche width,the top six species are Cyclobalanopsis gracilis,Castanopsis eyrei,Schima superb,Rhodoendron henryi,Vaccinium bracteatum,and Michelia maudiae. Except Rhododendron simiarum,the proportional similarity and overlap value of Cyclobalanopsis gracilis are relatively higher than other population,which reveals fierce competition with other populations and is prone to become mixed forest with those species that have broad niche. |
