| 摘 要： | 为了解不同生境中台湾水青冈(Fagus hayatae)的群落特征,对四川米仓山国家级自然保护区不同海拔的台湾水青冈群落的物种组成、区系特征、生活型谱、重要值和物种多样性等进行了研究。结果表明,台湾水青冈群落中的植物种类随海拔存在差异。群落中植物区系均以北温带分布类型为主,且其分布比例与海拔呈正相关关系。不同海拔群落的物种生活型谱主要以高位芽植物为主,其它生活型较少。群落乔木层中台湾水青冈的重要值随海拔上升不断增大。中海拔群落中的物种多样性指数均低于高海拔和低海拔,具有物种种类少、多样性低的特点。因此,不同海拔段上的台湾水青冈群落学特征有明显的差异。

| Abstract: | The aim was to understand the characters of Fagus hayatae community in different habitats. The species composition, flora character, life form, importance value and species diversity along altitudinal gradient in Micangshan National Nature Reserve, Sichuan were studied. The results showed that species number in F. hayatae community was different with increment of elevation. The north temperate distribution was dominant in F. hayatae community, and the proportion of dominant floristic distribution had positive correlation with elevation. The main life-form spectrum was phanerophytes. The important value of F. hayatae in tree layer increased along altitude. The diversity indexes of F. hayatae community in middle altitude were lower than those in high and low altitudes, showing the characters of less species and low diversity. Therefore, the characteristics of F. hayatae community had obvious difference in different altitudes. |
