福建藤山自然保护区藤本植物多样性研究

Studies on the Diversity of Lianes in Tengshan Nature Reserve of Fujian

研究了福建藤山自然保护区藤本植物地理分布、生活型特征,藤本植物多样性与环境因子、植被演替阶段的关系。结果表明:区内共有藤本植物233种,藤本植物资源丰富度高;植物区系以热带和泛热带成分为主;生活型以木质攀援藤本为主,占调查野生藤本植物种类50%,其次是缠绕型,占22 6%;从藤本植物种数和株数来看,以沟谷常绿阔叶林最多,沟谷常绿阔叶林>疏林>竹林>山地常绿阔叶林>针叶林,并随着海拔的升高而降低。

The results indicate that there are totally 233 species of lianes in Tengshan Nature Reserve of Fujian,the liane resource rich degree is high;the flora is mainly composed of tropical and pantropic components;the vegetative form is mainly composed of the woody climbing liane,which accounts for 50% of the investigated wild liane species,the second one is the voluble type,which accounts for 226%;in view of liane species number and tree number,those of channel and vale evergreen broadleaved forest are most,those change as follows:the channel and vale evergreen broadleaved forest>the open crop >the bamboo grove>the mountain everygreen broadleaved forest>the coniferous forest,and which decreases with the increase of elevation.
