福建藤山自然保护区藤本植物多样性研究

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。

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

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.
