摘    要:在浙江省生态公益林区域的现状植被中分析了6种主要群落类型的物种组成和多样性的变化格局,包括演替系列中的2种灌丛、松优势林、2种混交林和常绿阔叶林。结果表明含松较多的灌丛和松优势林常分布在环境退化较严重(土层瘠薄)的生境中,其中灌木层主要由阳性的映山红、木、白栎等组成,常绿阔叶林优势种木荷、青冈、苦槠、甜槠等在其中偶见,因此推断其自然恢复为常绿林的速度慢;含常绿阔叶树较多的灌丛及含松较少的混交林分布在土层较厚处,木荷、青冈、苦槠、甜槠等的频度和重要值都较大,较容易自然恢复为常绿阔叶林。各种群落中物种多样性指数——Gleason、Shannon-Wiener、Simpson指数基本上以常绿阔叶林为最高,其次是含松较少的混交林,含松较多的灌丛和松优势林各种多样性指数最低。本研究显示我国中亚热带东部森林植被恢复途径有3条:(1)灌草丛→针叶林(松)→针(松)阔混交林→常绿阔叶林;(2)灌草丛→针(松)阔混交林→常绿阔叶林;(3)灌草丛→常绿阔叶林。这意味着本区域的常绿阔叶林恢复可以不必经历松林阶段,在生境条件较好的地方通过人工干预、补种常绿阔叶树可以加速常绿阔叶林恢复。

关 键 词:生态公益林  物种多样性  植被恢复途径  常绿阔叶林

Abstract:Public-welfare forests contribute many ecological benefits for the human community compared with the commercial woodlands. The vegetation of Zhejiang had been havoc in the 1950's. The composition and plant diversity of six major communities in ecological public-welfare forests of Zhejiang were analyzed used the sampling method. The six types are: shrubs contained more young pine trees (SMYPT), shrubs contained more young evergreen broad-leaved trees (SMYET), pine forest (dominated by pine trees, PF), mixed ...
Keywords:ecological public-welfare forests  species diversity  vegetation restoration  evergreen broad-leaved forest
