开化王山阔叶林采种基地森林群落结构研究

Study on Community Structure of Broadleaf Seed Base at Wangshan Mountain of Kaihua

对开化王山阔叶林采种基地集约经营区进行群落学调查,结果表明其植物种类丰富,乔木层有93种,灌木层有20种,草本层有20种,层间植物有16种,乔木层灌木层优势种不明显,Simpson生态优势度指数低,乔木层相对重要值超过5%的有甜槠、木荷、马银花、红楠、东南石栎5种,甜槠最高占11.34%;草本和层间植物较单调优势种明显。常绿种类幼乔比高,落叶种类幼乔比低。

Study on community structure of broadleaf seed base at Wanshan Mountain of Kaihua, Zhejiang province showed that the base is located at subtropical evergreen broadleaf forest with rich plant species, no evident dominant tree or shrub at these two layers, low Simpson ecological dominant index, 5 tree species over 5% relative importance value of arbor layer, 11.34% of Castanopsis eyeri. Few plants between layers with dominant plant species. Young and adult tree ratio of evergreen species were high but low of deciduous one.
