摘要
以浙江天目山金钱松自然群落为对象,采用典型样方法和每木调查法,对其群落植物种类组成、外貌特征、结构特征、多样性等进行研究。结果表明:天目山金钱松群落维管束植物种类丰富,涉及84科190属262种;群落属区系组成具有明显的温带性质,以温带成分占绝对优势,其次为热带成分;高位芽生活型植物占显著优势;不同群落类型均表现出较为稳定的结构特征,灌木层和草本层的物种丰富度明显高于乔木层;草本层指数明显高于灌木层和乔木层,而各层次的Simpson生态优势度指数和均匀度指数则较为接近,但金钱松种群自我更新出现"瓶颈现象"。
The floristic character, community appearance, community structure and species biodiversity of Pseudolarixamabilis communities in Tianmushan area in Zhejiang province were studied by using the method oftypical sample method and each wood investigation method. The result showed that there was rich vascular species diversityin the Pseudolarixamabilis communities in Tianmushan area, involving 84 families, 190 genera and 166 species. The flora displayed an apparent temperate characteristic.Phanerophytes were dominant in the life-form spectrum.The community structures of different community types were stable. And the species richness of shrub layer and herb layer is significantly higher than tree layer.Shannon-Wieners indices of herb layer is significantly higher than shrub layer and tree layer, while the Simpson dominance indicesand evenness indices in different layers were relatively close. Bottlenecks came into being in the self-renewal of Pseudolarixamabilis （Nelson） Rehd. species.
