【摘要】 本文以植物群落调查样地资料为基础 ,从不同的类型、层次的丰富度、均匀度和多样性指标对山东胶南沿海地区的植物群落多样性进行了分析 ,分析表明 :本地区的植物生长型与群落多样性指数的关系表现为“乔木与灌木的丰富度指数相近且明显低于草本层 ,群落间变动幅度较小 ,乔木层则变动幅度很大 ;多样性指数多表现出草本层 >乔木层 >灌木层 ;群落物种多样性对小气候有一定影响 ,但与其区域环境有关。更多还原

【Abstract】 The richness indexes of different community types and vertical stratifications,evenness indexes and diversity indexes were analyzed on the basis of the research of the 13 plant in the coastal areas in Jiaonan City,Shandong Province.The results show as the following:The richness indexes of arbor layers are close to that of shrub layers,and they are all lower than that of herb layers,the waving range among associations small while that of the arbor is great.Mostly the biodiversity indexes revealed that herbaceous>the arbor>the bush because of false indigo dominating the shrub layer in the region.Due to the special habitats,the biodiversity indexes varied a lot among the communities.更多还原
