浙江省丹霞地貌岩生植物群落物种多样性研究

采用样方调查的方法,对浙江省丹霞地貌岩生植物群落物种多样性进行了统计分析,以期为植被保护和生物多样性保护提供科学依据,结果表明:浙江省丹霞地貌岩生植被植物有82科143属195种;群落不同层次在Margalef丰富度指数、Simpson指数、Shannon-Wiener指数上,具有一致的趋势,即:草本层灌木层苔藓层藤本层;Pielou均匀度指数的排列顺序为:苔藓层藤本层草本层灌木层。不同区域群落物种多样性比较中,除苔藓层外,江郎山岩生植物各层次的丰富度指数和多样性指数都较高。

Species Diversity of Rock Plant on Danxia Landform in Zhejiang Province

In order to provide scientific data for vegetation and biodiversity conservation,species diversity of rock plant on Danxia landform in Zhejiang Province was analyzed by using methods of sampling and investigation.According to the data,there were 195 species,which belonged to 143 genera and 82 families.The changing trend in Margalef index,Simpson index and Shannon-Wiener index of the same community in dif ferent layers was clear,following the sequence of herb＞shrub＞moss＞liana;the order of Pielou index was moss＞liana＞herb＞shrub.Compared with the species diversity in different regions,the indexes of all layers on Jianglangshan Mountain were higher except the moss layer.
