山东淄博煤田晚石炭世——早二叠世植物群落特征

山东淄博煤田晚石炭世—早二叠世植物化石经鉴定,共计37属104种,其中包括11个新种。分析了本区植物化石的埋藏类型,根据各类植物的生活习性和生境,将晚石炭世—早二叠世植物群划分为五个植物群落,讨论了它们的多度、成分、结构和生活型等特征,并采用信息函数数理统计方法,应用电子计算机对各植物群落的分异度和均衡度进行了计算。

Characteristics of Late Carboniferous and Early Permian Plant Communities in Zibo Coalfield,Shandong

Late Carboniferous and Early Permian fossil plants are assessed and counted 37 genera and 104 species including II new species in Zibo Coalfield, Shandong Province. And the buried types of fossil plants in this area are analyzed. According to their life habits and habitats, Late Carboniferous and Early Permian flora may be divided into five plant communities. And their abundance, composition, structures, life forms and others are discussed and the mathematical method of the Shannon index isadopted to calculate the diversity and equilibration of five plant communities with the computer.
