摘要: 本文总结和讨论了中国石炭纪和二叠纪植物群分布特征,在对植物群成分分析的基础上,认为中国早石炭世(杜内期、维宪期和纳缪尔A期)分布一个全球一致性的植物群,即拟鳞木植物群Lepidodendropsis flora。中国的晚石炭世(纳缪尔B_C期、维斯发期和斯蒂芬期)和二叠纪植物群为华夏植物群。本文还对北方华夏植物群亚区和南方华夏植物群亚区植物群进行了对比,并论述了这两个植物群在组成成分上的差异。

Abstract: This paper summarizes and discusses the characteristics of the distribution of the Carboniferous and Permian floras in China. On the basis of the analysis of the floral composition, the Early Carboniferous (Tournaisian, Visean, and Namurian A) flora is considered to be a global uniform flora: the Lepidodendropsis flora. The Late Carboniferous (Namurian B_C, westphalian, and stephanian) and Permian floras of China represent the Cathaysia flora. The paper makes the comparison between the floras of the northern and southern floral subprovinces and deals with the differences of the two floras in composition.
