摘 要 ：早石炭世由于全球气候分带不明显,无显著植物分区现象,全球为一个一致性的植物区,即拟鳞木植物区[WT5”BX](Lepidodendropsis [WT5”BZ]floral province)。晚石炭世和二叠纪,全球存在4个植物区,即华夏植物区(Cathaysian floral province)、欧美植物区(Euramerican floral province)、安加拉植物区(Angaran floral province)和冈瓦纳植物区(Gondwanan floral province)。华夏、欧美和安加拉植物区皆位于北半球的劳亚古陆(Laurasia), 冈瓦纳植物区位于南半球的冈瓦纳古陆(Gondwana)。本文通过对全球石炭纪二叠纪植物地理分区的一些焦点问题的综合评述和分析,试图为古大陆再造研究提供古植物学方面的证据。

Abstract:In the Early Carboniferous, the global climatic differentiations were not obvious as today and all plants belonged to a uniform phytogeographical province, the Lepidodendropsis floral province. There were four phytogeographical provinces in the world during the Late Carboniferous and Permian, e.g., the Cathaysian floral province, Euramerican floral province, Angaran floral province and Gondwanan floral province. The Cathaysian, Euramerican, Angaran floral provi nces were situated in Laurasia of the Northern Hemisphere and the Gondawanan floral province was located in Gondwana of the Southern Hemisphere. This paper deals with some major issues of Carboniferous and Permian phytogeographical provinces in the world, attempting to provide palaeobotanical evidence for palaeocontinental reconstruction.
