全球石炭纪和二叠纪植物地理分区

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，即拟鳞植物区（Ｌｅｐｉｄｏｄｅｎｄｒｏｐｓｉｓ ｆｌｏｒａｌ ｐｒｏｖｉｎｅｃｅ）。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 ｐｒｏｉｎｃｅ）

Phytogeographical Provinces of the Carboniferous and Permian in the World

In the Early Carboniferous, the global climatic differentiations were not obviou s as today and all plants belonged to a uniform phytogeographical province, the Lepidodendropsis floral province. There were four phytogeographica l provinces in the world during the Late Carboniferous and Permian, e.g., the C athaysian 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 flo ral province was located in Gondwana of the Southern Hemisphere. This paper deal s with some major issues of Carboniferous and Permian phytogeographical province s in the world, attempting to provide palaeobotanical evidence for palaeocontin ental reconstruction.
