【摘要】 本文依据中国晚石炭世四射珊瑚组合特点及其分布规律,以属为基础进行统计和比较,将中国晚石炭世四射珊瑚划分为三个生物地理大区:特提斯大区、北方大区和冈瓦纳大区。特提斯大区包括华夏区,下分华南省、塔里木-藏北省和华北-祁连省,以暖水型单体和群体珊瑚为主。北方大区仅包括准噶尔-兴安省,以小型单体珊瑚繁盛为特征。冈瓦纳大区包括喜马拉雅-冈底斯省,仅出现冷水习性的小型单体无鳞板珊瑚。更多还原

【Abstract】 In the present paper, upper carboniferous rugose coral faunas of china are analyzed on the level of genera and their biogeography is studied by comparison of endemism percentage and otsuka similarity coefficient of different regions.Three biogeographic realms, the Tethyan, the Boreal and the Gondwanan, are recognized in China. The tethyan realm includes the cathaysian region, which can be further divided into three provinces:the South China, the Tarim-North Tibet and the Noth China-Qilian. Its rugose coral faunas are characterized by Chinese genera which are compound and solitory corals with dissepiments. The Boreal realm comprising Junggar-Xingan province is dominated by many small and solitory rugose corals. The Gondwanan realm Containing the Himalaya-Gandise province is predominated the cold water fauna consisting of small solitory corals without dissepiments.更多还原
