摘要：
三叶虫证据表明，除北疆区的阿尔泰地体和兴安区的额尔古纳—兴安地体与西伯利亚和劳伦陆块在动物群方面紧密关联外，中国奥陶纪的所有板块和大部分地体均系当时东泛冈瓦纳的重要组成部分，在生物地理上彼此密切相关。对这些属于东泛冈瓦纳的中国区块的台地或内陆棚三叶虫动物群的综合分析研究证明，它们在特马豆克期（Tremadocian）以及凯迪晚期—赫南特期（late Katian-Hirnantian）或阿石极期（Ashgill）应归属同一生物地理区，而在弗洛期—凯迪早期（Floian-early Katian）或阿仑尼克期—卡拉多克期（Arenig-Caradoc）则可划分为两个生物地理亚区：一个由华南、塔里木板块和安南或印支地体组成，另一个包括华北板块以及滇缅马、藏南、中天山—北山地体（可能还有海南地体）。饶有趣味的是在凯迪晚期或阿石极期开始发生的生物地理亚区解体之前，有关陆块的深水相三叶虫动物群已经历了从达瑞威尔中期（mid Darriwilian）至凯迪早期的长期频繁交流以及组成逐渐趋于齐一的过程。因此深水动物群之间的属种交流和一体化进程的发生、发展和完成显然均先于浅水一侧的三叶虫。
Abstract:
Trilobite evidence indicates that all the plates and most of the terranes in China exhibit a close biogeographic link and may have formed part of the eastern PeriGondwana during the Ordovician， except for the Altay Terrane of the Northern Xinjiang Autonomous Region and the ErgenHinggan Terrane of the Hinggan Region， where trilobite faunas show a strong affinity with those of Siberia and Laurentia. Synthetic analyses based largely on the platform/inner shelf trilobite faunas suggest that the Chinese eastern PeriGondwanan plates and terranes may have belonged to a single biogeographic province during the Tremadocian(Tremadoc)and the late KatianHirnantian(Ashgill)， but may be divided into two subprovinces during the Floianearly Katian(ArenigCaradoc): One consists of South China， Tarim and Annamia， and the other may include North China， Sibumasu， southern Tibet， TianshanBeishan and possibly Hainan. However， the deepwater facies trilobites of the relevant Chinese biogeographic units had progressively become more unified from the middle Darriwilian to the early Katian(Llanvirn to Caradoc)before the subprovinces eventually broke down by the late Katian(Ashgill). Therefore，the exchange of genus and species between deepwater facies animal assemblages and the onset， development and complishment of the process were obviously prior to those of the trilobites in shallow water.
