摘　　要：对床板珊瑚化石群的分析表明 ,南天山阿尔皮什麦布拉克组的地质时代为早泥盆世早期 ,所含珊瑚群与滇西北、西秦岭、内蒙古达尔罕茂明安联合旗、吉林二道沟的珊瑚群面貌相似 ,明确属于古特提斯生物地理区内 ;而与北天山、准噶尔、北山、大、小兴安岭等地区同期地层所产者存在明显差异。In eastern South Tianshan, the age of the Arpishmebulaq Formation with Tabulata is defined again as Late Lochkovian, Early Devonian. The corals from the Arpishmebulaq Formation differ from those of the equivalent horizons in the Junggar-Hingan biogeographic region but are similar to those from the Shanjiang Formation in Lijiang County, Yunnan, the Xiaputonggou Formation in Zoige County, Sichuan, the Alugong Formation in Darhan Mumingan Joint Banner, Inner Mongolia and the Erhtaokou Formation near Jilin City, Jilin. During early Early Devonian in China, a big biogeogogphic region is situated to the south of the Junggar-Hingan biogegraphic region, and this region, including South Tianshan, Central Jilin, south Inner Mongolia, West Qiling Mountains and northwest Yunnan etc., should belong to the Palaeotethyan Province of the Old World Realm.
