| 摘 要： | 中国兴蒙—新疆北部及邻区中泥盆统发育，含丰富的动植物化石。根据门类生物群综合分析研究，将其古生物地理区划分出１个域，２个省，６个亚省（Ｉ旧世界域；Ｉ１哈萨克斯坦—蒙古—兴安省：Ｉ１１哈萨克斯坦—准噶尔亚省，Ｉ１２萨彦—阿尔泰亚省，Ｉ１３东蒙古—兴安亚省，Ｉ１４北天山来省；Ｉ２南天山省：Ｉ２１土尔克斯坦—阿赖亚省，Ｉ２２艾尔宾山—克孜勒塔格亚省）。哈萨克斯坦—蒙古—兴安省，以床板珊瑚类的土尔干槽珊瑚属广泛发育为主要特征；四射珊瑚以内板—角珊瑚动物群为代表；腕足类具明显的二分特征，早期属群与早泥盆世晚期特征相似，晚期以尖翼尖翼石燕动物群大量发育为主要特征；植物以原始鳞木植物群为特征。南天山省主要特征是全部为海相，没见陆相。床板珊瑚多为世界性分子，缺少土尔干槽珊瑚动物群分子；四射珊瑚以带珊瑚—魏得肯珊瑚动物群大量发育为特征；腕足类则以鹗头贝动物群大量发育为突出特征。此外，尚有丰富的层孔虫，它们与珊瑚多形成礁体。

| Abstract: | The Middle Devonian with rich fauna and flora was developed. According to the synthetic analysisof the fauna and flora, the palaeoblogeographic divisons of Middle Devonian cover one realm, two provinces,six subprovinces (I Old World realm, I1 Kazakstan-Junggar subprovince,I21Sayan-Altay subprovince, I31East Mongolin-Xingan subprovinbe, I41 North Tianshan subprovince;I2 South Tianshan province, I21Turkstan-Alai subprovince aam I22 Erbing Mis. -Kiiltag sndprovince). The Kazakstan-Mongolia-Xinganprovince is dominated by widely developed fauna and flora mainly consisting of the representatives ofTyrganolites (Tabulata), Endophyllum-Keriophyllum assemblage (Rugosa ),Mucrospirifer mucronatus (brachiopoda)and Protolepidodendron (flora). The South Tianshan is chararearized by marine sediments withoutany continental sediments.The Tedulsta is mainly composed of the cosmopolitan,lath of Tyraganolites;theRugosa is mainly of Zonophyllum-Wedekindiphyllum assemblage;the brachopoda is mainly of Stringocphalus.Additionally the abundant stramotoporids combine with corals to form reefs. |
