| 摘要: |
| 萨拉乌苏动物组合包括下部的萨拉乌苏动物群和上部城川动物群，前者含有水牛和古菱齿象等化石，属于晚更新世中期，环境较为温凉湿润；后者以野驴和披毛犀为主，属于晚更新世晚期，代表较干冷的气候环境。综合两者的动物组合、测年结果及其生态特点，显示前者应该是末次冰期中期的温凉湿润环境，而后者则应为末次冰盛期的前夜，应该是另一次Heinrich事件H2的动物组合。 |

| Abstract: |
| The animals combination of Sjara-Osso-Gol area can be divided into two faunas: the lower Salawusu Fauna and upper Chengchuan Fauna. The Salawusu fauna contains many fossil species, such as Bubalus and Palaeoloxodon, and belongs to middle of Late Pleistocene, and the environment is relatively cold wet. The Chengchuan Fauna is only few species with the Equus hemionus and Coelodonta antiquitatis, belongs to the late of Late Pleistocene, representing the dry and cold climate environment. Comprehensive both of the two combinations of animals, dating results and ecological characteristics, it is suggest that the former should be belong to the cold wet environment middle of the last glacial, while the latter is the cold dry eve of the last glacial maximum, should be another animals combination of H2 in Heinrich event. |
