| 摘 要： | 新近纪是全球环境发生重大变化的时期，而青藏高原的形成与演变是亚洲乃至全球气候环境变迁的重要驱动力。认清新近纪哺乳动物从青藏高原到蒙古高原的分布规律和生态特征，是了解青藏高原隆升对我国地貌和气候的改造及其对全球气候格局的影响的重要手段。哺乳动物对气候环境的变化非常敏感，而中国在新近纪哺乳动物方面有着得天独厚的优势。临夏盆地和蒙古高原中部分别处于青藏高原隆升的堆积区和影响区，有广泛发育的能够反映隆升和古气候的沉积物，地层出露完好，保存有非常丰富的哺乳动物化石。在两个地区进行对比研究的结果对于理解全球新近纪一系列重大环境和生态事件，特别是青藏高原隆升以及亚洲季风形成和生物交流等问题具有重要科学意义。

| Abstract: | The Neogene was the period when the global environment had significant variations, and the formation and evolvement of the Tibetan Plateau were the important driving force for the changes of the Asian and even global environment. To recognize the distribution patterns and ecological characteristics of the Neogene mammals from the Tibetan to Mongolian plateaus is an effective method to know the alteration of the Tibetan Plateau’s uplift to the terrain and climate in China as well as the influence to the global climatic model. Mammals are very sensitive for climatic and environmental changes, and there are advantaged Neogene mammalian fossils in China. The Linxia Basin and central Mongolian Plateau are situated respectively in the sedimentary and affected regions of the Tibetan Plateau’s uplift, and there are well-exposed deposits to reflect the uplift and paleoclimate and very abundant mammalian fossils in the two regions. The result of comparative studies in the Linxia Basin and central Mongolian Plateau will have scientific significance to understand a series of important global environmental and ecological events during the Neogene, especially the uplift of the Tibetan Plateau, the formation of the Asian monsoon, and biotic dispersal and migration. |
