| [摘要]青藏高原的隆升导致了地表自然环境的变化和与环境密切相关的沉积记录。本文重点
对冈底斯中段第四系湖积阶地及剖面进行了研究,并采获了大量的孢粉和铀系等时线年龄值、ESR 年龄
值,通过分析冈底斯中段第四系的沉积环境,探讨了青藏高原隆升对第四纪的气候及生态环境影响:青
藏高原的隆升不但使高原山区发生多期冰川作用,如且导致了黄土高原、亚洲内陆戈壁、大沙漠的形成,
使高原湖泊退缩、湖面下降、湖泊向盐湖演变,一些外流水系也转化成内陆水系,形成了与之相适应的多
种多样的生态系统,同时也形成了一个独特高原气候区,其结果使高原隆升的气候效应扩大到全球,青
藏高原的隆升导致的环境变化对全球环境具有敏感响应和强烈影响。 |

| Abstract:The uplift of the Qinghai-Tibet Plateau has led to changes on the surface of the natural environment and closely related sedimentary re鄄
cords. This article focuses on Quaternary lacustrine terraces and profiles in central section of the Gangdise. A large number of pollen and U-Series dating
and the ESR age data have been collected. By analyzing the Quaternary sedimentary environment of the middle Gangdese, we study the effects of the Qing鄄
hai-Tibet Plateau uplift on the Quaternary climatic and ecological environment. The uplift of the plateau not only led to several periods of glaciation that
occurred in mountainous areas, but also resulted in the formation of Loess Plateau, the Asian inland Gobi and large deserts. It has caused the retreation
of highland lakes, dropping of lake surface and the evolution toward salty lakes. Some drainages also changed into inland water systems, forming a corre鄄
sponding variety of ecological systems, as well as a unique plateau climate. As a result, the climatic effects of plateau uplift extend to the whole world,
leading to the global environment change with a sensitive response to and a strong influence on the global environment. |
