Landscape and Lake-System Response to Late Quaternary Monsoon Dynamics on the Tibetan Plateau - Northern Transect -

该项目的目标是重建藏北高原晚第四纪气候和景观演变。该项目旨在对气候影响截然不同但集水区特征相似的三个选定湖泊系统采取多学科方法。研究了沿泥沙路线(泥沙瀑布)的不同档案，以了解气候变化对明确界定的集水区内各种土地形成过程的影响。东吉柯纳盆地在第一个资助期获得的研究结果表明，湖泊集水过程与最后20 ka期间的沉积环境之间存在很强的相互关系，其中并不是所有的沉积环境都受到过去季风气候的影响。通过重建所有相互依赖的过程，我们将能够综合土地形成过程及其对气候强迫的反应。我们将结合不同类型的陆相和湖泊记录，提供青藏高原北部多方面环境变化的系统年代地层学。此外，第一阶段的多项分析将合并为一个关于过去20 ka BP期间环境变化的综合过程-响应模型，该模型应用于我们小组新开发的统计模型。在第二步中，我们将通过使用和改进以前成功应用的相同方法来继续对更西边的阿亚库姆湖进行研究。

The objective of the project is the reconstruction of late Quaternary climate and landscape evolution on the Northern Tibetan Plateau. The project aims to contribute multidisciplinary approaches on three selected lake systems of quite different climate influence but with similar catchment characteristics. Different archives along sediment routings (sediment cascades) are studied in order to understand the impact of climate change on various land forming processes within well defined catchments. Research results from the Donggi Cona Basin obtained during the first funding period provide a strong interrelationship between lake catchment processes and the depositional environment during the last 20 ka, of which not all was affected by past monsoon climate. By reconstructing all interdependent processes, we will be able to synthesise land forming processes and their responses to climate forcing. We will provide a systematic chronostratigraphy of manifold aspects of environmental change on the northern Tibetan Plateau, combining different types of terrestrial and lacustrine records. Moreover, multiple analyses from the first period will be merged towards a comprehensive process-response model of environmental changes throughout the last 20 ka BP, applied to a newly developed statistic model by our group. In a second step we will continue research on the Lake Ayakhum farther west by using and improving the same approaches, successfully applied before.
