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.

该项目的目标是重建青藏高原北方晚第四纪的气候和景观演变。该项目旨在对气候影响大不相同但集水特征相似的三个选定湖泊系统提出多学科方法。不同的档案沿着沉积路线（沉积级联）进行了研究，以了解气候变化对各种土地形成过程中明确界定的集水区的影响。在第一个资助期内获得的Donggi Cona盆地的研究结果提供了一个强大的湖泊集水过程和沉积环境之间的相互关系，在过去的20万年，其中并不是所有的影响，过去的季风气候。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地和湖泊记录，对青藏高原北方环境变化的多个方面进行系统的年代地层学研究。此外，多个分析，从第一个时期将合并到一个全面的过程响应模型的环境变化，在过去的20万年BP，应用到一个新开发的统计模型，由我们的小组。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，继续对更西边的Ayakhum湖进行研究。
