Vegetation-based climate reconstruction for the Tibetan Plateau: integrating vegetation modelling and pollen data reanalyses

亚洲季风系统控制着欧亚大陆大片地区的植被。青藏高原的环境特征反过来又会影响季风系统。在拟议的预测范围内，我们将研究青藏高原冰期至全新世期间千年尺度的气候变化和人类-气候变化的相互作用。建立青藏高原区域植被模型是本项目的一项关键任务，该模型将用于基于花粉推断植被变化的古气候的植被反演模拟。结果将与通过应用传统的花粉-气候转移函数进行量化的气候估计进行比较。所获得的气候时空格局将有助于我们理解青藏高原过去气候变化的原因和后果。此外，我们将调查“气候-植物-花粉”连锁链受到人类影响的严重程度，并将在数值气候推断方法中考虑这一点。该项目的研究结果将有助于理解“晚新生代气候演化和环境响应”和“人类影响和全球变化阶段”，这是优先计划“TIP”的两个要点。

The Asian monsoonal system controls the vegetation over a large area of Eurasia. The environmental properties over the Tibetan Plateau in turn affect the monsoon system. Within the proposed projected we will study the millennial-scale climate changes and human-climatevegetation interactions on the Tibetan Plateau during the glacial times to Holocene. It is a key task of our project to set up a Tibetan Plateau regional vegetation model that will be used for inverse vegetation modelling of palaeoclimate based on pollen-inferred vegetation changes. Results will be compared to climate estimates that were quantified by the application of traditional pollen-climate transfer functions. Obtained climatic pattern in space and time will contribute to our understanding of causes and consequences of past climate change on the Tibetan Plateau. Furthermore, we will investigate how severe the linkage chain “climate-vegetationpollen” is disturbed by human impact and will considered that in the numerical climate inference approaches. Findings from this project will significantly contribute to the understanding of the “Late Cenozoic climate evolution and environmental response” and the “Phase of human impact and Global Change”, which are two major points of the priority program “TiP”.
