Effective moisture changes and landscape development on the north-eastern Tibetan Plateau during the last 50 ka inferred from Lake Donggi Cona lake sediments

青藏高原东北部稀少的古环境资料表明，该地区与其他季风影响区晚第四纪有效水分变化的一般规律有部分矛盾。本项目旨在研究青藏高原东北部区域水分变化的原因和后果。在青藏高原东北部野外考察(包括详细的湖盆调查)和初步古生态资料的基础上，我们在东吉柯纳湖盆地(35.3°N；98.6°E：4100m ASL)选择了三个取心点。探讨区域有效情绪变化的情况。在这一应用程序的框架内，我们计划从湖中提取三个沉积岩芯，并为进一步分析准备沉积材料。

Sparse palaeoenvironmental data from the north-eastern Tibetan Plateau revealed that thisarea partly contradicts the general pattern of late Quaternary effective moisture change knownfrom other monsooninfluenced areas. Our project aims to investigate the causes andconsequences of regional moisture change on NE Tibetan Plateau. On the basis of severalfieldwork surveys (including a detailed lake basin survey) on the NE Tibetan Plateau andpreliminary palaeoecological data, we have selected three coring sites in the Lake DonggiCona basin (35.3°N; 98.6°E: 4100 m asl.) to explore the circumstances of regional effectivemoisture changes. Within the frame of this application we plan to retrieve three sedimentcores from the lake and prepare the sediment material for further analysis.
