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.

青藏高原东北部稀疏的古环境资料表明，该地区晚第四纪有效湿度变化的一般模式与其它季风影响区的普遍模式部分矛盾。我们的项目旨在研究青藏高原东北部区域湿度变化的原因和后果。根据青藏高原东北部的野外调查（包括详细的湖盆调查）和初步的古生态资料，我们在东吉科纳湖（35.3°N; 98.6°E：4100 m）湖盆中选取了三个取样点。探讨区域有效水分变化情况。在这个应用程序的框架内，我们计划从湖泊中检索三个沉积物岩心，并为进一步分析准备沉积物材料。
