Lake Qinghai has thick layers of the sediment over the range of 10,000 years. In order to reconstruct the palaeoenvironment around the Qinghai-Tibet plateau, water content, TOC, OC isotopes of the sediment and ion concentration of Na+ and Cl- of the pore water were examined. They show fluctuations which can be interpreted as variations of the past primary products and productivity, salinity change, and perhaps humidity.
