摘要
On the basis of analysis of δ18O values of single ostracod shells Eucypris inflate retrieved from the sediments of Qinghai Lake in China, together with the established dating data, this paper discusses the mechanism of climate changes in the Qinghai Lake area during the past 1 000 years. The result suggests that δ18O values of ostracod shells reflect the variations of dry/flood, and the negative correlation between precipitation and the dry/flood index indicates that δ18O values of ostracod shells can be used to deduce precipitation variations.
