The monsoon climate changes during the Holocene, a period characterized by civilization development, has a significant impact on the living environment of the human society, especially the alteration of drought and floods associated with the strength of the summer monsoon. A variety of medias, including lake, delta, and marine sediments, corals, loess, and stalagmite, have been used to reconstruct the evolution of the Holocene Asian monsoon. Due to the broad area of Asia and the regional variations in climate and human activities, a comp lete p icture of the Asian monsoon would be only drawn based on data integrated from extensive regional studies. The Chaohu Lake is a large shallow fresh water lake in the lower reach of the Yangtze River. Its evolution history contains information as to the paleoclimate and p laeoenvironment of northern subtrop ical climate zone. However, high2resolution records of Holocene environmental changes in this region are rare. In this study, a drill core (1615m in length)was obtained from the p resent coastal p lain of the Chaohu Lake, Eastern China, which covers the period of the Holocene according to AMS 14C dating. The top 800cm part of the core was used for multi2parameter rock magnetic and bulk particle size investigations, with the purpose to retrieve high2resolution information of Asian Monsoon evolution over the last 7000 years. The magnetic p roperties of core are dominated by magnetite grains. Sedimentation dynamics, which is largely controlled by p recip itation, p lays a significant role in the variations of magnetic p roperties in the lake sediments. In general, sedimentswith higher clay content are characterized by lower concentration ofmagnetic minerals and finer grain size, which are deposited in a period of higher lake level due to stronger rainfall and therefore stronger summermonsoon. In contrast, sediments with a higher fraction of > 32
