| Abstract: | Based on the results of multi environmental proxies (chronology, pigments, diatom concentration, stable isotope of organic carbon, magnetic susceptibility, chemical element) of lake sediment from Erhai Lake, Yunnan Province, the series of climatic variations in the catchment of Erhai Lake during the past 1800 years has been established. The climatic changes with warm dry and cold wet alternations in Erhai Lake are different to the loess records in East Asia monsoon with warm wet and cold dry features. The characteristic periods such as the medieval warm period and Little Ice Age are both recorded in the lake sediments from Erhai Lake. The climatic characteristics with warm dry and cold wet alternation from the lacustrine records in Erhai Lake have the regional feature in Yunnan Plateau affected by southwest monsoon on the century scale. The lake sediment from Erhai Lake is rich with information of human activities. The proxies such as magnetic susceptibility, chemical element Fe, pigments have close relationship with the human activities during the historical period. The method of multi environmental proxies analysis is useful to determine the response of climatic changes and human activities, which has important significance for the research as well as rational explanation on the high resolution records of lacustrine sediment in the past 1800 years. |
