Abstract:
The 34 cm sediment core, which was recovered from Taro Co, southwestern Tibetan Plateau, was investigated. The multiple indicators in the sediment including the contents of total organic carbon, inorganic carbon, total nitrogen, trace elements and n-alkanes and the ratio of carbon and nitrogen contents were measured. Sedimentation age and rate were analyzed by the method of excessive 210Pb and 137Cs dating in order to obtain the continuous sequence of lake sedimentary environment over the past about 300 years. On condition that definitely understanding the climatic and environmental implications of the indicators, the indicators in sediment core were analyzed synthetically and comparatively. Then, the climatic and environmental changes in the region of Taro Co over the past about 300 years were reconstructed according to the dating results. The results showed that the climatic and environmental changes of Taro Co Region could be divided into three obvious stages. In the early stage from 1705 to 1778, the climate, which was warm and humid, fitted the vegetation best in the region. In the middle stage from 1778 to 1860, the last Little Ice Age came, and climate was wet and cold, and the growth of vegetation stopped in the region. In the last stage since 1860, the climate was warm and dry after the Little Ice Age in the region, and the stage could be divided into three small stages: from 1860 to 1924, the climate was dry and a little warm, and the vegetation grew a little; from 1924 to 1969, the climate was a little cold and dry, and the growth of vegetation stopped; since 1969, the climate was warm, and the drought was improved, and the vegetation grew gradually. The cold and warm alternately recorded by the sediments in Taro Co were highly consistent with that recorded by ice core in Guliya and lake sediments in Qinghai Lake; however, there were differences in the beginning and end years of the stages.
