 note = {Since 2001, six sediment cores have been collected from Lake Pumayum Co which is located in the southeastern region of the Tibetan Plateau, in order to reconstruct the paleoenvironment after Last Glacial Maximum (19-21 kyr B.P). In the present study, we aimed at organic-geochemically describing in detail the change of the lake water basin and the controlling factors using PY409 core (ca. 4m in length) which in preserving the paleoenvironmental record with the highest time resolution in the six cores from ca. 11,000 yr B.P to the present. For the purpose, a special attention was paid for calculating the mass accumulation rate (MAR) of terrigenous organic matter throughout the core. The vertical profile of the MAR, together with other various environment information, suggested the following. 1) The water basin of Lake Pumayum Co around 10,300 yr B.P reduced compared to that of present due to the much lower activity of water circulation in the southeastern region of the Tibetan Plateau. 2) For ca. 4,500 years from 10,000 yr B.P to 5,500 yr B.P, the water basin rapidly and more widely expanded than the present and kept constant by the wet and warm climate after Younger Dryas. 3) After 5,500 yr B.P, the water basin reduced to the dimension equivalent to the present level. This was caused by a decreasing water circulation., 第20回名古屋大学年代測定総合研究センターシンポジウム平成19(2007)年度報告<第2部> Proceedings of the 20th symposiumon on Chronological Studies at the Nagoya University Center for Chronological Research in 2007 日時:平成20 (2008)年1月10日(木)～11日(金) 会場:名古屋大学野依記念学術交流館 Date:January10th-11th, 2008 Venue:Nagoya Uhiversity Noyori Conference Hall},
