1西藏南部普莫雍错19 cal ka BP以来高分辨率环境记录显示文摘利用西藏南部普莫雍错深水湖区获取的3.8m长湖芯,对湖芯中25个样品的植物碎屑进行筛选和有机碳同位素测定,在确定植物来源的前提下进行了14C测定,结合表层样品的过剩210Pb衰变计算的沉积速率对整个湖芯的14C测年及其碳库效应进行了系统校正,结果显示该湖芯完整地覆盖了19calkaBP以来的时间尺度.通过对湖芯TOC,IC,粒度和孢粉的分析,发现该湖在16.2calkaBP之前为一个水深较浅的湖泊,尽管温度升高导致冰川开始融化,湖区环境仍然具有冷干的特征;16.2~11.8calkaBP,沉积环境剧烈而频繁的波动,14.2和11.8calkaBP左右的2次冷事件可能是老仙女木和新仙女木事件的反映.11.8calkaBP之后,已经形成了现今状态的深水湖泊,冰川融水的补给使得湖泊水温较低,受到湖泊水体影响的沉积物环境代用指标对温暖条件的响应并不明显.通过普莫雍错湖与西藏南部相同时代的不同湖泊沉积物记录的比较,发现末次冰消期开始的气候转暖对青藏高原东南部影响更加显著,反映了西南季风自冰消期以后逐渐加强、向高原内部推移的过程,以冰川融水补给为主的湖泊对冷事件的响应更加明显.全新世以来,西南季风对整个西藏南部区域发挥着控制性影响.吕新苗 朱立平 NISHIMURA Mitsugu MORITA Yoshimune WATANABE Takahiro NAKAMURA Toshio 汪勇 2011科学通报2011,56,24:11
2A high-resolution environmental change record since 19 cal ka BP in Pumoyum Co, southern Tibet显示文摘A 380-cm-long sediment core was acquired from the deep water area of Pumoyum Co, southern Tibet. Twenty-five plant residue samples were selected, and organic carbon stable isotopes were obtained using the AMS 14 C chronological method. The 14 C age and carbon reservoir effect were calibrated with surface sedimentation rate measurements using 210 Pb dating. Results showed that the core sediment deposited over 19 cal ka BP. Based on a multi-proxy analysis of TOC and IC contents, grain size and pollen assemblage data, the palaeoclimatic evolution of Pumoyum Co was reconstructed since the last glacial. Pumoyum Co was a shallow lake prior to 16.2 cal ka BP; although the glacier around the lake began to melt due to increasing temperatures, climate was still cold and dry. In the interval of 16.2-11.8 cal ka BP, the sedimentary environment fluctuated drastically and frequently. Two cold-events occurred at 14.2 and 11.8 cal ka BP, and these may correspond to the Older Dryas and the Younger Dryas events, respectively. After 11.8 cal ka BP, Pumoyun Co developed into the deep lake as it is now. The lake water temperature was relatively lower at that time because of influx of cold water from glacial meltwater entering the lake. As a result, the multi-proxy indicators showed no sign of warm conditions. Comparisons between the sedimentary record of Pumoyum Co with that of other lakes of the same age in southern Tibet indicate a warmer climate following the last deglaciation influenced the southeastern Tibetan Plateau. These results imply that the southwest Asian monsoon gradually became stronger since the deglaciation during its expansion to the inner plateau. The glacial-supplied water of the lake responded sensitively to cold-events. The entire southern Tibet region was dominantly influenced climatically by the southwest Asian monsoon during the Holocene.LU XinMiao ZHU LiPing NISHIMURA Mitsugu MORITA Yoshimune WATANABE Takahiro NAKAMURA Toshio WANG Yong 2011Chinese Science Bulletin2011,56,27:10
