1藏南沉错湖泊沉积多指标揭示的2万年以来环境变化显示文摘通过对藏南沉错湖芯TC1孔的研究,分析了TC1孔的粒度、TOC、TN、C/N、Fe/Mn、Sr/Ba以及环境磁学参数等环境代用指标,基本上获得了这一地区2万年以来的环境变化记录.结果显示约19800~18000 Cal aBP的温度下降在各指标中具有明显的反映;约16000Cal aBP左右,温度在一次跃动上升之后,随即出现急剧下降;约15200~12000 Cal aBP,是降温之后的缓慢回升过程;约12000~9500Cal aBP,各种指标均显示湖区环境处于不适宜阶段,特别是11600~10400 Cal aBP,湖区环境显著恶化.进入全新世后,湖区环境经历了3次明显的暖期(约9 500~7600 Cal aBP、约6800~5800Cal aBP、约4800~3800 Cal aBP)和2次冷期(约7600~6800 Cal aBP、约5 800~4800 Cal aBP),呈现出暖干/冷湿的交替规律,具有南亚季风(西南季风)区气候变化的特征.沉错湖区2万年来的气候环境变化序列中的某些特征时段与格陵兰冰芯记录和青藏高原其他记录相比具有较好的一致性,反映了湖区及藏南地区的气候环境演变特征具有全球性特征.朱立平 王君波 陈玲 杨京蓉 李炳元 朱照宇 Hiroyki Kitagawa Gran Possnert 2004地理学报2004,59,4:38
