A continuous peat sequence collected in the southern Altai Mountains provides a new opportunity to reconstruct the Holocene vegetation and moisture history in the Arid Central Asia. Based on pollen data of 190 samples with a chronologic support of eight AMS dates from a 380-cm core at Tuolehaite (TLHT) Peat, the Holocene moisture variations in the southern Altai Mountains of China were reconstructed. The reconstruction revealed a wet early Holocene (10,600-8500cal. yr BP), a considerably dry middle Holocene (8500-4000 cal. yr BP) and a resumed wet late Holocene (~4000-0 cal. yr BP). The Holocene moisture reconstruction is generally corroborated by other reviewed sequences from the southern Altai Mountains and the surrounding areas. According to the analysis of modern sources of precipatable water vapor for the southern Altai Mountains, the Holocene moisture variations in the southern Altai Mountains were proposed to have been causally associated with the variations in the sea surface temperature (SST) in the North Atlantic Ocean and also with the variations in the strength of Siberian High Pressure in the core of the Eurasian continent.
在阿尔泰山南部采集的连续泥炭序列为重建中亚干旱区全新世植被和水分历史提供了新的机会。基于对 Tuolehaite（TLHT）泥炭 380 厘米长岩芯中 190 个样本的花粉数据，并结合 8 个 AMS 测年数据的时间支持，重建了中国阿尔泰山南部全新世的水分变化情况。重建结果显示，全新世早期（约 10600-8500cal.yr BP）气候湿润，全新世中期（约 8500-4000cal.yr BP）相当干燥，全新世晚期（约 4000-0cal.yr BP）恢复湿润。全新世水分重建与阿尔泰山南部及周边地区其他已发表序列基本一致。根据对阿尔泰山南部可降水蒸汽现代源的分析，阿尔泰山南部全新世水分变化被认为与北大西洋海表温度（SST）变化以及欧亚大陆中部西伯利亚高压强度变化有关。
