VEGETATION AND CLIMATE CHANGES IN CENTRAL ASIA DURING OVER THE LAST 28,000 YRS: A HIGH-RESOLUTION POLLEN RECORD FROM VALIKHANOV SECTION, KAZAKHSTAN

摘要：

A high-resolution pollen-based bioclimatic reconstruction from Valikhanov section in Kazakhstan, supported by 6 AMS dates reveals vegetation and climate change history during last glaciations and Holocene.The vegetation probably was Artemisia arid steppe during ～28,000 - ～18,000 14C yr BP., then turned to be Artemisia steppe during ～18,000 - ～ 10,000 14C yr BP, an Atermisia-Chenopodiaceae desert steppe during ～10,000 - ～5,000 14C yr BP and a Chenopodiaceae-Artemisia steppe after ～5,000 14C yr BP in this region.Climate is cold and slightly wet during 28,000-10,000 14C yr BP., dry and mild during 10,000-5,000 14C yr BP., wet after ～5,000 14C yr BP in this region.Climate in the Central Asian domain was constantly wetter than that in the East Asian domain during MIS2.The Central Asian domain experienced a wetter climate in late Holocene whereas the East Asian domain expereinced a wetter climate in early Holocene.Climate in the Central Asian domain was constantly wetter than that in the East Asian domain during MIS2.The Central Asian domain experienced a wetter climate in late Holocene whereas the East Asian domain expereinced a wetter climate in early Holocene.
