英文摘要	Understanding long-term environmental changes under natural and anthropic forces is helpful for facilitating sustainable development. Here we present a sedimentary record from the central Tibetan Plateau to investigate the impacts of climate and human activities on alpine vegetation during the late Holocene, based on a 162-cm-long lacustrine sediment core collected from Tangra Yumco. Palynology, charcoal and minerogenic input reveal variations of climate and human activity during the past 3400 cal yr BP. Our results show that alpine steppe dominated by Artemisia, Cyperaceae and Poaceae was present in the Tangra Yumco area during the entire covered period. Only minor human activities are visible between 3400 and 2300 as well as from 1700 to 400 cal yr BP, when vegetation was mainly influenced by climate. Although human activities (presence/grazing) became more intensive between 2300 and 1700 cal yr BP corresponding to the Zhang Zhung Kingdom, vegetation change is still mainly affected by a more arid climate. Strongest human influence on vegetation was found after 400 cal yr BP, when vegetation composition was altered by farming and grazing activities. Our records indicate human activities did not have significant impacts on alpine environment until the past few centuries at Tangra Yumco on the central Tibetan Plateau. (C) 2019 Elsevier B.V.
