Abstract The lack of a precisely-dated, unequivocal climate proxy from northern China, where precipitation variability is traditionally considered as an East Asian summer monsoon (EASM) indicator, impedes our understanding the behaviour and dynamics EASM. Here we present well-dated, pollen-based, ~20-yr-resolution quantitative reconstruction (derived using transfer function) alpine lake in North which provides for first time direct record EASM evolution since 14.7 ka (ka = thousands years...
ABSTRACT We present a pollen‐based precipitation reconstruction and multi‐proxy records from 485‐cm‐long sequence sediment core Xingyun Lake, Yunnan Plateau, south‐west China, which depicts the evolution of Indian Summer Monsoon (ISM) during last 8500 years. Pollen other palaeoenvironmental document several stages vegetation history climate change. The warmest wettest in Lake catchment occurred before 5500 cal BP, subsequently became gradually drier. After 2000 BP regional environmental...
The Artemisia/Chenopodiaceae (A/C) ratio is assumed to be a useful index for reconstructing moisture changes in arid and semi-arid regions. Thorough modern pollen studies are still lacking understand the reliability limitation of A/C as indicator, however. Here we review how well this can applied China on basis new surface data, previous data synthesis other publications. Results indicate that variance permit identification vegetation types generally has positive relationship with annual...
Abstract A comprehensive understanding of the regional vegetation responses to long‐term climate change will help forecast Earth system dynamics. Based on a new well‐dated pollen data set from Kanas Lake and review published records in around Altai Mountains, dynamics forcing mechanisms are discussed. In forest optimum occurred during 10–7 ka for upper zone tree line decline and/or ecological shifts were caused by climatic cooling 7 ka. lower zone, reached an middle Holocene, then increased...
How climate change in the middle to late Holocene has influenced early human migrations Central Asian Steppe remains poorly understood. To address this issue, we reconstructed a multiproxy-based history from sediments of Kanas Lake and neighboring Tiewaike southern Altai Mountains. The results show an exceptionally warm during ~6.5-3.6 kyr is indicated by silicon isotope composition diatom silica (δ30Sidiatom) biogenic (BSi) content. During 4.7-4.3 kyr, peak δ30Sidiatom reflects enhanced...
The ecosystems of the Qinghai-Tibetan Plateau are regarded as being primarily regulated by climate because harsh environment region and resulting sparse human population. Recent studies have revealed that Neolithic farmers nomads extensively settled in northeastern from 5.2 ka (ka = cal BP); however, it is unclear how to what extent activity has affected its vegetation. Here we combine results pollen analysis a sediment core Genggahai Lake, shallow lake Gonghe Basin on Plateau, with...
Abstract Initiation and development of pastoralism in northern China, the mechanisms involved, are poorly understood. Here we use analyses Sporormiella ‐type coprophilous fungal spores a well‐dated sediment core from Lake Gonghai together with other sequences to reconstruct population dynamics large herbivores during Holocene. Comparison results paleoclimatic zooarchaeological records suggests that grazing appeared at ∼5.7–5.5 ka further intensified again after ∼4.2–4.0 ka. The changes...
