“…Records from Tian'E Lake (in the Qilian Mountains) and BYBS profile (in the western part of the Badain Jaran Desert) show a decrease in moisture during 400 BCE-1100 CE and an increase in moisture from 1100 BCE to 1800 CE, which was in antiphase to the moisture record at Sugan Lake (Figures 6B, C, E). An increase in moisture during 1100-1800 CE at Tian'E Lake and BYBS profile may be due to the weakening of the Asian Summer Monsoon caused by the reducing solar radiation (Steinhilber et al, 2012;Gao et al, 2020). In general, a wetting record from Jili Lake over 2400 years (Figure 6A) is obviously different from that in the monsoon marginal region.…”

Regional humidity is important for terrestrial ecosystem development, while it differs from region to region in inland Asia, knowledge of past moisture changes in the lower basin of northern Xinjiang remainly largely unclear. Based on a pollen record from Jili Lake, the Artemisia/(Amaranthaceae + Ephedra) (Ar/(Am + E)) ratio, as an index of regional humidity, has recorded four relatively dry phases: 1) 400 BCE to 1 CE, 2) the Roman Warm Period (RWP; c. 1–400 CE), 3) the Medieval Warm Period (MWP; c. 850–1200 CE) and 4) the Current Warm Period (CWP; since 1850 CE). In contrast, the Dark Age Cold Period (DACP; c. 400–850 CE) and the Little Ice Age (LIA; c. 1200–1850 CE) were relatively wet. Lower lake levels in a relatively humid climate background indicated by higher aquatic pollen (Typha and Sparganium) after c. 1700 CE are likely the result of intensified irrigation for agriculture in the catchment as documented in historical records. The pollen Ar/(Am + E) ratio also recorded a millennial-scale wetting trend from 1 CE to 1550 CE which is concomitant with a long-term cooling recorded in the Northern Hemisphere.

“…Those studies have explored the mechanisms of environmental evolution (An et al, 2008;Zhao et al, 2008;Hartman and Wünnemann, 2009;Ning et al, 2019). However, detailed reconstructions of the desert environment have been quite limited, partly due to the poor preservation of biotic proxies and the complexity of the regional environment (Dong et al, 2010;Li et al, 2017;Gao et al, 2020). There are still some uncertainties in the study of some characteristics of climate stages in environmental reconstruction, which are worthy of further systematic and thorough investigation.…”

“…Because quantitative temperature reconstructions in this area are very scarce, it is essential to find temperature records for Holocene climate change research in the desert hinterland of the Asian monsoon margin area (Gao et al, 2020). By comparing, checking, and synthesizing a variety of alternative data, some temperature series that can be used to reflect regional and global scales have been reconstructed (Yang et al, 2002;Mann and Jones, 2003;Ge et al, 2005;Moberg et al, 2006).…”

“…Because the formation of phytoliths is deeply affected by environmental factors, they can be used as a good proxy for local vegetation, climate, and environmental conditions. Phytoliths can be well preserved in lacustrine deposits, peat deposits, paleosol strata or even sand dunes (Horrocks et al, 2000;Lu et al, 2007;Zhang et al, 2008;Gao et al, 2020). Moreover, they are poorly transported, relatively easily preserved, and can better reflect primary deposition, while maintaining a clear significance in terms of classification (Lu and Liu, 2003;Gao et al, 2018a).…”

“…Phytoliths are widely used in the study of paleoenvironmental evolution. In China, researchers have undertaken various types of phytolith analyses, using phytolith assemblages, phytolith indices, and phytolith climate factor conversion functions to reconstruct the paleoclimate semi-quantitatively and quantitatively (Qiao et al, 2010;Gao et al, 2018b;Wang et al, 2019;Gao et al, 2020). Accordingly, phytoliths have been recognized as effective proxy indicators of climate change and have been widely used in paleoenvironment evolution research.…”

Quantitative reconstruction of regional paleotemperature is the key to understanding temperature change and its driving mechanisms. In this study, 133 phytolith samples were collected as proxy indicators from lacustrine sediments of the Zhunzhahanjilin (ZZH) profile in the hinterland of the Badain Jaran Desert, China. The phytolith samples were then analyzed to quantitatively reconstruct the Holocene paleotemperature at the millennial scale. Based on accelerator mass spectrometry (AMS), 14C dates and an ordered clustering method were used to divide the phytoliths into five assemblage zones with environmental significance. The quantitative reconstruction results indicated that the paleotemperature in the Badain Jaran Desert was relatively high during the early Holocene (11,040–8,200 cal a BP), and the average paleotemperature was approximately 9.5°C. This may have led to increased melt water near the surrounding area and recharged the lakes in the Badain Jaran Desert, resulting in the expansion of the lakes during the early Holocene. The average paleotemperature during the middle Holocene (8,200–3,100 cal a BP) was approximately 7.9°C. This period was warm and the environment was humid, with extensive precipitation from summer monsoons and low evaporation leading to higher water levels in the lakes. The paleotemperature decreased during the late Holocene (3,100 cal a BP to the present), and lakes retreated or dried up because of the decreased summer monsoon rains. The Holocene paleotemperature in the Badain Jaran Desert may have been related to July insolation in the Northern Hemisphere and had a range of impacts on the hydrological cycle in this arid region.
