“…These findings are supported by the highest tree pollen content found in sediment from Daihai Lake (Xiao et al., 2004), Dali Lake (Wen et al., 2017; Figure 8n) and Bayanchagan Lake (W. Jiang et al., 2019) for this period (Figure 1). A recent study from Lake Chagan Nur in marginal zone of the EASM in northern China also shows that monsoon precipitation reached a maximum in the mid‐Holocene, around 8–6 ka, when it was 30%–50% higher than at present (G. Li, Wang, et al., 2020). During this period, significantly enhanced monsoon precipitation led to extensive paleosol development in both the desert—loess transition zone (e.g., in the Jingbian region) (Xiao et al., 2002) and the interior of the Mu Us Desert (e.g., in the Yulin region) (H. Lu et al., 2013).…”

The East Asian Summer Monsoon (EASM) drives the distribution of heat and water vapor in east Asia, and has been linked to the survival of billions of people in the region (An et al., 2012; Chen et al., 2015). Understanding the dynamics and variability of the EASM since the Holocene is crucial for understanding current global warming, and for accurate prediction of future climate change. As a transition region between monsoon and arid inland climates, the modern monsoon marginal zone has a semi-arid to semi-humid climate, which is highly sensitive to global climate change and to the EASM response to the changes. There are abundant geological archives in the monsoon marginal zone containing information about the evolution of the EASM (Figure 1a) (

“…The contribution of cosmic ray was calculated using the buried depth of the samples, altitude, and geomagnetic latitude following the reference (Prescott and Hutton, 1994). Based on the local deposited environment, previous research (Li et al, 2020a), and measured and saturated water content of these samples, the water content of 10 ± 5% was assumed in the aging calculation. The total dose rates were finally calculated using the functions defined by Aitken (1985); Aitken (1998).…”

“…Depositional records of Hulun Lake located in northeastern Inner Mongolia demonstrated that Hulun Lake developed a high lake level during the deglacial and early Holocene (Zhang and Wang, 2000), and thereafter, the secondary high lake level developed again during the mid-Holocene (Liu et al, 2016). Reconstructed lake-level fluctuations in Chagan Nur, an enclosed lake located in eastern Inner Mongolia at the fringe of the modern EASM region, showed a lake highstand of 15-12 m higher than that present at 11-5 ka, with a maximum precipitation of 30-50% higher than that present at 8-6 ka (Li et al, 2020a). Similarly, the depositional records of Juyanze and Zhuyeze terminal lakes on the Alashan Plateau in western Mongolian plateau indicated that the high lake level developed in the early Holocene and gradually disintegrated at 7-5 Cal.…”

“…There are large numbers of inland enclosed lakes near the East Asian monsoon margin of China which are highly sensitive to climate change due to its unique regional characteristics. Thus, their lake-level fluctuations are the most direct indicators of regional precipitation and moisture variability related to the intensity of monsoon activities and climate change (Liu et al, 2015;Li et al, 2020a). However, increasing high-resolution lacustrine deposit records have revealed that the lake-level fluctuations during the early and mid-Holocene in East Asian monsoon marginal regions were quite different; especially, the timing of the high lake level in different lakes was asynchronous, and even the same lake might be distinct based on the different dating methods or different materials and proxies.…”

Lake-level reconstruction of inland enclosed lakes especially for monsoon-sensitive areas is of great significance to reveal regional climate changes. Daihai, a typical enclosed lake at the marginal of the East Asian summer monsoon (EASM) area in north China, is sensitive to climate changes due to its unique regional characteristics. There were a series of lakeshore terraces, highstand lacustrine sediments, and braided river deltas, providing sufficient geomorphologic and stratigraphic evidence for the reconstruction of lake-level fluctuations of Daihai. Reconstructed lake-level variations during the early and mid-Holocene were constructed based on 22 quartz optical stimulated luminescence (OSL) ages from six well-preserved profiles around Daihai Basin. Our results indicated Daihai showed a relatively low level at 10.2 ka, and a gradually increasing lake level following the enhanced monsoon precipitation during the mid-Holocene. Specifically, the high lake level began to develop at 8.1 ka and reached the maximum at 5.2 ka, with ∼40 m higher than present. At this time, the lake area expanded to ∼400 km2, approximately six times as large as that of present, corresponding to the maximum monsoon precipitation and intensity of EASM during the mid-Holocene. However, our stratigraphic records showed a part of the depositional records in the north and east of the Daihai was missed after 5.2 ka, probably indicating a sudden drop of the Daihai lake level. These rapid level fluctuations were likely to be interpreted by some local scenarios and need to be further investigated in the future. Overall, the lake-level fluctuation of Daihai during the early and mid-Holocene was slightly different from that observed in the previously published regional records. Possibly, the interaction of the EASM and regional feedback from topography, and hydrology factors might have contributed to the spatial complexity and distinction.

“…The southern Mongolian Plateau located at the margin of EASM is an ideal place to study the mechanism and variation of EASM. The lake sediments in these regions are the ideal carriers to reconstruct the variations of EASM intensity in the past period (Jin et al, 2006;An et al, 2012;Zhang et al, 2016;Goldsmith et al, 2017;Wen et al, 2017;Li et al, 2020;Chen et al, 2021).…”

The lakes at the southern Mongolian Plateau are sensitive to the variation of EASM changes during the Holocene, and hence the lacustrine records of these lakes provide prospects for understanding how lake environmental changes respond to EASM variation at different timescales. The interpretation of proxy indexes of lacustrine sediments is complex due to the various climatic or/and environmental factors influencing the processes during deposition and after deposition. In this study, the elements and colors of an 11.7-m lacustrine record from Chagan Nur at the southern Mongolian Plateau of northern China were analyzed to constrain the lake environmental changes during the Holocene. The results show that stable elements of Al, Si, K, Ti, Fe, and Rb are more related to surface erosion or/and vegetation coverage, and the variation of Sr is related to the lake-level change in Chagan Nur. The element and color of the lacustrine records show that a small and shallow lake environment occurred at Chagan Nur during 11.7–10.5 ka, the lake level had increased during 10.5–7 ka, and then the lake shrank with strength surface erosion during 7–6.2 ka and from 2 ka to the present. The lake level and surface erosion changes of Chagan Nur have shown a direct response to EASM precipitation changes as reconstructed from the pollen record from the Chagan Nur Lake and other records from northern China.
