“…Given that the Greater Khingan Mountains region may have been covered by thick snow during the last deglaciation (Pang et al, 2021), the snow/ice meltwater from the surrounding mountains, generated in response to the persistent warming in the EASM margin induced by the high Northern Hemisphere summer insolation during the early Holocene, may have made an important contribution to the lake level change in Dali Lake. This inference is supported by other studies (Fan et al, 2019; Li et al, 1990; Xiao et al, 2008; Yue et al, 2021). In addition, the low lake water temperature caused by the cold meltwater influx during the early Holocene (Yue et al, 2021) may also have reduced the evaporation of the lake water.…”

“…However, there is an ongoing and vigorous debate about whether the Holocene highest water level of Dali Lake, in northern China, occurred in the early Holocene (11.7-8.0 ka) or the mid-Holocene (8.0-4.0 ka) (Goldsmith et al, 2017a(Goldsmith et al, , 2017bJiang et al, 2020;Liu et al, 2017a). It is also disputed whether replenishment of the lake water by snow/ice meltwater from the Great Khingan Mountains affected the level of Dali Lake during the early Holocene (Fan et al, 2017(Fan et al, , 2019Goldsmith et al, 2017aGoldsmith et al, , 2017bJiang et al, 2020;Liu et al, 2017a;Xiao et al, 2008Xiao et al, , 2009Yue et al, 2021). Although the history and the factors driving the lake level changes of Dali Lake have been of major scientific interest for several years, the lack of a resolution of these issues has led to much controversy about whether the Holocene EASM maximum occurred in the early Holocene or the mid-Holocene (Goldsmith et al, 2017a(Goldsmith et al, , 2017bJiang et al, 2020;Liu et al, 2017a;Xiao et al, 2008).…”

Lake level evidence for a mid-Holocene East Asian summer monsoon maximum and the impact of an abrupt late-Holocene drought event on prehistoric cultures in north-central China

Uncertainty regarding the timing of the highest Holocene water level of enclosed Dali Lake in northern China has led to controversy about whether the East Asian summer monsoon (EASM) peaked in the early Holocene or the mid-Holocene. Therefore, a record combining a reliable chronology with unambiguous lake level indicators is essential to resolve the issue. In this study, we established a temporal sequence of well-preserved paleolake shorelines at different elevations around Dali Lake using quartz optically stimulated luminescence (OSL) dating. Combining the new OSL-based chronological data with the previously published ages of beach ridges, we constructed an integrated lake level record for Dali Lake since the last deglaciation; the record is chronologically well-constrained and provides a clearer representation of lake level changes than previous studies. The main findings are as follows: (1) the level of Dali Lake rose gradually during 14.5–8.0 ka and reached a highest level during 8.0–6.0 ka that was ~61 m higher than today, before gradually declining after ~6.0 ka; (2) although the short-lived highstand of Dali Lake during the early Holocene was caused by both monsoon precipitation and snow/ice meltwater influx, the mid-Holocene lake level maximum was mainly the result of increased monsoon precipitation. These findings indicate that the EASM maximum in the region occurred during the mid-Holocene, which is supported by precipitation-proxy records from the EASM margin; (3) a major decline (~30 m) of the level of Dali Lake occurred at ~4.2 ka, reflecting a regional-scale drought event in northern China. Combined with near-contemporaneous frequent floods in the lower Yellow River, we propose that the pattern of “drought in northern China, flooding in central China” occurred during ~4.2–3.8 ka, triggering the migration of the prehistoric human population of the area to the central Plain of China. This population migration may have destabilized the existing social order and promoted the emergence of more complex societies, leading to the development of early civilization in north-central China.

“…In this study, the EASM northern boundary is defined by three metrics. The first is the 400‐mm annual isohyet (hereinafter P 400 ), which is widely accepted as the boundary both between the monsoon and non‐monsoon regions and between forest and steppe vegetation (Fan et al., 2019; Xiao et al., 2018). The second metric depicts the climatological northern boundary by using the 2 mm day −1 isohyet in summer (May‐September; MJJAS) (hereinafter P summer ) (J. Chen et al., 2018).…”

“…In Dali Lake, a significant variation of mineral content indicated dramatically decreased inflowing water and decreased lake levels from 5.9 to 4.8 ka ago. Since 4.8 ka, quartz and albite percentages recovered to higher levels compared with the preceding period of 5.9-4.8 ka, but were much lower than before 5.9 ka, which suggests that drainage losses of lake water were much less from 4.8 to 0 ka than from 5.9 to 4.8 ka [149]. Compared with Dali's relatively large-amplitude oscillation of the hydrographic environment at 5.9-4.8 ka, pollen-derived, reconstructed Pa in Hulun lake declined slightly (fluctuating at around 330 mm at 6.4-4.4 ka) compared to the last stage (around 340 mm); until the period of 4.4-3.3 ka, the lowest Pa of the entire Holocene with an average of 260 mm was registered [115].…”

The Possible Stimulation of the Mid-Holocene Period’s Initial Hydrological Recession on the Development of Neolithic Cultures along the Margin of the East Asian Summer Monsoon

A better understanding of past East Asian summer monsoonal (EASM) variations, which play a key role in the development of the largely rain-watered agriculture in China, could contribute to better appraising potential impacts on EASM with regard to global climate change. However, our knowledge of the relationship between mid-Holocene hydrological recession and the development of Neolithic culture is limited due to a lack of joint studies and a compilation of spatiotemporal data, especially on the episode of ~6–5 ka from the mid-Holocene Optimum (HO) along the peripheral realm of the EASM. Here, we suggest that the hydrological recession between ~6–5 ka, on the basis of lithology and geochemical element analysis, occurred not only in the Horqin sandy land, but also in other fluvial-lacustrine, stalagmitic, loess, and aeolian records across the whole monsoon-influenced boundary belt. These records indicated varied, more or less synchronous, and coherent moisture changes, yet with not entirely consistent onsets, durations, and degrees. We attributed this spatiotemporal complexity to the orbit-induced weakening of summer solar insolation, and the interactions of the Asian monsoon (AM) and westerlies, as well as topography and regional vegetation factors. Furthermore, the mid-Holocene initial hydroclimatic recession during ~6–5 ka within the thresholds of an eco-environment bearing a capacity system, might have facilitated the development of mid–late Neolithic culture and stimulated the north and northwest expansion and integration of region-specific Neolithic culture.
