“…And at least 500 pollen grains were counted for each sample in this study to ensure a statistically adequate and representative sample of observations. Moreover, Zhang et al (2021) suggested that the pollen loading in Daye Lake is predominantly wind-transported, indicating that the palynological diversity reconstructed in this study is representative of the vegetation of the Qinling Mountains region. Nevertheless, several studies have shown that palynological diversity is positively correlated with plant diversity (Odgaard, 1999;Meltsov et al, 2011;Birks et al, 2016a;Felde et al, 2016).…”

“…The regional climate is influenced by the East Asian summer monsoon, and the annual mean air temperature and precipitation are 8.1 • C and 720 mm, respectively. The coldest month (January) and warmest month (July) have respective average temperatures of −4 and 19.3 • C, based on a 30-year meteorological dataset (CE 1981(CE -2010 from Taibai county meteorological station (1,545 m a.s.l) (see Figure 2 in Zhang et al, 2021). Based on the lapse rates for the northern slopes of the Qinling Mountains proposed by Ma et al (2017), the mean annual, January and July temperatures are 2.8, −7.3, and 13.6 • C, respectively.…”

“…Daye Lake is surrounded by alpine shrubland and meadow. The shrub taxa are dominated by Salix cupularis, Rhododendron capitatum, and Spiraea, and the local herb taxa are mainly Ranunculaceae, Brassicaceae, and Poaceae (Zhang et al, 2021).…”

“…The Qinling Mountain range is the natural geographic and climatic boundary between North and South China. The area is influenced mainly by the East Asian summer monsoon and the vegetation is highly sensitive to climate change (Liu et al, 2008;Zhang et al, 2021). Mount Taibai, which is the highest peak in the Qinling Mountain range, has numerous alpine lakes, and the pollen assemblages in the sediments of these lakes are a valuable archive of information on climate change and vegetation succession.…”

Global warming is having a profound influence on vegetation and biodiversity patterns, especially in alpine areas and high latitudes. The Qinling Mountain range is located in the transition zone between the temperate and subtropical ecosystems of central–east China and thus the vegetation of the area is diverse. Understanding the long-term interactions between plant diversity and climate change can potentially provide a reference for future landscape management and biodiversity conservation strategies in the Qinling Mountains region. Here, we use a pollen record from the Holocene sediments of Daye Lake, on Mount Taibai in the Qingling Mountains, to study regional vegetation changes based on biomes reconstruction and diversity analysis. Temperature and precipitation records from sites close to Daye Lake are used to provide environmental background to help determine the vegetation response to climate change. The results indicate that climate change was the main factor influencing vegetation and palynological diversity in the Qinling Mountains during the Holocene. The cold and dry climate at the beginning of the early Holocene (11,700–10,700 cal yr BP) resulted in a low abundance and uneven distribution of regional vegetation types, with the dominance of coniferous forest. During the early Holocene (10,700–7,000 cal yr BP), temperate deciduous broadleaf forest expanded, palynological diversity and evenness increased, indicating that the warm and humid climate promoted vegetation growth. In the middle Holocene (7,000–3,000 cal yr BP), the climate became slightly drier but a relatively warm environment supported the continued increase in palynological diversity. After ∼3,000 cal yr BP, palynological diversity and the evenness index commenced a decreasing trend, in agreement with the decreased temperature and precipitation in the Qinling Mountains. It’s noteworthy that human activity at this time had a potential influence on the vegetation. During the past few centuries, however, palynological diversity has increased along with the global temperature, and therefore it is possible that in the short-term ongoing climatic warming will promote vegetation development and palynological diversity in the area without human interference.

Southeastern China's coastal region is considered one of the key areas for studying prehistoric human–land relationships in the Western Pacific region. This region, which is rich in records of marine civilization, provides an ideal location for recording coastal environmental evolution. In this study, the chronological framework of three borehole cores recovered from Haitan Island, South China, near the Keqiutou group of sites, was established using both optically stimulated luminescence (OSL) and accelerator mass spectrometry radiocarbon (AMS 14C) dating techniques. Various analyses, including lithologic characteristics, chroma, clay–water electric conductivity (EC), grain size and elemental geochemistry, were conducted to elaborate the sedimentary sequence and its paleoenvironmental implications. The findings suggest that (i) since the late Quaternary, the Haitan Island sedimentary sequence can be divided into three deposition stages: Old Red Sand formed during Marine Isotope Stage 3 (MIS3), intermittent sedimentation during the Last Glacial Maximum and coastal aeolian deposition during the Holocene. Furthermore, the study reveals that terrestrial debris was significant as a material source for Haitan Island. (ii) Due to the absence of tectonic uplift, Haitan Island has no thick marine sedimentary record during the Holocene period of high sea level. The Luyangpu coastal sand sheet can be dated to 2.78 ka, which is consistent with previous reports giving dates of 2.4 ka. Prior to the formation of the sand sheet, the sedimentary environment in the area was characterized by lagoon or marsh facies. (iii) Paleoanthropological activities were influenced by sedimentary environmental evolution and geomorphic processes, among others. The Keqiutou Culture experienced high sea levels, which created an intertidal environment near the site and facilitated fishing. However, regression at 5.7 ka led to terrestrial environments, which prompted the inhabitants to migrate. Approximately 3 ka ago, sea levels rose again, coinciding with the initiation of rice cultivation. These factors may have influenced the transition from the Neolithic to Bronze Age culture. This study reconstructs evolution of the sedimentary sequence since the late Quaternary, enhancing our understanding of past human–terrestrial relationship in the region.
