A pollen record from Huguangyan Maar Lake documents regional palaeovegetation and palaeoclimate changes in southern China over the last 30 000 years. Huguangyan Maar Lake is located close to the South China Sea (SCS) coastline and is influenced by the East Asian Monsoon (EAM). The pollen assemblages show a succession of vegetation and climate changes. During the Last Glaciation, 30–15.8 cal. ka BP, the Huguangyan area was dominated by subtropical evergreen‐deciduous forest with grassland surrounding the lake, indicating a colder and drier climate than today. During 15.8–11 cal. ka BP, the study area experienced several climatic fluctuations. From 11 to 2 cal. ka BP, the climate shifted to warmer and wetter conditions. After the Holocene Optimum in the early Holocene, the temperature and precipitation decreased. The sediment record of the last 2000 years cannot be used to interpret natural palaeoclimate changes due to the intense anthropogenic influences. Overall, however, the Huguangyan pollen archive highlights the rapid responses of subtropical vegetation to insolation changes in southern China.

“…However, taking the enclosed nature of Huguangyan Maar Lake into consideration, low lake levels tend to provide a favourable environment for Pediastrum because lake water remains in the basin instead of flowing out during low lake level stages (Wu et al . ).…”

“…In south‐western China, a majority of published studies have not detected any abrupt climatic event during the last deglaciation (Liu et al ., ; Hodell et al ., ; Wang et al ., ). A few studies captured one or two abrupt climatic events (Kramer et al ., ; Wu et al ., ). A recent high‐resolution study by Xiao et al .…”

High-resolution pollen and charcoal records from Qinghai Lake in south-western China are presented. The records reveal variations in vegetation, fire and climate history since 18 500 cal a BP. The results show that seven significant vegetation changes are recorded, which are responses to climate changes and/or fire events. Frequent and intensive fires occurred during the periods 17 900-15 000, 13 000-11 500 and 4280-980 cal a BP, corresponding to relatively dry climatic conditions. Combined with the climatic record from Tiancai Lake, the regional climatic changes since 18 500 cal a BP in western Yunnan Province are reconstructed. Namely, the Heinrich Event 1, the Bølling-Allerød warm period and the Younger Dryas event during the last deglaciation are ubiquitous in western Yunnan Province. The start of the Holocene is recorded at 11 500 cal a BP. The Holocene climatic optimum occurred between 8450 and 4280 cal a BP. After 4280 cal a BP, the climate deteriorated, accompanied by evidence for human impact. Based on this study, we consider that vegetation and climatic changes since 18 500 cal a BP in south-western Yunnan Province are primarily driven by September and average summer solar insolation, with some associated influence from regional sea-surface temperature and sealevel rise.

“…Records of the proportion of the >30 lm grain-size fraction from Xingyun Lake, Southwest China, also record the H1, H2, and H3 events (Wu et al, 2015). Four cold events, referred to here as BX0, BX1, BX2, and BX3, can be identified from the K/Rb ratio time series of the Baoxiu peat, and these roughly correspond to the YD, H1, H2, and H3 events, respectively (Bond et al, 1997).…”
