Fig. 4 Variations in hydrological conditions inferred from peat-containing profiles since the LD, and selected environmental proxies. (a) Synthesis of reconstructed Holocene temperature in China [Fang and Hou, 2011]. (b) Annual mean temperature record based on pollen analysis from the Dajiuhu, Shennongjia peat section [Zhu et al., 2008]. (c) Annual precipitation record from Gonghai Lake, Northern China [Chen et al., 2015]. (d) Monsoonal precipitation record from the Daihai Lake region [Peng et al., 2005]. (e) Summer monsoon index reconstructed from the sediments of Qinghai Lake [An et al., 2012]. (f) Dongge Cave stalagmite D4 oxygen isotope record [Dykoski et al., 2005]. (g) Relative Holocene water level variations from the DSGL section in the Southeastern Mu Us Desert [Liu et al., 2017a]. (h) Northern Hemisphere summer insolation at 30°N [Berger and Loutre, 1991]. (i) Synthesis of variations in hydrological conditions inferred from peat-containing profiles (this study).
