Although the temperatures during the winters in the south are not as low as in the north…those who have been to Nanjing before can definitely understand that kind of wet cold…so this kind of winter is very uncomfortable…and I pretty much get chilblains every year….

师大, 同学,致敬作者:随风南方冬天的气温虽没有北方那么低。。。但是来过南京的必定能体会到那种湿冷。。。。而且南方没有供暖。。。。所以这样的冬天很是难受。。。几乎年年生冻疮。。。。

From 6860 to 3170 cal.yr BP,semi-desert steppeexpanded,regional montane forest steppe retreated,suggesting a prolonged warm and dryclimate.Between 3170 and 2340 cal.yr BP,regional forest steppe expanded whereassemi-desert steppe retreated,indicating the climate became cool and wet gradually and thehumidity reached the maximum at the end of this stage.During 2340~1600 cal.yr BP,Poaceae steppe dominated whereas wetland meadow expanded and the montane forest stepperetreated,suggesting a cool and wet climate prevailed,wormwood grass steppe prevailed andthe climatic instability increased after 1600 cal.a BEThe climate and environmental reconstructions by pollen were supported by the diatomrecords.A relative high lake level and moister climate prevailed between 8660 and 7230 cal.yr BP as inferred by the dominance of planktonic diatom genera and high planktonic/benthicratio (〉40).low lake level and dry climate sustained during 7230~2330 cal.yr BP assuggested by the low abundance of planktonic diatom and low planktonic/benthic ratio ~20and the lake returned to high level during 2330~930 cal.yr BP as inferred by there-dominance of the planktonic diatom and the high value of palnktonic/benthic ratio.The pollen-based climate reconstruction was also consolidated by the grain size andPediastrum concentration records.
