【摘要】 综合论述了全新世大暖期环境的主要特征:降水量增加,气温上升,植被带北移西迁;肯定了大暖期中存在的低温干旱事件,大暖期也不是持续稳定的温暖湿润期.根据太阳14C丰度与中国西部祁连山敦德冰芯δ18O、德国南部Ammersee深海平原δ18O的对比,显示全新世气候的变化可能同太阳活动有密切关系;用REDFIT35对大气剩余14C与EIK湖泊沉积记录作频率对比分析显示,试图证明在9～3kaB.P.期间气候变化存在千年尺度周期波动的可能性.更多还原

【Abstract】 The general character of the Holocene Hypsithermal is described synthetically: precipitation increase, temperature rise, vegetation move to the north and the west. It is agreed that there are also cool and drought cases existing and not always warm and wet during the Holocene Hypsithermal. Base on the contrast among the Residual ¹⁴C, δ¹⁸O in north German Ammersee Abyssal plain, δ¹⁸O in the DunDe ice-core, It is confered that there maybe the close relation between the variety of the climate and the solar activity in Holocene,and then a contrast between Residual ¹⁴C and ELK Lake pollen frequency by REDFIT35 is given, just trying to test the possibility of thousands or hundreds years’ periodic fluctuation during the 9～3 ka B.P..更多还原
