基于若尔盖高原湿地唐克剖面孢粉记录的古气候重建北大核心CSCD

对青藏高原东北部若尔盖高原湿地唐克泥炭剖面TK1采样点按10cm间距作孢粉分析,依据主要孢粉类型的百分比关系,以及加速器质谱(AMS)14C测年数据,将剖面孢粉组合大致分为上下两个带。在下带,莎草科均在65%—75%之间变化,表明了相当稳定的气候条件。结合若尔盖表土孢粉数据和唐克泥炭剖面孢粉数据,首次定量重建了唐克7940cal.aBP以来的古气候变化规律:7940—6420cal.aBP,年均温0.72—1.48℃,年降水量650.34—662.29mm;6420—3790cal.aBP,年均温0.56—1.62℃,年降水量647.79—662.34mm;3790—1580cal.aBP,年均温0.54—1.65℃,年降水量647.40—657.71mm;1580cal.aBP至现在,年均温1.45—1.73℃,年降水量661.86—666.41mm。相应于气候变化,沼泽发育也依次经历了4个时期变化,即沼泽化过程发展期—沼泽大发展期—沼泽发育波动期—沼泽再度大发展期。
