Abstract:

测定了新疆罗布泊地区湖相沉积物CK-2钻孔样品的总有机碳含量(TOC)及其同位素组成、碳酸盐含量和C/N比值等环境代用指标,以及石膏矿物的质谱-铀系年龄。测试结果表明,20~9kaB.P.期间沉积物δ13Corg.在-23.4‰~-16.1‰之间波动且阶段性明显,与TOC呈现良好的相关关系,整体变化趋势同南极DomeC冰芯中记录的全球大气CO2浓度一致;C/N比值表明有机碳来源主要是陆生高等植物。因此大气CO2浓度变化是影响20~9kaB.P.期间罗布泊湖相沉积物δ13Corg.值变化的主导因素,周围山体上C3/C4植物相对生物量的变化则是另一重要因素。依据δ13Corg.的变化序列将此时间段湖区古环境的演化分成6个阶段:20.0~14.1kaB.P.期间受到末次盛冰期的影响,气温偏低,湖水丰沛;14.1~13.3kaB.P.是一个气候不稳定期,冷暖波动较频繁,但以暖为趋势;13.3~12.8kaB.P.期间经历了一段冷期,于12.8kaB.P.结束了末次冰期,随后气候开始转暖至11.8kaB.P.;其后气温再次变冷并维持到10kaB.P.;最后从10kaB.P.进入全新世暖期。δ13Corg.序列明显向偏负方向变化,表明该地区变暖的趋势相当明显。罗布泊地区日益干旱化是全球气候变化的结果,尤其是受到全球CO2浓度的不断升高所制约。
