Abstract:

在石羊河终端湖猪野泽全新世探井剖面,对连续不同间距368组和74组样品,进行粒度测量与花粉分析.结果表明,沉积物不同粒度敏感组分与典型花粉组合有很好的相关性.花粉总浓度及麻黄(Ephedra)、白刺(Nitraria)、藜科(Che-nopodiaceae)、香蒲属(Typha)、云杉属(Picea)的花粉百分比与小于89.3lμm三个粒度范围的敏感组分存在正相关关系,与大于89.31μm两个粒度范围的组分存在负相关关系.桦木(Betula)、栎(Quercus)、荨麻属(Urtica)的花粉百分比与大于89.31μm三种粒度敏感组分存在明显正相关关系.沉积物花粉组合与粒度敏感组分之间相关关系,主要受控于流域水分条件及相应的湖泊水位,同时也受到流域风沙活动的影响.沉积物中与细颗粒组分正相关关系的花粉指标,主要受到较好的流域水动力条件和高湖面的影响;而与粗颗粒正相关的花粉指标,则与低湖面及风沙作用有关.当流域水分较好,终端湖水位较高的时期,总花粉浓度及河流传播的花粉百分含量较高;流域气候较干燥时期,总花粉浓度较低,风媒花粉的百分含量较高.最后,本文结合猪野泽湖泊沉积物粒度敏感组分与花粉组合的关系,将猪野泽地Ⅸ晚冰期以来的气候、环境变化过程分为6个阶段,其中早、中全新世气候较湿润,晚冰期及晚全新世期间气候相对较干燥。
