摘要
湖泊沉积物中的孢粉组合是重建古环境的重要手段。猪野泽湖盆地区全新世孢粉组合情况复杂,中全新世孢粉组合差异较大,但已有研究都集中在西湖盆,缺少对东湖盆和整个湖盆不同位置孢粉组合的差异探讨,而湖泊碳酸盐沉积所指示的碱性环境又影响着花粉的保存,从而影响着孢粉组合。
     本文通过研究湖泊沉积物中碳酸盐含量与孢粉的保存关系,探讨了该区域花粉保存是否受到过盐湖沉积的影响,以及花粉组合的差异是否与花粉保存有关。在此基础上,重建了猪野泽东湖盆SKJ和JTL剖面的全新世孢粉组合,对比了中全新世整个湖盆孢粉组合差异。结果表明,在猪野泽全新世两个成湖期,很多碳酸盐含量较高的层位,花粉浓度也较高。虽然高碳酸盐含量对应的强碱性环境对孢粉的腐蚀性大,但当时猪野泽成湖期内气候温暖湿润,孢粉输入量非常大,以至于碱性沉积环境不足以改变孢粉的浓度,因此花粉保存状况不受湖泊碱性条件的制约。东湖盆的湖岸和中心区孢粉组合一致性较高,而西湖盆的SJC剖面孢粉组合与QTH02、QTL-03剖面差异较大;同时,东、西湖盆孢粉组合也存在孢粉类型差异。造成这种差异的主要原因是西湖盆入湖区受水动力条件影响较大,孢粉组合受全流域植被类型影响,而东湖盆主要保存风力带来的本地区花粉,沉积环境稳定,孢粉组合可正确反映猪野泽地区中全新世环境状况。因此,湖水扰动和波浪导致的沉积物再沉积现象可以造成湖盆不同位置孢粉组合的差异。
Pollen in lake sediments is an important proxy for reconstructing the paleo-environment. In Zhuye Lake, northwest China, the Holocene pollen records indicate variable environmental histories in different locations of the lake basin. Previous studies focused on the western lake basin, in the east part of the lake basin, the pollen assemblages were less reported. Lake carbonate sediments can show alkaline sedimentary environment, while alkaline environment has serious corrosion on pollen affecting pollen conserving.
     According to the relationship between carbonate and pollen concentration in lake sediments, we can explore whether the regional pollen conserving was affected by carbonate.In this research, we analyzed the pollen assemblages of the SKJ and JTL sections in the east part of the basin for conducting a comparative study of the pollen assemblages in the entire lake basin during the mid-Holocene. The result has showed that the high carbonate content and the high pollen concentration corresponded with each other in Zhuye Lake during the Holocene. The climate was warm and wet in Zhuye Lake during the period of lake expansion, while there is a large amount of pollen input, although alkaline environment has serious corrosion on pollen conserving. Therefore, the alkaline sedimentary environment was not enough to change the pollen concentration. The different mid-Holocene pollen assemblages in different location of the lake basin were not resulted by the pollen conserving. The results showed that the pollen assemblages were similar between the shores of the eastern lake basin and the central lake area, while the pollen assemblages of the SJC section were different from those of the QTH02and QTL-03sections. There were also disparities in pollen types between the eastern and western lake areas. The main reasons for these differences are as follows:the west-lake area was greatly influenced by the hydrodynamic conditions, and the pollen assemblage was affected by basin-wide vegetation types. The pollen assemblage for the eastern part mainly came from local and transported by wind; the sedimentary environment is relatively stable; therefore, the pollen assemblages there can reflect the mid-Holocene environment in Zhuye Lake, not for the entire drainage basin. Totally, sedimentary re-deposition effects caused by water disturbance and lake water waves are the main dynamic reasons for the different pollen records in the lake basin.
