摘要

摘要: 孢粉提取方法是第四纪孢粉学研究的基础和前提，中国北方地区具有独特的自然地理条件，第四纪以来形成了特有的沉积物类型，不同沉积物的孢粉提取研究一直以来是中国孢粉学研究的难点和热点。本文选取了中国北方不同沉积相的沉积物样品（黄土与古土壤样品17个、湖泊样品沉积物20个、风成砂样品11个、泥炭沼泽样品10、考古点文化层6个、表土样品10个）共74个，通过对同一种样品不同处理方法的对比研究，就中国北方不同沉积物的孢粉提取方法进行了探讨。对比研究发现，黄土及古土壤中的孢粉提取是以氢氟酸筛选法效果佳，值得注意的是盐酸与氢氟酸对样品的处理过程，进行多次彻底处理才能达到很好的效果；湖泊沉积物孢粉提取可采用传统的氢氟酸法，对干旱区含砂量较高的湖泊沉积物及风成砂样品需要配合重液浮选法进行；泥炭、沼泽中孢粉提取应采用重液浮选法，配合筛选法进行；考古点文化层沉积物孢粉提取应采用重液浮选法，并将重液浮选出来的样品配合以氢氟酸处理能达到很好效果；表土样品可以采用无酸碱重液浮选法。同时还探讨了孢粉提取中的分散剂和硝酸的使用及酸碱的使用顺序。

Abstract: The extraction methods of Quaternary pollen and spores are the bases and precondition in Quaternary Palynology. Northern China is in particular physical geography environment. In Quaternary there are many different types of sediments in northern China. And at all times extraction methods of Quaternary pollen and spores from different type of sediments are the difficulties and highlights in North China. In this paper we choose 74 sediment samples which are from different types of sediment (Loesspaleosol sequence sediment samples, lake sediment samples, Aeolian sand samples, peat and bog samples, Archaeological samples and surface samples). Through our investigations in the laboratory, we have some conclusion about the extraction methods of Quaternary pollen and spores from different type of sediments. To the Loesspaleosol sequence sediment samples the HF treatment and sievinganalysis methods are effective, to be attention is the HF and HCl treatment are needed to be treated more times, and very time of treatment is need to wash to neutral. To lake sediments the HF treatment method is effective, but in North China there are many lakes in the arid area to these samples from arid lakes after HF treatment we should take another step which is heavy liquid methods. To Aeolian sand samples the HF treatment method and heavy liquid method are also effective. To peat and bog samples the heavy liquid method is effective, but some samples of the peat and bog after heavy liquid method we need use the sievinganalysis method to reduce impurity. To the archaeological samples, the first step is heavy liquid method and after that it is better to use the HF treatment method. To surface samples acidalkalifree analysis is the best choice. In the end we discussed the use of the dispersant and HNO3 and the using sequence of acid and alkali.
