摘　　要：对密山黑土剖面(0~1.42 m)开展年代学、磁化率、粒度和元素地球化学研究,结果表明,密山市黑土剖面沉积物以粉砂为主,占比约70%;年龄曲线显示密山市黑土的沉积速率为9.62 cm/ka.元素地球化学数据显示,密山黑土剖面的主要常量元素组合特征与其他典型风成堆积物相似,上部陆壳(UCC)标准化曲线的变化趋势基本一致,表明密山黑土成土母质可能为风成成因.多指标综合分析表明,密山黑土剖面自全新世以来的气候变化经历了3个阶段:早全新世的升温变暖、中全新世的温暖湿润和晚全新世降温变凉.The paper studies the geochronology,magnetic susceptibility,particle size and element geochemistry of black soil profile(0-1.42 m)in Mishan City.The results show that the sediments of black soil profile are mainly silt,accounting for about 70%,and the deposition rate of black soil is 9.62 cm/ka according to the age curve.The element geochemical data reveals that the major element combination characteristics of Mishan black soil profile are similar to those of other typical eolian deposits,and the change trend of UCC-normalized curves is basically the same,indicating the parent material of Mishan black soil may be of aeolian origin.The multi-index comprehensive analysis shows that the climate change of Mishan black soil profile since Holocene has experienced three stages,i.e.temperature rising in the Early Holocene,warm and humid in the Middle Holocene and cooling down in the Late Holocene.
