| 摘 要： | 对山东半岛北部蓬莱林格庄黄土剖面进行了系统的野外考察,并进行了光释光测年以及粒度、磁化率指标分析。研究表明,磁化率的变化与不同粒级的百分含量具有一定的相关性,频率磁化率与粗颗粒含量基本呈一定的负相关。结合野外地层划分与光释光年代学测试可以将该剖面划分为3个黄土层和3个古土壤层,该剖面记录了末次间冰期以来该区气候和环境变化的历史。

| Abstract: | Chinese loess-paleosol sequence has provided detailed terrestrial records of climate change during the Quaternary. Field work was carried out systematically on one loess section at Lingezhuang of Penglai in northern Shandong Peninsula, and optically stimulated luminescence(OSL )dating, grain size and magnetic susceptibility measuring were conducted. The results show that there are three types of grain size frequency curves, and environment-sensitive size fractions of this section are 22.39~25.12 μm and 56.23~63.10 μm. Changes of magnetic susceptibility and percentage of the different size fraction are correlated, and there is a negative correlation between frequency magnetic susceptibility and coarse particle contents. The section is divided into three loess layers and three paleosol layers, which record the information of climatic change and environmental evolution over the last interglacial stage. |
