长春腰分水岭黄土剖面常量化学元素特征及其气候意义

长春腰分水岭中更新世晚期黄土剖面的野外观察和常量化学元素分析结果表明：各层中常量化学元素的规律性变化不仅能够揭示出剖面沉积时气候干冷－湿暖的多次波动，而且与野外各层的宏观特征具有良好的对应性；该项研究对于恢复中更新世晚期古气候及其变化具有重要意义，也为松辽平原东部第四纪地层的划分与对比提供了重要证据。

Geochemical Characters of Invariable Elements in Yaofenshuiling Loess Profile and Its Significance of Climate

Field observation and invariable elements analysis are made in the late middle Pleistocene loess section of Yaofenshuiling. The results show that the variation of invariable elements in all layers not only can show climatic fluctuations of dry and cold-wet and warm in the formation of the loess section, but also corresponds to the macroscopical characteristic of field layers. This research is important to restore the paleoclimate and its changes in the region where the section is located, and it is also an important proof for the Quaternary strata division and contrast in the east of Songliao plain.
