晚第三纪以来黄土高原完整连续、高分辨率的风尘堆积序列为研究以冬、夏季风组合为特征的东亚季风环流长期演化提供了很好的气候信息载体。利用高压固结试验结果，基于高分辨申的磁化率和容重测量及相关性分析，初步探讨了黄土、古土壤及红粘土不同地层单元的压缩特性，校正了压实作用对容重的影响，获得了更真实的东亚季风气候演化信息。有助于深入探讨晚第三纪以未东亚李凤阶段性演化特征及其与太阳辐射、全球冰量变化、青藏高原阶段性隆升等气候控制因子之间的密切关系。
Since the Late Tertiary, the complete and continuous high-resolution dust deposition sequence on the Loess Plateau has provided a good carrier of climate information for studying the long-term evolution of the East Asian monsoon circulation characterized by winter and summer monsoon assemblages. Based on the results of high-pressure consolidation test, based on the high-resolution magnetic susceptibility and bulk density measurement and correlation analysis, the compression characteristics of different formation units of loess, paleosol and red clay were preliminary discussed, and the influence of compaction on bulk density was obtained. A more realistic East Asian monsoon climate evolution information. Which will be helpful for the in-depth discussion on the relationship between the staged evolution of Li Feng and the climatic control factors in the Late Paleozoic, such as solar radiation, global ice volume change, and stage uplift of the Qinghai-Tibet Plateau.
