摘要: 黄土在中国沉积广泛，是研究气候与环境变化的良好载体。本文对位于黄土高原东南缘的扣马黄土展开研究，使用CM-700D型分光测色计测量了908个黄土–古土壤样品的色度。研究表明，1.2 Ma以来，黄土高原东南缘气候整体呈冷干化趋势，很大程度上受到全球气候变化的影响。同时，自0.25 Ma以来，可能受到近源黄河河漫滩物质影响，扣马黄土的色度和磁化率指标都发生了很大变化。扣马的黄土–古土壤序列沉积，很可能受到全球气候与沉积环境变化的双重影响。
Abstract: Loess is widely deposited in China and is a good carrier for studying climate and environmental changes. This article conducts research on the Kouma loess located on the southeastern edge of the Loess Plateau. 908 loess samples were measured using CM-700D spectrophotometer and Bartington MS2C magnetometer, respectively. Research has shown that since 1.2 Ma, the climate in the southeastern margin of the Loess Plateau has shown an overall trend of cooling and drying, influenced by global climate change. Meanwhile, since 0.25 Ma, significant changes have occurred in the chromaticity and magnetic susceptibility indicators of the Kouma loess due to the influence of materials from nearby river floodplains. The sedimentation of the loess paleosol sequence in Kouma may be influenced by both global climate change and changes in sedimentary environments.
