摘要：
选取泥河湾盆地郝家台、小长梁和东谷坨三个典型剖面顶部的黄土沉积进行磁化率和粒度特征的研究，以期揭示盆地晚更新世以来的古地理状况。结果表明，黄土沉积可以划分为S1、L1和S0三层，与我国西北地区典型剖面的黄土堆积和深海氧同位素阶段MIS1-MIS5可以很好的对比。它记录了这一地区130Ka.B.P.以来至少千年尺度的气候和环境变化历史，也说明这一地区对东亚季风气候的变化是十分敏感的。剖面黄土沉积说明盆地在更新世晚期的发育具有差异性，由于断块抬升作用使盆地西部继续接受湖相沉积，而东部则湖盆消失，接受黄土堆积。这些初步成果对研究盆地晚更新世时期的演化具有重要意义。
Abstract:
Based on the study of the characteristics of magnetic susceptibility and grain-size of the loess on the top of some typical sections including Haojiatai(HJT), Xiaochangliang(XCHL) and Donggutuo(DGT) in the Nihewan basin, we try to demonstrate the palaeogeographic status of the basin from the Late Pleistocene. The results indicated that the loess can be divided into three layers: S1, L1, and S0, which have the perfect correlation with those in the Loess Plateau of China and the marine oxygen isotope stage MIS1~MIS5. It recorded the short-term variations of climatic and environmental evolution over the last 130 ka. of North China. Loess of these sections shows the diversity of evolution of the basin. The uplift of the eastern part of the basin due to faulting made the lake vanish and loess was deposited, however, the western part of the basin was still lake during this period.
