黄土与古季风

LOESS AND PALEOMONSOONS

中国黄土的古季风记录研究，揭示了东亚季风区的环境变迁历史是来自中、高纬大陆的偏北冬季风与来自中、低纬海洋的偏南夏季风的环境效应优势期相互交替的历史。文中简要介绍了有关黄土高原黄土与古季风研究的重要进展，侧重讨论了中原地区末次冰期高分辨率黄土所记录的冬季风和夏季风变迁的特征，最后就今后全球变化计划中的黄土与古季风研究提出了几点意见。

The research results on paleomonsoon records of Chinese loess have revealed a history in which the two climatic stages occurred alternately. That is, the East Asian winter monsoon northerly from the mid high latitude continent and summer monsoon southerly from the mid low latitude ocean were respectively characteristic of the two stages and they have dominant effects on environment. There are three parts of content in this paper. The first is a brief introduction to some important research progress of the loess and paleomonsoons on Loess Plateau. The second is a discussion on the winter and summer monsoon variation features recorded by the last glacial high resolution loess in Central Plains. The last, a few pointviews are presented concerning the study of loess and paleomonsoons in the future of global change project in China.
