中国暖温带海岸风尘沉积序列的研究现状与展望

中国暖温带海岸的风尘沉积序列是断续分布于渤海-北黄海沿岸的以黄褐色为主的粉砂质或砂质沉积物。通过查阅1960年以来的文献资料，综述了此类沉积的分布规律、地层形态、沉积特征、地质年代、形成机制和古环境演变等方面的成果，认为其主体为陆架沙漠化环境下的衍生沉积，是冬季风搬运近源物质的结果，时代上属中-晚更新世。因此，暖温带海岸风尘沉积序列是渤海-北黄海陆架沙漠化的有力佐证，且较好地记录了中国中更新世以来中纬度沿海地区的气候环境变化：时间上，气候逐渐干冷；空间上，自北向南风化作用增强。基于研究现状，展望了今后的工作重点和方向。

Overview and Prospect of Research on Eolian Deposits Sequence along the Warm Temperate Coast of China

The eolian deposits sequence on the warm temperate coast is a kind of silty or sandy sediment with the color of yellow-brown, and is mainly distributed discretely along the Bohai Sea-North Yellow Sea coast of China. In this paper, the spatial distribution, forms, sedimentary characteristics, formation mechanism, geological age, and paleoenvironment of eolian deposits sequence are overviewed. Eolian deposits sequence is derivative sediment of shelf desertification. Its main source is the near source material transported by the winter wind, and it originated in the Middle-late Pleistocene. The coastal eolian deposits sequence powerfully proves the theory of shelf desertification, and records the climate change in the mid-latitude coastal areas of China since the Middle Pleistocene in detail. The climate is gradually dry and cold, and the weathering from north to south is gradually enhanced. Based on the present situation of the research, there are still some issues need to be deeply discussed.
