在对中国陆架古环境研究的基础上,提出晚更新世末期陆架沙漠化的定义、形成的环境背景及其演化过程.通过对海底浅地层剖面仪的测量记录以及钻孔分析资料的研究表明,低海面时出露的陆架平原以干冷的风砂沉积为主,在强劲的古冬季风的作用下,部分出露的海相地层发生解体,发育成沙丘,出现沙漠化环境;细颗粒被吹扬,并在下风头形成衍生沉积。
Based on the study of the paleosol in the continental shelf in China, the definition of the shelf-desertification, the environmental background and the evolution process of the shelf-desertification at the end of the Late Pleistocene are put forward. Based on the surveys and records of shallow subterranean profile meters and borehole analysis data, The exposed continental shelf on the sea surface is dominated by dry and cold wind sand. Under the action of the strong ancient winter monsoon, some of the exposed marine strata disintegrated and developed into sand dunes with desertification. Fine particles were blown, And lead to the formation of derivative deposition.
