根据黄、渤、东海的浅地层剖面仪记录,作者发现晚更新世末期中国黄、渤、东海陆架曾发生过沙漠化。据目前所知,渤海的辽东浅滩、黄海的苏北浅滩、东海的台湾浅滩,都可能为独立的沙漠体,全新世海侵后将其淹没。衍生沉积可划分为3种类型,其一为完全埋藏型,构成南黄海北部的厚层泥质沉积区;其二为半埋藏性,如庙岛列岛一带的黄土沉积;其三为完全出露型,以南京附近的黄土沉积为典型。古季风的吹扬作用是海退后陆架发生沙漠化和产生一系列衍生沉积的基本动力。
According to the records of shallow stratigraphic records in the Yellow Sea, Bohai Sea and East China Sea, the authors found that desertification occurred on the shelf of China Yellow Sea, Bohai Sea and East China Sea at the end of Late Pleistocene. As far as we know, the Liaodong shoal in the Bohai Sea, the shoal of North Jiangsu in the Yellow Sea, and the shoal of Taiwan in the East China Sea are all likely to be independent desert bodies that were submerged after the transgression of the Holocene. Derived sediments can be divided into three types, one of which is fully burial type, forming a thick muddy sedimentary area in the northern part of the southern Yellow Sea; the second is semi-burial, such as loess sediments in the island of Miaodao; the third is completely exposed Type, to loess deposits near Nanjing as a typical. The blowing effect of the ancient monsoon is the basic driving force for the desertification of the shelf and a series of derivative sediments after the coastline retreat.
