Records of the shallow layer profiler in the comprehensive survey of the South Yellow Sea in 1993 and regional drilling bores and cores data were used in this work which studied the shelf shallow stratum depositional structure of the Holocene and late Pleistocene, identified the paleogeomorphic and sediment types at that time, and revealed the paleogeomorphic features of the South Yellow Sea shelf in the last stage of late Pleistocene. The records of the shallow layer profiler showed that the desertized area was characterized by widespread buried dune, aeolian nonclined sandy texture, aeolian depression and platform. The different shelf desertizational sediment types can be divided into aeolian sandy sediments, and mixed accumulation and aeolian dust deposits around the desertization area. The research results indicated that the South Yellow Sea shelf underwent desertication under the cold-dry climatic conditions in the last stage of late Pleistocene and formed a series of the aeolian landforms and sediments.
