Abstract: In this paper,mainly based on the studies for some time past,the authors summarized the paleoenvironmental features of the coastal region of South China during the full-glacial period of Late Pleistocene.They estimated the difference in the environment conditions between modern a.d LGM as follows.(1) On the average,the winter temperature of the land was lowered 11-15℃ or so.(2) The paleochannel bottom reached a depth of -62m or so at the present debouch of the Zhujiang delta,(3) The paleo-coastline was situated at 150m or so below the present sea-level.(4) The February temperature of the upper water in the northern part of South China Sea was lowered about 4.6-2.2℃ The above-mentioned features resulted from increasing of winter monsoon in the coastal region of South China and from increasing of north-east monsoon drift in the northern part of South Chins Sea during the last glacial maximum of Late Pleistocene

Key words: Paleoenvironmental features. Late Pleistocene, the coastal region of South China
