本文讨论末次冰期鼎盛时期华南沿海地区的古环境特征。对有关单位近年调查成果的分析,估计当时该地区的冬季温度比今低11-15℃,2月海洋表层水温此今低4.6-2.2℃,珠江三角洲地区河流深切达-40-62m以下,古海岸线推移到今水深150m左右深处。达主要是冰期世界气候寒冷,海面大幅度下降,东亚冬季风强盛、南海北部东北季风漂流增强的结果。

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
