The scope of Guangzhou City is roughly the foothills of Baiyun Mountain in the north, the Leizhou Chau in the south, the Huangpu in the east, the west of Fangcun in the west and Zhu Shasha, covering an area of about 380 square kilometers. This article focuses on the changes of the ancient coastline in Guangzhou since Holocene. Based on the analysis of about 150 borehole data in the urban area, the observation of artificial sections and the identification of paleontological fossils, this paper proposes the scope of transgression of the Guangzhou coast since Holocene, that is, the location of the ancient coastline.
