珠江三角洲是西、北江三角洲和东江三角洲的总称,实质上是两个没有成因联系的独立三角洲。但一般习惯上称它为珠江三角洲,如同习惯上把北江、西江和东江总称为珠江一样。 关于珠江三角洲的性质、形成和发展问题,前人曾做过许多工作。长期以来,地质学者和地理学者认为它是一个“湾头三角洲”。即认为它是由玉木冰期的冰体消融引起海面上升,淹没河口,并被西、北江和东江带来的沉积物充填河口湾而形成三角洲。从这一观 The Pearl River Delta is the general name of the West, the North River Delta and the Dongjiang Delta. It is essentially an independent delta that has no causal connection. But it is customary to call it the Pearl River Delta, just as it is customary to refer to the Pearl River as the Beijiang, Xijiang and Dongjiang rivers. With regard to the nature, formation and development of the Pearl River Delta, many previous work has been done by our predecessors. For a long time, geologists and geographers considered it a “Bayou Delta.” That is, it is believed that it is caused by the ablation of ice body in the Tamagawa Ice Age, causing the sea surface to rise, submerging the mouth of the river, and filling the estuary with sediments from the west, north and east rivers to form a delta.
