| 摘 要： | The intertidal zone of the Zhujiang River mouth tidal flat is about 570,000 mu in total, and the tidal flat of the subtidal zone (shallower than -2 m of the Huanghai Sea base level) is 560,000 mu. The two types, silty mud and argillaceous silt, are predominant in the tidal flat area, which can be divided into five types in terms of origin: 1) river mouth sand spit-subaqueous natural levee type; 2) river mouth bar type; 3) bay head type; 4) around the island type; and 5) marginal flat type. The tidal flat of the Zhujiang River mouth belongs to the depositional type and is constantly accumulating silt while extending, with an average land formation of 8,940 mu/yr in 97 years (1883-1980).
