Abstract: By the synthetical method, a systematic study of the surface-emerging ancient channels on the south coast plain of Laizhou Bay has been made. 25 surface-emerging ancient channels have been found and verified.According to the formed times, these ancient channels were divided into two stages: 6 palaeochannels formed in the Early and Middle Holocene, and 19 palaeochannels formed in the historical period. According to the landform features,the palaeochannels were divided into four types: upland palaeochannel belts,strip-shaped upland palaeochannels,trough-shaped depression palaeochannels, and ancient river beds. Among the four types, the strip-shaped upland palaeochannels are the main type.
