The Study of the Surface-Emerging Ancient Channels on the South Coast Plain of Laizhou Bay

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.
