摘要
利用综合方法对莱州湾南岸平原地面古河道做了系统研究，发现并验证地面古河道２５ 条，按形成时代将其分为两期，其中，早—中全新世古河道６ 条，历史时期古河道１９ 条；按地貌形态将其分为４ 种类型，包括高地古河道带、条状高地古河道、槽状洼地古河道和古河槽，其中条状高地古河道为该区主要的古河道类型。
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.
