Abstract: Palaeodietary analysis is one of i portant fields in bioarchaeology, but there has been a lack of syste atic studies on this topic in China. Ele ental analysis of ancient hu an bones fro the Jiahu Site, Henan, was undertaken to investigate details on palaeodiet. The change of log( Sr/Ca) and log( Ba/Ca) during the whole phases indicated a lifestyle transition fro hunting and gathering to rice agriculture and ani al do estication. Abnor ality in the results of log ( Sr/Ca) and log ( Ba/Ca) in sa ple 249 was probably relevant to i igration to this region.

Key words: Palaeodietary analysis; Ele ental analysis; Rice agriculture; Animal do estication; Imigration; Jiahu
