青海化隆沙隆卡遗址生业经济研究--来自淀粉粒的证据

Research on the Economic Subsistence of the Shalongka Site in Hualong,Qinghai:the Evidence of Starch Grains

通过对沙隆卡遗址陶片及石器表面残留淀粉粒的分析,发现了来自禾本科粟(Setaria italica)、小麦族(Triticeae)、壳斗科栎属(Quercus)、块根块茎类植物的淀粉粒,数量较为丰富,种属来源较为多样,显示了沙隆卡遗址先民植物性食物资源的多样性。壳斗科栎属、块根块茎类淀粉粒的发现,弥补了大遗存研究的不足,提供了沙隆卡先民植物性食物资源利用的新证据,为青海东部地区史前生业经济研究提供了一批重要的信息。

This paper presents the analysis of starch grain residue on the surface of sherds and stone tools from the Shalongka site in Qinghai.The result shows that identifiable species belong to Setaria italica,Triticeae,Quercus,and root tuber.The wide variety of plant remains suggests that ancient residents at the site might have relied on various food resources.The discovery of Quercus and root tuber provides additional evidence that was not recovered by macro-botanic remains,and new evidence for the study of plant food exploitation at the Shalongka site.In sum,this study provides important information for the prehistoric research on the subsistence in eastern Qinghai.
