中文摘要：
青海丰台遗址是一处卡约文化遗址，约3200～2800aB．P．。通过对其灰坑中提取的淀粉粒分析了该区域当时先民们对植物利用情况。灰坑中包含了来自于小麦族（小麦属、大麦属）、粟、百合科及块根块茎类植物的淀粉粒，还包括可能来自于高粱（Sorghum bicolor（L．）Moench）、豆科豇豆属，或豌豆属及鹰嘴豆属的淀粉粒，但是高梁在该遗址中以前还未发现过，是否含有高粱淀粉粒需要其他证据验证。从发现的淀粉粒种类来看当时先民们利用植物的多样性。另外，结合浮选结果发现，该遗址中小麦族植物包括大麦（Hordeum vulare L．）和小麦（Triticum aestivum L．），但以大麦为主，可能是先民们对气候环境变化适应的结果。
英文摘要：
Fengtai Site, located at the west bank of the Shatangchuan River, is one site of Kayue culture （3200 2800aB. P. ）. In this study,we analyzed 22 starch grains from ash pits of the site to understand plants used by ancient people lived there. These 22 starch grains, either from different species or from different organs, can be divided into 6 groups： Tribe Triticeae [ wheat （ Triticum aestivum L. ） or barley （ Hordeum vulgare L. ） ], foxtail millet, or/and sorghum （Sorghum bicolor（ L. ）Moench） , bean, lily, root, and tuber. The bean may belong to the pea family,pisum,and the chick-pea family. Whether the starches from sorghum were contained or not, other evidences are needed because sorghum was not discovered at Fengtai Site before. These starch grains revealed the diversity of plants used by ancient people 3000 years ago. The fact that the starch grains of Tribe Triticeae are dominated in all starch grains reflected the climate of that time to a great extent.
