从渔猎采集到食物生产:大连广鹿岛小珠山遗址动物驯养的稳定同位素记录

From Hunting and Gathering to Food Production——Record of Stable Isotope about the Animal Domestication in Xiaozhushan Site,Guanglu Island,Dalian City

本文通过对小珠山遗址动物遗存的碳氮稳定同位素分析发现,小珠山遗址第二期开始,海洋性食物对于遗址狗的饲养具有非常重要的贡献,而从小珠山遗址第三期开始部分狗的食物中已经有了大量的粟作农业产品。值得注意的是,根据碳同位素可以看出,小珠山遗址第三期开始,部分猪的食物中明显包含少量的C4类食物。鉴于从小珠山遗址第三期开始猪骨的数量比例大幅度增加、同时三期又出现了用粟类食物喂养的狗,我们保守的认为小珠山遗址第三期时期广鹿岛已经出现了家猪。结合猪和狗的食物结构,我们认为至少从小珠山遗址第三期开始,粟作农业生产就开始对小珠山遗址的家畜饲养产生了一定的影响。

As a secondary, setting of agricultural origins, small islands in southeast coast of Liaoning province may offer insights into the social interactions involved in food production and the human modification of local landscapes to accommodate a new horticulture way of life. Animal diets at Xiaozhushan site in Guanglu Island, Dalian City, were investigated using stable carbon and nitrogen isotopes in this paper, in order to explore economic adaptation and transitions to food production in the specific ecological and social settings, which might happened after impulses from environmental change and human migration.
