宁波鱼山遗址浮选结果及分析

Analysis of Flotation Results from the Yushan Site in Ningbo City

鱼山遗址位于浙江省宁波市镇海区,为一处以河姆渡和商周地层为主体的遗址。本次对鱼山遗址开展采样、浮选工作,获得了大量河姆渡时期、良渚时期和商周时期的植物遗存,包括水稻、菱角、芡实、橡子、葫芦等可食性植物资源遗存,以及近20种其他乔木类和杂草类遗存。根据浮选结果显示可知,在河姆渡文化时期,生业模式经历了一个以采集狩猎为主逐渐依赖农业的转变,对植物资源的利用也由野生植物资源逐渐转向以水稻为主。而商周时期,水稻则占据最主要的地位,遗址以种植水稻为单一的农业模式。鱼山遗址植物考古发现,为探讨河姆渡文化时期宁绍平原的植物资源利用模式提供了新的证据,也填补了长江下游商周时期植物考古研究的空白。

The Yushan site is located in Zhenhai District, Ningbo City, Zhejiang Province, whose dominant remains were dated back to the Hemudu period and Shang and Zhou period. Through sample collection and flotation of Yushan site, a large number of plant remains from Hemudu, Liangzhu and Shang and Zhou periods were obtained, including edible plant remains like rice, water chestnut, gordon euryale, acorn and gourd, and nearly 20 other tree and weed remains. The flotation results show that during the Hemudu period, the mode of living industry experienced a slow shift from hunting-gathering to agriculture, and the utilization of plant resources also gradually shifted from wild plant resources to rice. While during the Shang and Zhou dynasties, rice became the main corps in this site. The analysis of plant remains at the Yushan site offers new evidence to the research of plant utilization in Ningshao plain during Hemudu culture period, and also enriches plant archaeology research in Shang and Zhou dynasties in the lower reaches of the Yangtze river.
