中国北方史前遗址稻作遗存的植物硅酸体判别标准

Phytolith diagnostic characteristics of rice remains at prehistoric settlements in North China

利用植物硅酸体方法鉴定考古遗址中的栽培稻遗存,关键之一就是确立鉴定标准。通过对野生稻生长的环境背景进行综合分析,提出在中国北方地区,在全新世时期,特别是仰韶时代和龙山时代,不具备野生稻生长的气候条件;在考古遗址中发现的稻属植物硅酸体可以被看成是栽培稻的遗存。

To identify rice remains by phytolith analysis at archaeological sites, one of the most important points is to set the diagnostic characteristics of phytolith shape. In this paper, by comprehension of the environment of wild rice growth, the idea has been put forward that wild rice could not survive even during the optimum period of Holocene; and so the standard phytolith shape of rice genus can be used to identify cultivated rice at prehistoric settlements in North China.
