山东日照市两城镇遗址土壤样品植硅体研究

A Phytolith Analysis of Soil Specimens from the Liangchengzhen Site in Rizhao City, Shandong

通过对两城镇遗址1999年发掘得到的土壤样品进行植硅体分析,发现在遗址中保存了丰富的水稻和其他禾本科植硅体化石。对来源于水稻的扇型植硅体化石进行形态参数分析,发现属于粳稻型。对植硅体组合的分析结果证明当时遗址周围气候温暖湿润,生态环境有利于水稻的生长和古文化发展。

As known from a phytolith analysis of the soil samples collected in the 1999 excavation on the Liangchengzhen site, plentiful phytoliths of rice and other cereals of the grass family exist in ash-pits and cultural layers of the site. A morphological parameter analysis suggests that the segment phytoliths left over from rice belong to japanica rice. Based on a phytolith composition analysis it can be concluded that the then climate around the Liangchengzhen site was rather warm and humid, and the e- cological environments were favorable to the growth of rice and the development of ancient culture.
