Development of ancestors‘ cultivation revealed in phytolith assembalages from Guangfulin relics

Shanghai Museum has got great achievements in re-excavating Guangfulin relics. It is the first time that the cultural remains of Wangyoufang type is found above the Liangzhu cultural remains which comes from East Henan Province, providing previous materials for researching cul-ture evolution around Taihu Lake. Samples were taken from the immature soil layer and cultural layers of Guangfulin relics for phytolith analysis. According to the systemic re-search for the archaeological remains and phytolith fossil, the phytoliths in Guangfulin relics can be divided into four zones. The development of rice agriculture and living condi-tion of Guangfulin ancestors was discussed based on the ex-isting rice fan-shaped phytolith, rice shell phytolith, diatom fossil and archaeology evidence in the same layer. The Guangfulin relics has gradually developed since a high sea level 5000 years ago, and the broad rice agriculture has si-multaneously developed. The newly re-excavated relics pro-vides valuable materials for the research of ancestors and ancient culture in Shanghai.
