对广富林遗址05SGIT1240探方样品、马桥遗址05MMT4探方样品进行了孢粉、藻类研究,并根据孢粉、藻类成分特征,发现在良渚文化后期样品中水生植物花粉香蒲(Typha)、莎草科(Cyperaceae)、禾本科(Gramineae)中的芦苇及水生的蕨类植物槐叶萍(Salvinia)等有较多数量,淡水生的藻类环纹藻(Concentricystes)、双星藻(Zegnema)也相当丰富。结合有孔虫研究及前人巳有的资料,我们推测太湖地区良诸文化突然消亡的原因是由水泛造成的。
According to the study on sporo-pollen and alga form 05SGIT1240 in Guangfulin relics and 05MMT4 in Maqiao relics,some Typha,Cyperaceae,Phragmites,and Salvinia of hydrophytes were found in the upper samples of Liangzhu culture.In addition,there were also plenty of Concentricystes and Zegnema,which lived in fresh water.Combined with the former information and foraminifera,the causes of the disappearance of Liangzhu culture in Taihu Lake area came from the flood water.
