摘　　要：通过对广富林遗址05SGIT1240探方样品,马桥遗址05MMT4探方样品的孢粉、藻类研究,并根据孢粉、藻类成分特征,发现在良诸文化后期,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)等数量较多,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已有的资料,推测太湖地区良渚文化突然消亡的原因是水泛.According to the study on sporo-lmllen and alga form 05SGIT1240 in Guangfulin relics and 05MMT4 in Maqiao relics, some Typha, Cyperaceae, Phragmites, and Salvinia of hydrophytes are founded in the upper samples of Liangzhu culture. In addition, there are also plenty of Concentricystes and Zegnema, which grow in fresh water. Based on the former research and the foraminifera research, the analysis result shows that the vanishment of Liangzhu Culture in Taihu Lake is caused by the flood.
