| 摘 要： | 良渚文化作为新石器时代晚期的重要文化之一,与中华文明的起源有着重要联系。位于杭州瓶窑镇的良渚古城遗址,则代表了良渚文化发展的巅峰。我们采集了良渚遗址剖面的文化层、上覆黄粉土的土壤样品以及遗址周边地区的河流和钱塘江的沉积物样品,测试分析了它们的Sr-Nd同位素组成。通过对比黄粉土和文化层的同位素组成变化,结合遗址周边环境和前人对长江沉积物、东海沉积物的研究,我们推测,良渚黄粉土物质来源可能是东海、长江沉积物和钱塘江沉积物的混合,良渚文化可能并非消亡于来自周边山体的山洪,而是与海侵或者长江下游洪水泛滥有关。

| Abstract: | Liangzhu Culture is an important culture in the late neolithic age and has a significant connection to the origin of the Chinese
civilization. The archaeological site of Liangzhu ancient city located in Pinyao, Hangzhou, represents the crown of Liangzhu
development. Wecollected soil samples from the Liangzhu cultural layer, the overlying silty soil and the sediments of surrounding rivers and the Qiantang River, measuring and analyzing their Sr-Nd isotopic compositions. Comparing variations between the silty soil and the soil of the Liangzhu cultural layer, together with some recent studies of the sediments of the Yangtze River and the East China Sea, we infer that the silty soil may be a mixture of sediments from the East China Sea and the Qiantang River. Therefore, transgression during that period may result in the collapse of the LiangzhuCulture. |
