沿海洪水灾害过去曾多次影响到世界各地沿海平原的人类社会，并在全球变暖和海平面上升的背景下威胁着21世纪的社会。然而，沿海洪水在长江下游地区新石器时代良渚文化中断中的作用一直存在争议。在这项研究中，我们使用了一个年代较长的新石器时代遗址（玉山遗址），靠近现在的海岸线，来证明良渚文化末期的一次海洋溺水事件，并讨论了它与相对海平面上升的联系。本文对玉山遗址几个典型剖面的沉积学、年代学、有机元素组成、硅藻和鞭毛藻囊进行了分析。野外和沉积资料提供了明确的证据，表明在公元前2560年左右，一次古台风袭击了玉山遗址，预示着该遗址的海洋淹没和生态恶化时期。根据玉山沉积记录推断，在公元前2560-2440年，海平面上升加速，这解释了当时长江南部沿海平原普遍存在海岸洪水的特征。这次全新世中期沿海洪水发生的时间与长江下游地区先进而广泛的良渚文化突然消失的时间一致。我们推断，伴随海平面加速上升的极端事件和洪水是史前沿海社会脆弱性的主要原因。
Coastal flooding catastrophes have affected human societies on coastal plains around the world on several occasions in the past, and are threatening 21st century societies under global warming and sea-level rise. However, the role of coastal flooding in the interruption of the Neolithic Liangzhu culture in the lower Yangtze valley, East China coast has been long contested. In this study, we used a well-dated Neolithic site (the Yushan site) close to the present coastline to demonstrate a marine drowning event at the terminal stage of the Liangzhu culture and discuss its linkage to relative sea-level rise. We analysed sedimentology, chronology, organic elemental composition, diatoms and dinoflagellate cysts for several typical profiles at the Yushan site. The field and sedimentary data provided clear evidence of a palaeo-typhoon event that overwhelmed the Yushan site at ∼2560 BCE, which heralded a period of marine inundation and ecological deterioration at the site. We also infer an acceleration in sea-level rise at 2560–2440 BCE from the sedimentary records at Yushan, which explains the widespread signatures of coastal flooding across the south Yangtze coastal plain at that time. The timing of this mid-Holocene coastal flooding coincided with the sudden disappearance of the advanced and widespread Liangzhu culture along the lower Yangtze valley. We infer that extreme events and flooding accompanying accelerated sea-level rise were major causes of vulnerability for prehistoric coastal societies.
