杭州湾南翼全新世环境分异耦合过程与新石器人类响应与适应

为应对未来多重压力下河口-海岸地区的可持续发展问题，需要从不同的时间尺度去了解气候、环境变化的过程、特征、机理及人类响应和适应方式。作为未来全球增温、海平面上升背景下的历史相似型，全新世早中期以来河口-海岸地区的人地关系，可为深刻认识我国沿海地区海陆交互环境特征、地貌形成机理、演化趋势和应对未来挑战提供历史借鉴。 . 在杭州湾南翼开展一系列钻探取芯，通过钻孔沉积学、地貌学、年代学以及代用指标的综合分析，建立南翼全新世以来地貌环境分异耦合演化的时空过程与特征，甄别海平面波动与极端气候环境事件在不同沉积记录中的反映；集纳考古记录的人类活动信息，与钻孔孢粉、植硅体和炭屑等指标获取的人类活动信息做对比和集成分析；在相同的时空框架下，分析地貌演化过程与新石器遗址分布特征、人类生产、生活方式等信息的对应关系；探讨气候-海平面变化驱动下的环境分异耦合过程与新石器人类的适应、响应方式和机理。

It is necessary to understand the processes, characteristics and dynamics of climate and environment changes on different time scales in order to cope with future multi- pressures for a sustainable development on the estuarine and coastal regions. As historical analogue of future global warming and sea-level rising, the features of human-environment interactions since the early to middle Holocene on the estuarine and coastal regions would give insights into the understanding of the present characteristics and the dynamics of coastal environment processes and provide historical references for future challenges. . Sediment cores are planned to obtain on the south flank of Hangzhou Bay, eastern coast China. Integrated analysis of sediment cores including sedimentary facies, chronological establishment and proxies will be conducted to set up the temporal and spatial characteristics of geomorphological changes especially the differentiation and coupling processes, and also to identify the imprints of sea-level and extreme environmental processes in different sedimentary records. Information of human activities retrieved from archaeological findings, excavation reports and from pollen, phytolith and charcoals evidences of sediment cores are being correlated and synthesized to reflect the human presences during the Neolithic times. On the same framework of chronology, the relations on similarities and differences of geomorphological features and distribution of human dwells, immigration routes and human subsistence will be established. Finally, the mechanism of human responses and adaptations to the differed and coupled dynamics of climate, sea level and geomorphological changes since the early Holocene on south flank of Hangzhou bay are discussed.
