极端气候环境事件及其对人类社会的影响，是当前全球变化研究的热点和薄弱环节。选择关键区域重建气候环境历史，尤其是极端气候事件，是评估未来气候变化影响与后果的突破口。杭嘉湖地区作为稻作农业发祥地，新石器时期文化繁荣，古人-地作用关系典型，是研究早期人类活动对环境变化的适应方式和策略的理想区域。本项目选择杭嘉湖南部地区重点考古遗址及周边自然岩芯剖面，在高精度AMS14C测年基础上，建立区域地层层序，并精细刻画全新世地貌演化。继而开展沉积学、微体古生物学、地球化学等环境替代指标综合分析，重建高分辨率气候环境变化序列，重点厘定极端环境事件，探讨环境变化、尤其是极端气候环境事件对新石器文化的影响，为过去全球变化中的“人-地”关系研究提供科学认识。

The extreme climate events and their influence on human society are not only the hot spot but also weakest part in the field of global change research. To reconstruct climatic and environmental changes in the past, especially the extreme climate events, significantly depends on the right research area. This is also the very key to assessing the impacts and consequences of future climate changes. Hangjiahu Plain was one of the first places with domesticated rice, and Neolithic culture thrived on this very plain. This place was faced with great ecological and environmental changes and strong man-land interaction, which is an ideal research area to study human beings’ adaptation to future climate changes. In this project, natural sediment profiles in and around the key archaeological sites in the southern plain are selected to set up a framework of sequence strata and depict the fine course of landform evolution during the Holocene according to a high resolution age model based on AMS14C dating, which will be followed by analyses of paleoenvironmental proxies including sedimentological, micropaleontological and geochemical index to reconstruct a high resolution sequence of climate change and determine the extreme climate events as the key part. The impact of environmental change, especially the extreme climate events, on the Neolithic culture will be discussed, providing a scientific basis for man-land relationship in the field of past global changes.
