AN OVERVIEW OF THE RESEARCH ON THE ENVIRONMENTAL EVOLVEMENT AND HUMAN-ENVIRONMENT RELATIONSHIP IN HOLOCENE EPOCH OF THE YANGTZE DELTA

综合分析了近20年来长江三角洲全新世环境演变与人地关系研究的进展,着重对长江三角洲的形成与演变、环境演变与人类活动、人地关系的历史演变、古环境研究方法等进行了综述。指出今后研究的主要内容,包括多种环境替代指标的相互验证,高分辨率研究,定量研究,加强环境质量的时空演变研究,加强综合研究,寻求人地关系协调发展的途径。

This paper aims to summarize the past research on environmental evolvement and human-environment relationship in the Yangtze delta, and to put forward some issues for further study. Much attention has been paid to the Yangtze delta formation and evolution from academic circle for its important role in regional economic growth and ecological environment.Many researches indicate that Yangtze delta has been the continental environment suitable for human settlement since the Holocene epoch.A large numbers of Neolithic sites, relics and wells excavated were discovered. After the termination of the Last Glaciation Age, the sea-level in the Yangtze delta was on the increase, and during about 7~6.5 kaBP,the sea-level reached the greatest range, closing to the sea-level of today. Sea-level changes and flooding events played an important role in the rise and fall of human civilization in the Yangtze delta region. The study of archaeological excavation and environmental archaeology indicate that the cultural interrupt in the sections of Neolithic sites are mostly the results of frequently occurred flooding events and extreme climatic events in this research filed. During the 3 kaBP,there is a great change of human-environment relationship. There are many methods to study environmental evolvement such as ~14C, spore and pollen, Geochemistrytechnique, etc. The main content of the following research in the field will focus on multi-proxy , high-resolution, quantificational and synthetical research. Meanwhile,it is quite necessary to emphasis on study of the temporal and spatial evolution of modern environmental evolution to find the path for sustainable development for human-environment relationship.
