渝东峡江区全新世环境考古与环境变迁研究现状

RESEARCH STATUS IN ENVIRONMENTAL ARCHAEOLOGY AND ENVIRONMENTAL CHANGE IN THE YUDONG RIVER VALLEY AND THE SANXIA REGION SINCE THE NEOLITHIC AGE

渝东峡江区全新世环境考古与环境变迁研究,目前的成果主要涉及部分遗址点的古环境复原、个别次流域环境变迁研究及初步建立的古洪水发生序列,在研究思路、方法和手段上仍需考虑区域特殊性并重视:①反映人地关系互动的环境考古研究,包括人类生存环境的生态条件、环境质量及人类对环境的影响能力方面;②遗址“次生堆积”的环境影响因素研究和“事件层”多成因分析;③遗址地层与自然地层的对比研究、区域环境考古及其比较研究;④区域古环境变化序列与全球变化区域响应研究;⑤确保获取高分辨率、满足多指标综合要求的沉积物样品。

Up to now, some research achievements in environmental archaeology and environmental changes in Yudong River Valley and Sanxia Region have been obtained, in relation to ancient environment, environmental change and ancient flood. However, the researched cultural sites are limited in several sub-rivers. As for further research, it is necessary to strengthen the practice and combination of theory and methodology between archeology and Quaternary geomorphology. In the meantime, we must emphasize the research of environmental archaeology, in which the archaeological ruins can reflect the interactions between ancient mankind and environment, including the ecological conditions and environmental qualities of the ancient mankind survival environment, as well as its impact on the environment. We then have to pay attention to the ＂secondary accumulation＂ research of the sites and the multi-factor analysis of the ＂invent layers＂, and to the research of global change in order to establish the environment evolutional sequence pertaining to a region. Comparative study should also be carried out between natural accumulation and cultural heritages in these regions. It is proposed that samples with multi-proxy and high-resolution should be accumulated for further research in these regions.
