Abstract: 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.

Key words: Yudong River Valley and Sanxia Region, Neolithic Age, environmental archaeology, environmental change
