Loop Area Neolithic Environmental Archaeology Preliminary Study

In this article, including-northwest of Shaanxi province and southern areas of Neimenggu province's Neolithic (approximately since 7000 ~ 4000BC) to study the spatial and temporal scales between Longshan era and Yangshao era's archeology .Sought in the region of the archeology culture and the environment change. To explore the relationship between the human natural and environment.First at all, over the years based on archaeological data and the results of previous studies, the establishment of the Neolithic Hetao area school sequence of cultural development. Secondly, based on the typical location of sample collection sites, or the correspondence between strata, to create a contrast with the archaeological and cultural environment of the archaeological sequence stratigraphic accumulation. Finally, analysis of the relationship between the cultural of archaeological development and the environment change in the natural. And reached the following recognizes:First, the North Loop area is situated in the middle of the farming-pastoral zone, the location just in the sub-humid, semi-arid zones of the transitional zone, therefore, ecosystems is fragile, and the climate sensitive to change. Since the study of Holocene environmental changes in the climate of our deep understanding of the region and the subsequent history of the Neolithic period of human culture and its important characteristics of the times one of the bases.Secondly, the times Yangshao Hetao Neolithic region by the middle reaches of the Yellow River Megathermal Yangshao all times the impact of culture expansion. Loop regions in which the emergence of the Neolithic culture Megathermal Yangshao culture and the north and one after the Hougang culture is closely related to movement to the northwest; Yangshao era, the development of advanced culture and Yangshao Guanzhong region, the advanced culture of the first meeting of the North into the lead of cultural exchange and influence.Thirdly, the Longshan low damp events, resulting in the Loop area of the Neolithic culture change and the spatial distribution pattern of change. Northern Shaanxi Longshan era surge in the number of sites and settlements Hetao Shicheng the emergence of the region are related to cooling events in different regions of the movement of human culture and cultural conflict. In addition, the spatial distribution of Shicheng with change and climate change caused by sub-humid areas and semi-arid regions of the dividing line is closely related to the movement.
