EVOLUTION OF ANCIENT CULTURE TYPES AND REGIONAL DIFFERENTIATION OF THEIR PROPAGATION AND SUCCESSION MODELS: A PRELIMINARY STUDY
初论古文化类型演替与传承模式的区域分异——以西拉沐沦河流域和汶泗流域为例

The landform framework of China was divided into three steps from west to east. The Xar Moron River watershed area is located on the transion area between the middle and lower steps of the landform framework. It is a moderate uplifting and downcutting area. Landform changes due to the uplifting and downcutting forced ancient men in the Xar Moron River watershed moving frequently in order to go after water sources or void floods. This frequent moving resulted in the existence of a single-culture at most of archaeological sites in the Xar Moron River watershed. That is, only a culture layer was discovered at a site, or some big break occurred between different culture layers at the same site. This is an unstable culture propagation and succession model. On the other hand, the Wen-Si Rivers watershed area, located on the lower step of the Chinese landform framework, has existed as a stable area without obvious uplift since Late Paleozonic. The landform there changed scarcely and so did habitations. Such environments resulted in the existence of a superposed culture at most of archaeological sites in the Wen-Si Rivers watershed. That is, different culture layers are vertically distributed at the same site, and some succession relation occurs between them. This is an intermittent culture propagation and succession model. These two models of culture propagation and succession reflect a regional differentiation of ancient culture types of China, mainly depending on the change of landform and natural environments.$$$$
