Abstract:

Based on the investigation and excavation, emphasis was placed on gaining an appreciation for post-depositional processes that form and shape site and examining the effects of natural processes on temporal and special patterns of archaeological sites at Guanting Basin. As to the distribution of archaeological sites, the following features are shown after investigation and excavation: (1) the sites transferred vertically on temporal and special patterns; (2) the earliest cultural layer deposited on the second terrace is Majiayao type of Majiayao Culture, suggesting that the ancient men moved to the second terrace at least during 3169-2882 a BC; (3) the number of sites increased abruptly during Qijia Culture period; (4) the human beings repeatedly occupied the second and third terraces during one culture period; and (5) the sites of Qiajia culture on the second terrace were not covered by the successive culture deposit, but were on the third terrace.

Key words: Guanting Basin of Qinghai Province, cultural deposits, environmental settings
