Abstract: The Hake site located in the Hulunbeier area is a typical microlithic site and therefore is of great importance in discussing microlithic cultures and their origin in North China. The site is situated on a half-enclosed island, surrounded by the Hailaer River to the east, north and south. The deposits of this site are divided into four cultural layers, with the microlithic layer being the thickest. A comprehensive analysis of the archaeological deposit indicates that the process of deposition corresponds with modern climatic changes, and thus the development of this culture is in consistent with climatic change, which provides an example of the human survival strategy of adaptation.

Key words: Environmental changes; Human behaviors; Holocene; Hake area
