林富遗址位于黑龙江省富裕县友谊达斡尔族柯尔克孜族乡林富村西的岗地上,该遗址于第三次文物普查时发现。2011~2013年黑龙江省文物考古研究所多次对该遗址进行调查和试掘，获得了一批石制品和测年样本。本文以2011~2013年试掘和调查所得的石制品为研究对象，从石核剥片的角度对石制品进行技术分析。石核剥片策略显示，遗址内存在两种剥片体系：石片石核技术体系和细石叶技术体系。石片石核剥片采用锤击法，剥片模式包括台面和剥片面固定和不固定两种模式。标本技术阅读发现台面和剥片面固定模式的剥片体系受到了细石核技术影响；细石叶技术剥片采用压制法，技术分析显示林富遗址既有华北地区的船形细石核技术又有我国东北地区楔形细石核技术，这两种技术体系在处于末次盛冰期后夏季季风最盛期的林富遗址内出现了交叉融合，印证了细石叶技术在末次盛冰期时期形成的二元分化格局，反映了在二元分化格局下人群的扩散与技术交流。

The Linfu site is located in the west of Youyi Dagur Kirghiz Linfu village, Fuyu County, Heilongjiang Province. The site was found during the third cultural relics census, and the Heilongjiang Provincial Institute of Cultural Relics and Archaeology has conducted several investigations and test excavations of the site from 2011 to 2013 and has obtained a number of stone artifacts and dating samples. A total of 2567 stone artifacts were discovered at the site. The lithic assemblage is dominated by flakes and chunks, mainly produced by direct hammer percussion. Tuff is utilized as the main material used for the lithic technology of the ancient occupants. The raw material were all derived from river gravels.

This paper presents a specific lithic analysis of stone artifacts. The flaking strategy of the cores showed that two technology types existed at the site: flake-core technology and microblade technology. The results show that core reduction is characterized by hard-hammer percussion, including platform and working face fixed and unfixed. Technology analysis found that the faking core of the fixed mode of working face was influenced by microblade technology. Microblade technology, characterized by pressure flaking, has been analyzed technically at the Linfu site. The findings indicate that this site exhibits both the boat-shaped microblade technology typical of North China and bifacially prepared wedge-shaped cores associated with Northeast China. These two technological systems are integrated within the Linfu site. The Linfu site was formed during the height of the summer monsoon after the LGM (Last Glacial Maximum), and its stratigraphic accumulation is thick and stone artifacts are dense. This temporal context reflects the movements and migrations of ancient populations under a dichotomous pattern.

The technological study of the site provides a new reference for revealing the origin, dispersal, and development of microblade technology in the Nenjiang River Basin and thus opens a window for researchers to discuss ancient human behavior and dispersal in this area. The discovery of this site is of great significance to how hominids in Northeast and North China and even in Northeast Asia responded to the adaptation of the environment before and after the LGM. At the same time, it also provides important materials for research on the origins of microblade technology and the evolution of craftsmanship, modern human behavior, and migratory diffusion.
