中文摘要：

虎头梁遗址位于河北省阳原县泥河湾盆地，距今1万年左右，出土的石制品加工精致、器型稳定。本文选择其中代表性的尖状器进行功能研究，通过微痕分析探讨其使用方式，并结合其形态特征探讨器物类型与功能之间的关系。对5个亚类型共52件标本的研究表明，虎头梁尖状器具有专业分工，并被装柄使用。这种工具的制作和使用特征反映了更新世末期虎头梁人群通过提高工具的效能来应对环境变化的生存策略。

英文摘要：

This study presents results of usewear analysis on lithic tools unearthed from Hutouliang, an Upper Paleolithic site in the Nihewan Basin, North China. The Hutouliang lithic assemblage includes predominantly finely retouched formal tools especially morphologically defined points. This study selected 52 out of 73 of these points, which are in previous typological analyses divided into 5 subtypes. Lithic use-wear analysis is used to examine microseopically edge damage and surface rounding in order to assess how these tools were employed. Stone tool use patterns revealed by usewear evidence suggests that humans living at the Hutouliang site made full use of pointed tips and edges for penetrating, scraping, and cutting, and that most of these points may have been halted. Based on the usewear data and typological observations, we conclude that the Hutouliang people made and used specialized and eurated stone tools in order to adapt to the changing climatic environment about 10000 years ago.
