中文摘要：

一、研究背景石核剥片是一个递减的过程,可区分不同的阶段。有学者将体现不同剥片序列和阶段的石制品分类方法称为阶段类型学[1]。其将属于石核剥片的产品分成三类,即初始石片、再次石片和三次石片,其间还包括碎片和断块。这一般被认为代表了石核剥片的三个不同阶段,即初次剥片是最早剥下的石片,而三次剥片则是最晚剥下的石片。但这种分类实际上有很多问题,

英文摘要：

The results of the studies on the core flaking technique of the Wulanmulun Site showed that the core flaking technique in this site could be divided into two stages：the primary core reduction and the continued core reduction,and at least 17 flaking sequences have been identified.The different flaking sequences had some choices to the original shapes of the stone core blanks and the materials.This reflected that the diversity of the utilization of the original stone blanks and the methods,techniques and sequences of the flaking;the primitive people living in this site had not only superb flaking skill,but also rather strong planning and organizing abilities;some special sequences（such as the one containing C3.2.2 method） reflected the intentional production of the flakes with special technical features by the primitive people.
