摘要：乌江上游地区是贵州省旧石器时代遗存发现最为丰富的地区之一。本文将这一地区的旧石器时代遗存分为三期五段，并认为在该地区存在六冲河流域区和三岔河流域区两个文化小区。在旧石器时代晚期后段，两个小区的文化面貌发生了根本性的变化，六冲河流域主要是对本地固有的以小石片为主要特征的文化类型的继承和发展；三岔河流域转变成了以零台面石片为主要特征的文化类型，改变了这一地区固有的文化传统。

ABSTRACT: The upper Wu River valley, one of the regions yielding the most abundant Paleolithic remains in Guizhou Province, can be divided into two cultural areas: the Liuchong and the Sancha river drainage areas. Based on characteristics of cultural remains, human physical anthropology, stratigraphy, and geological chronology, Paleolithic remains in the upper Wu River are divided into three phases and fi ve stages. Substantial cultural changes happened in these two areas during the late Upper Paleolithic. The preexisting local cultural type represented by small fl akes continued and developed in the Liuchong river cultural area, while the cultural type in the Sancha river cultural area was transformed from the preexisting local tradition to one characterized by nullplatform fl akes.
