Abstract: This paper is about new research on the Longgangsi locality of Liangshan site. At the southern foot of the Qinling Range, the Liangshan site is located in the upper reaches of the Hanshui River in Shaanxi Province and occupies a unique position in a transitional region of dividing northern and southern China. Discovered from the third terrace of Hanshui River in the 1950s and worked in 1980s, the Liangshan Paleolithic industry is known for its assemblage of chopper-chopping tools, spheroids, handaxes, cleavers, picks, and scrapers, etc. Bearing some morphological characters of the Acheulean tradition of most heavy-duty tool types, the Liangshan culture has close relationships with that of artifacts from Yunxian Man site, Dingcun, Lantian Man site, and Sanmenxia. This assemblage is also similar to Bose, Longgupo of southern China in terms of some characters of typology and technology. Research of Liangshan Paleolithic industry can help to lead to more discussion about environmental change and human migration in the geological period from late Lower Pleistocene to Middle Pleistocene.

Key words: Qinling range; Liangshan site; Lower Paleolithic
