英文摘要：

In August through October 2009, rescue excavation was conducted to the Yuzui Site, from the Zone 11 of which large amount of lithic products of the early Paleolithic Age were unearthed, including cores, flakes, chunks and implements. These lithic products were all made of locally quarried raw materials mainly by directly flaking with hammering method and coarsely retouched, and the main type of the implements were scrapers in various forms. The excavation and preliminary study of the Yuzui Site rather completely revealed the characteristics of the lithic product assemblage, enriched the knowledge about the features of the Paleolithic cultures in South China and provided important data for the further exploration on the behaviors and the adaptive strategies of the early human beings in the Han River valley.
