The lithic assemblage of Longquan Cave Site has been always grouped to the simple core and flake industry,especially dominated by small stone tools.The utilization of raw materials is limited.It reflects the flexibility and arbitrariness of modern humans from knapping,retouching and using the lithic artifacts.There are no obvious changes on the culture and technology of the lithic from different cultural layers.The subtle changes in this technology demonstrate the slow development of the technology itself.The results show that there are four different production strategies.People chose different production strategies in face of different types and shapes of the raw materials.We believe that Longquan Cave Site was formed by the reasons of culture and human behavior from the aspects of technological tradition,human evolution,resources and environmental changes.
