Through the chronology study of the typical pottery excavated from Xiaoling site in Xinjiang,this paper divides the Longshan period remains of Xiaoling site into three developmental stages,namely,Jingcun culture,Dongguan culture and Sanliqiao culture.Meanwhile,after the study of the layout structure of the kilns and the surrounding ancillary facilities in each period,it is suggested that the pottery industry at Xiaoling pottery kiln site prospered in the Jingcun culture stage,started to decline in the Dongguan culture stage,and may no longer be engaged in the pottery-related activities in the Sanliqiao culture stage.On this basis,issues such as the specialization level of pottery production at the Xiaoling pottery kiln site are discussed,and it is believed that the pottery production at the Xiaoling pottery kiln site has already developed to certain scale with fairly high level of specialization.
