Lajia Site, located near the upper reaches of the Yellow River and the border of Qinghai Province and Gansu Province, is a large-scale site of the Qijia Culture. In 2000 and 2001, archaeologists excavated an unusual scene of prehistoric dramatic and miserable disasters. Lots of geo-logic-geographic evidences revealed that the Lajia Site was ruined by coinstantaneous disasters, mainly floods from the Yellow River and earthquakes, accompanying mountainous torrents. Study on these disasters and their driven forces could provide us not only the knowledge on the palaeoenvi-ronment of the area, but also offer us a valuable site to assess the influence of the natural disasters on human civilization development.
