九寨沟地处四川盆地向青藏高原过渡的边缘地带,属高山峡谷地貌区。沟内地势南高北低,相对高差达2768米。在沟内高半山地带,分布有阶梯状的小型黄土阶坎(Terracette)。四川大学九寨沟联合实验室曾对九寨沟内阶坎地貌的形成机制进行了初步探讨,认为其很可能与古今人类的生产活动密切相关[1]。经过广泛踏查,最终在古洼寨、尖盘寨、扎如寨附近发现了古代遗址的线索,其中以阿梢垴遗址堆积最为丰富(图 Jiuzhaigou is located in the edge of the transition from the Sichuan Basin to the Qinghai-Tibet Plateau, a mountainous alpine landscape. The ditch is high in the north and low in the valley with a relative elevation of 2768 meters. In the high mid-valleys of the ditch, there are small steptte shaped terrace terraces. The Jiuzhaigou Joint Laboratory at Sichuan University once conducted a preliminary study on the formation mechanism of the Jikanggou topography in Jiuzhaigou and concluded that it is very likely to be closely related to the human and the ancient human activities [1]. After extensive investigation, the clues of the ancient ruins were finally found near the ancient wa village, the sharp disc village and the Zharu village. Among them,
