1.Archaeological sites in Lhasa and Nyingchi

The Tibetan Plateau has a harsh conditions for human to inhabit. When human beings went into the Tibetan Plateau and how they adapt to the extreme environment have attract broad attention. At present, extensive studies on this issue have been conducted in the northeastern Tibetan Plateau with few work in other regions. There are a lot of archaeological sites in the Yarlung Zangbo River Basin while most of them are lack of cultural layers. Systematic archaeological investigations had been done to 25 cultural layers and 3 tombs in Lhasa and Nyignchi

2.Distribution dataset of prehistoric era ruins on the Tibetan Plateau and its surrounding areas

This data is the distribution data of the prehistoric era sites on the Qinghai-Tibet Plateau and surrounding areas, which is derived from the Supplementary Maps of the paper: Chen, F.H., Dong, G.H., Zhang, D.J., Liu, X.Y., Jia, X., An, C.B., Ma, M.M., Xie, Y.W., Barton, L., Ren, X.Y., Zhao, Z.J., & Wu, X.H. (2015). Agriculture facilitated permanent human occupation of the Tibetan Plateau after 3600 BP. SCIENCE, 347, 248-250. The Qinghai-Tibet Plateau, with an average altitude of more than 4000m, is the highestand largest plateau all around the world, and also is one of the most unsuitable areas for human life with long-term on the earth. The remains at the archaeological site are direct evidences left behind the ancient human activities. The original data of this data is digitized from the results of the Qinghai-Tibet Plateau high-textual census and archaeological survey (Qinghai Volume and Tibet Volume of the Chinese Cultural Relics Atlas). The map was digitized mainly based on the distribution maps of the sites, and the latitude and longitude coordinates and altitude were obtained. a total of 6,950 sites, most of which are distributed in the northern part of the plateau. The age range of the site is between 7000BP and 2300BP. This data set is of reference value for the research on the process and power of human diffusion to the Tibetan Plateau in the prehistoric era and other studies related to human activities in the Tibetan Plateau and the prehistoric era.
