The population, grain, grain sown area and year-end data sets are extracted from the provincial and prefecture level statistical yearbooks of Qinghai, Tibet, Xinjiang, Gansu, Sichuan and Yunnan for many consecutive years. The missing data are interpolated as follows: 1. To ensure the accuracy of county data, Some counties and cities have been merged in this data (there may be errors in dividing and imputing the data for 20 years according to the proportion, but there will certainly be no problem in the merger, and the county area is small, so it is merged). 2. Xiahe County and cooperative city are merged into Xiahe County (cooperative city was separated from Xiahe County in 1998). 3. Gucheng district and Yulong County are merged into Gucheng district (Lijiang County was divided into Gucheng district and Yulong County in 2003). 4. The inner city district, East City District, West City District The four districts in Chengbei district have been merged into the district directly under the central government of Xining City (because the population of the four districts is given separately or the sum is given, and the total area of the four districts is only 487 square kilometers, they are merged). 5. For some missing data, curve fitting has been carried out in combination with similar years, and R2 is between 0.85-0.99. 6. In order to ensure the accuracy of the data, change maps have been prepared County by county

This data uses a landslide hazard risk assessment model consisting of four modules: landslide hazard causative factors, landslide susceptibility model, exposed population and population casualty rate. The module of hazard-causing factors includes DEM, slope, rainfall, temperature, snow cover, GDP, and vegetation cover factors. The landslide hazard susceptibility model is a statistical analysis using a logistic regression model to obtain landslide susceptibility probability values. The population exposure module uses the landslide susceptibility values overlaid with population data. The population casualty rate module is based on the ratio of historical landslide casualties to the population exposed to landslides during the same period. Finally, by substituting the 2020 population data, the exposed population under different levels of landslide hazard susceptibility is calculated and multiplied with the historical period landslide hazard population casualty rate to assessIntegrated multi-hazard population risk in the peri-Himalayan and Asian water tower regions

Human adaptation to high altitude environment (> 2500m) is an important milestone in the process of human evolution and diffusion. As the highest altitude and largest plateau in the world, the Qinghai Tibet Plateau is an ideal area for human adaptation to extreme hypoxia environment. An early site with continuous strata, the site of jijunbu, was newly discovered on the Bank of Zhuanglang River in Yongdeng County, Gansu Province, northeast of Qinghai Tibet Plateau. A series of samples were taken from the site in 2015 and 2018. The results of photoluminescence dating show that the age of the site is 120-90 Ka, which is the earliest wilderness site on the Qinghai Tibet Plateau, providing new clues for the study of early human activity history and survival adaptation on the Qinghai Tibet Plateau.

To investigate the paternal genetic structure of Tibetans, 447 male samples were collected from Ngari (n=211), Chamdo (n=119), and Nyingchi (n=117). Firstly, SNP genotyping was performed to allocate samples into haplogroups. To further evaluate the genetic diversity of the major Y-chromosomal haplogroup in Tibetan populations from Lhasa, eight commonly used Y-chromosomal STR (short tandem repeat) loci (DYS19, DYS388, DYS389I, DYS389II, DYS390, DYS391, DYS392, and DYS393) were genotyped using fluorescence-labeled primers with an ABI 3130XL Genetic Analyzer (Applied Biosystems, USA). The results indicated that haplogroup D displayed highest frequency in these three Tibetan populations (Ngari 54.50%, Nyingchi 64.10%, Chamdo 67.23%). Among haplogroup D, D-P47 showed the highest frequency (Ngari 29.39%, Nyingchi 51.28%, Chamdo 55.46%). Differently, D-N1 showed the highest frequency in Ngari (21.33%), followed by Nyingchi (11.97%) and Chamdo (10.92%). Haplogroup O-M117 is the second frequent haplogroup in these three populations, with the highest frequency in Ngari (29.86%), followed by Nyingchi (26.50%) and Chamdo (15.97%). Compared with the other two populations, Ngari Tibetans have higher frequencies of western Eurasian haplogroups, including R-M17 (1.42%), R-M343 (1.42%), and J, probably reflecting more genetic contribution from the west into Ngari. In combination with the data from Lhasa that deposited in 2019 and 2020, our Y chromosome data of Tibetans from different locations on the Tibetan Plateau will be very helpful to understanding the paternal genetic structure of Tibetans. Moreover, the genetic history of Tibetans can also be dissected by phylogeographic and coalescent analyses.

The Hindu Kush mountains are tall mountains in Central Asia. The average altitude is about 5000 meters, and the highest peak, tiriqmir peak, is 7690 meters above sea level. It is the watershed between the Indus River in the southwest of the Qinghai Tibet Plateau and the Amu Darya River in the Pamir Plateau. Studying the genetic structure of the population in this area will help to deeply understand the diffusion history of the population and the genetic basis of adapting to the plateau environment. Studying the genetic structure of the population in this area will help to deeply understand the diffusion history of the population and the genetic basis of adapting to the plateau environment. In this study, we studied the maternal genetic structure of 213 individuals from 5 populations distributed in Xingdu Kush mountains. The mitochondrial genome sequences of 213 individuals (average depth > 1000x) were obtained by mitochondrial genome capture library construction and second-generation sequencing (Illumina hiseq x ten platform). Based on the idea of phylogeny, we control the quality of these data to ensure that there are no quality problems such as sample pollution. The modified Cambridge standard sequence was used as a reference for the output of mutation sites. According to the mitochondrial DNA phylogenetic tree (phylotree. ORG) of people around the world, each sample was divided into haplotype groups. Based on the mtDNA data of modern population and ancient samples published in the past, the origin and diffusion history of population in this area were systematically studied. The results show that the main maternal genetic components of Indo European populations in this region come from western Eurasia. Haplotypes w3a1a and j1b1a1 may be related to the migration of Indo European language groups, indicating that the diffusion of Indo European language groups to South Asia may not only be a simple cultural expansion, but also accompanied by the migration of some people. In addition, the study also shows that northern Pakistan may play an important channel role in the diffusion of Indo European languages to South Asia.
