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

The data set contains respiratory inflammatory indexes collected from four follow-up visits of native Tibetans in Lhasa and Nyingchi, Tibet Autonomous Region. The project carried out four follow-up surveys in Lhasa and Nyingchi from May to June and September to October 2021, and a total of 212 subjects were recruited. Fractional exhaled nitric oxide (FeNO) is produced by airway cells. Its concentration is highly correlated with the number of inflammatory cells. It is a simple and noninvasive biological index, which can effectively reflect the degree of airway inflammation,. At each visit, about 5 liters of exhaled gas were collected with Teflon air bag, and then the content of nitric oxide (FeNO) in exhaled gas was measured with thermo NOx gas analyzer to characterize the inflammatory level of respiratory system. The data can be used to evaluate the level of respiratory inflammation of native Tibetans in Tibet, and further analyze the effects of ozone exposure and hypoxia on respiratory inflammation of natives.

Biological samples of subjects were collected at each visit. The professional nurses of Lhasa Second People's Hospital and Nyingchi Jianmin hospital collected 18 ~ 20ml blood samples, and some samples were sent to the hospital for analysis. The related indexes of leukocytes such as lymphocytes, basophils, neutrophils, eosinophils and monocytes can reflect the level of systemic oxidative stress inflammation. The data can be used to evaluate the level of systemic inflammatory oxidative stress of native Tibetans in Tibet, and further analyze the effects of ozone exposure and hypoxia on systemic inflammatory oxidative stress of permanent residents.
The data set included lung function and cardiovascular function indexes collected during four follow-up visits to the high altitude natives in Lhasa and Nyingchi, Tibet Autonomous Region. Four follow-up surveys were conducted in Lhasa and Nyingchi from May to June and September to October 2021, and a total of 212 subjects were recruited. During each visit, the forced vital capacity (FVC), forced expiratory volume in one second (FEV1), vital capacity (VC) and other pulmonary function indexes of the subjects were measured by Mir pulmonary function instrument. The heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), augmentation index (AIx), carotid femoral pulse wave velocity (cf-PWV) and other cardiovascular function indexes were measured by German vicorder cardiovascular detector. The data can be used to evaluate the cardiopulmonary system function of natives in Tibet, and further analyze the effects of ozone exposure and hypoxia on the cardiopulmonary system function of high altitude natives.
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.
Quantitative evaluation and comprehensive measurement of resource and environment carrying capacity is the key technical link of resource and environment carrying capacity research from classification to synthesis. Based on the evaluation of the suitability of human settlements, the limitation of resource carrying capacity and socio-economic adaptability, and according to the research idea and technical route of "suitability zoning restrictive classification adaptability classification warning classification", a three-dimensional tetrahedral model for the comprehensive evaluation of resource and environmental carrying capacity with balanced significance is constructed. Based on the 10km grid, a comprehensive study on the resource and environment carrying capacity was carried out, and the resource and environment carrying capacity index of the areas along the silk road was quantitatively simulated. Taking 1 as the equilibrium significance, it provided support for the comprehensive evaluation of the resource and environment carrying capacity of the areas along the silk road.
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.
