Temperature-humidity index (THI) grid products of Qinghai Tibet Plateau (1km, 2017)

The temperature humidity index (THI) was proposed by J.E. Oliver in 1973. Its physical meaning is the temperature after humidity correction. It considers the comprehensive impact of temperature and relative humidity on human comfort. It is an important index to measure regional climate comfort. On the basis of referring to the existing classification standards of physiological and climatic evaluation indexes, combined with the natural and geographical characteristics of the Qinghai Tibet Plateau and facing the needs of human settlements suitability evaluation in the Qinghai Tibet Plateau, the temperature and humidity index and its suitability zoning results of the Qinghai Tibet Plateau (more than 3000 meters) are developed (including unsuitable, critical suitable, general suitable, relatively suitable and highly suitable).

Isotopic data of human bone and animal bone collagen at shilinggang site in the southwest of Qinghai Tibet Plateau

The basic principle of ancient recipe analysis based on carbon and nitrogen stable isotope analysis method is you are what you eat, that is, the chemical composition of animal tissues and organs is closely related to their diet. Through the detection of isotope ratio of relevant elements, the food structure of ancient people and animals can be directly revealed Then it discusses the research means of people's livelihood and livestock domestication. The collagen of human and animal bones from shilinggang site in Nujiang, Yunnan Province in the southwest of Qinghai Tibet Plateau was analyzed by carbon and nitrogen stable isotopes.

Chronological data of archaeological sites in Nyingchi, southeast Tibetan Plateau

The alpine and anoxic environment of the Qinghai Tibet Plateau is a major challenge for human survival and life. When human beings boarded the Qinghai Tibet Plateau and adapted to the extreme environment of the plateau has always been a hot issue in the academic circles. At present, in the study of prehistoric culture of the Qinghai Tibet Plateau, except the northeast, most areas of the Qinghai Tibet Plateau have not established archaeological cultural sequences. Yajiang river basin is one of the areas with dense distribution of human activity relics, but there are few archaeological excavations and studies, and the activity history of the ancients in this area is not clear. Based on the systematic dating of cultural archaeological sites in Linzhi Area, Southeast Tibet, 33 carbon fourteenth age data were obtained.

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

Socio-economic data set of Qinghai-Tibet Plateau (1982-2018)

The data set includes county-level demographic data of 252 areas in Qinghai-Tibet Plateau in 1982, 1990, 2000, 2010 and 2018, and GDP data in 1988, 1995, 2000, 2010 and 2015. The demographic data includes registered population, resident population, urban population, rural population, male population, female population and non-agricultural population. GDP data includes total GDP output value and GDP output value of primary, secondary and tertiary industries. The data are helpful to study the impact of human activities on the ecological climate of Qinghai-Tibet Plateau, and to explore the urbanization development, urban and rural population mobility, resident population change, local birth rate and agricultural population change in Qinghai-Tibet Plateau. The data were obtained by contacting the local statistics bureau, relevant statistical yearbooks and annual statistical bulletins of various places during the second scientific investigation of Qinghai-Tibet Plateau.

Basic information on cultivated land in the Tibet Autonomous Region (1959-2016)

The data set records the basic information of cultivated land in the Tibet Autonomous Region and contains two data tables. Among them, the data table 1 has 7 fields, and the data table has 5 fields, respectively recording the cultivated land area, dry land area, paddy field area, effective irrigation area, and national infrastructure area of Tibet Autonomous Region and each district and county from 1959 to 2016. , The units are all hectares. The data comes from: "Tibet Statistical Yearbook" and "Tibetan Social and Economic Statistical Yearbook", with the same accuracy as the statistical yearbook extracted from the data. This data set has important value for understanding the situation of cultivated land in the Tibet Autonomous Region, evaluating the level of cultivated land utilization, and researching agricultural production and food security.

Statistics of rural hydropower stations in Tibet in 2018

This data set is the summary of the survey results of rural small hydropower in Tibet in 2018. The main contents include the name, installed capacity, start-up time and completion time of small hydropower stations in different districts and counties of each prefecture and city in Tibet Autonomous Region, as well as the operation status of each hydropower station. The hydropower development in Tibet Autonomous Region has an early history. There are not many large and medium-sized hydropower stations, mainly in rural areas. With the development of social economy, most of the small hydropower stations in Tibet Autonomous Region have been shut down. At present, the development of large and medium-sized hydropower projects is the main one. In plateau areas where Hydropower Survey data are scarce, this data set reflects the history and current situation of small hydropower in Tibet Autonomous Region, and can provide a certain data basis for hydropower development survey and evaluation in Tibet Autonomous Region.

Tibet statistical yearbook

This data set is the statistical yearbook of Tibet Autonomous Region in different years, mainly including different social and economic statistical contents. The Tibet Statistical Yearbook is mainly based on statistical charts and analysis. It records the annual economic and social development comprehensively, systematically and continuously through highly intensive statistical data. Obtaining statistical data is a necessary prerequisite for economic and social research. With the help of Tibet statistical yearbook, it can provide data support for the social and Economic Research of Tibet Autonomous Region. Due to the lack of data in the Qinghai Tibet Plateau, it is difficult to find detailed socio-economic statistics on the network platform. This data set comes from the statistical departments of the Tibet Autonomous Region, which can provide support for relevant investigation and research.

A wolf in sheep's clothing: Elaphe xiphodonta sp. nov. (Squamata: Colubridae) and its possible mimicry to Protobothrops jerdonii

Based on the combined morphological, osteological characters and molecular phylogeny, we describe a new species of the genus Elaphe that was discovered from the south slope of the Qinling Mountains, Shaanxi, China, namely Elaphe xiphodonta sp. nov. It is distinguished from the other congeners by a combination of the following characters: dorsal scales in 21-21-17 rows, the medial 11 rows keeled; 202–204 ventral scales, 67–68 subcaudals; two preoculars (including one subpreocular); two postoculars; two anterior temporals, three posterior temporals; reduced maxillary teeth and dentary teeth number (maxillary teeth 9+2, dentary teeth 12; sharp cutting edges on the posterior or posterolateral surface of the rear maxillary teeth and dentary teeth; dorsa head yellow, three distinct markings on head and neck; a distinct black labial spot present in supralabials; dorsum yellow, 46–49 complete (or incomplete) large black-edged reddish brown blotches on body and 12–19 on tail, two rows of smaller blotches on each ventrolateral side; ventral scales yellow with mottled irregular black blotches, a few irregular small red spots dispersed on middle of ventral. Based on molecular phylogenetic analyses, the new species forms the sister taxon to E. zoigeensis. The discovery of this new species increases the number of the recognized species of the genus Elaphe to 20.
