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

(1) All data are measured at the station where each scientific research route is completed each time. (2) The sample number represents the team members and data contributors participating in the scientific examination; Different numbers represent different people. (3) Systolic blood pressure, diastolic blood pressure and pulse were measured by OMRON arm electronic sphygmomanometer; The data of blood oxygen saturation (SpO2) and heart rate were measured by fish jump finger clip oximeter; All hormones were determined by Shanghai ELISA kit. (4) There are two groups of blood pressure, pulse, oxygen saturation and heart rate data in each batch; One group (in the evening) is measured after arriving at a new destination, and the other group (in the morning) is measured before arriving at a new accommodation every day for breakfast; Hormone data were measured after blood collection in some accommodation points and taken back to the laboratory for treatment. (5) When the human body enters the high altitude hypoxic environment, heart rate, oxygen saturation and blood pressure are very sensitive response indicators. Blood pressure, heart rate and oxygen saturation are important indicators to reflect the degree of hypoxia. In particular, continuous detection of subjects can show the change process of hypoxic stress and adjustment. (6) From the perspective of physiology, it is analyzed that after people face hypoxic stress, the body increases or decreases the hormone level to maintain normal life activities, so as to achieve an adaptive protective mechanism, which provides a theoretical basis for the development of hypoxic drugs in the future; The choice of traveling on the plateau has a profound impact on the development of the plateau, which is not only conducive to the development of the plateau, but also has a profound impact on the development of the plateau.

Biodiversity is the sum of the ecological complex formed by organisms and their environment and various ecological processes related to it. It is expressed at all organizational levels of the life system, including genetic diversity, species diversity and ecosystem diversity. The higher the habitat quality, the better the biological habitat environment and the higher the biodiversity. In some studies, the habitat quality index was used to characterize biodiversity (Xiao Qiang et al. 2014). Habitat quality index (HQ) is a dimensionless comprehensive index to evaluate the habitat suitability and habitat degradation degree of regional land use types. Cultivated land, roads, towns and rivers are used as habitat stress factors to form sensitivity parameters. For the production of biodiversity products, the biodiversity modeling of ecosystem in national barrier area is studied based on land use data and invest model. Invest model has the advantages of less input data, large output data and quantitative analysis of abstract ecosystem service functions. It is an important means of biodiversity assessment at present. Based on the actual situation of land use in the Qinghai Tibet Plateau, five land use types with great impact of human activities, paddy field, dry land, urban land, rural residential area and other construction land, are selected as threat factors. Taking the land use data as the input variable of the invest model, the land biodiversity of the Qinghai Tibet Plateau with a resolution of 1 km from 2000 to 2020 is estimated based on the parametric model.

Naked barley, called highland barley in Tibet, is the main crop of the Tibetan plateau and the main food of the Tibetan people. It has a long planting history, the largest planting area, the widest distribution and the highest planting ceiling. As for the autonomous region, the annual sown area and total grain output account for more than half of the total sown area and total grain output. In river valleys below 4,200 meters, they account for 30-50% of the area sown to local crops. In the alpine farming area of 4,200-4,500 meters above sea level, it accounts for 70-90% of the planting area of local crops. Naked barley is almost the only crop at agricultural sites above 4,500 meters. Tibetan bare barley has strong cold and drought resistance and ADAPTS to the plateau climate conditions. It is distributed in the vast agricultural areas and farming-pastoral interlacing areas from more than 1,000 meters to 4,500 meters above sea level. At present, the upper limit of planting reaches 4750 meters, which is the highest limit of crop distribution in Tibet. In 1974, a comprehensive scientific expedition to the Qinghai-Tibet Plateau entered Tibet from Sichuan province and carried out investigations along the route. During a survey of wild barley in Jitang district, Chaya County, Qamdo region, Tibetan members provided information about semi-wild wheat, which is similar to wheat in morphology but has broken cob at maturity, and is generally mixed with highland barley and wheat fields as a field weed. Plant specimens and seeds were collected. When the expedition team arrived at the Institute of Agricultural Science and Technology of Tibet Autonomous Region, they learned that comrades Cheng Tianqing and Dong Yuao had collected a kind of wheat with broken cob at maturity in SAN 'an Qu Lin, Longzi County, Shannan Prefecture in 1962, which belonged to the same type as the materials we had collected in other areas of Tibet. Later, in the Xigaze regional agricultural research institute, Comrade Tan Changhua said that he had also seen this kind of wheat when the cob broke at maturity in Renbu County. In addition to the above areas, this wild wheat was also found near Jiacha county, Gongga County and Longzi County in Shannan during this year's investigation. Currently known distribution areas include lancang River basin, Yarlung Zangbo River basin and Longzi River basin.

Agriculture in Tibet is concentrated in the valleys of the Yarlung Zangbo River in south Tibet and the Nu, Lancang and Jinsha Rivers in east Tibet. The agricultural area of the valley accounts for 75 percent of the total cultivated land area of the autonomous region, and the grain output accounts for more than 80 percent of the total grain output of the autonomous region. Wheat and naked barley (known as highland barley in Tibet) are the main grain crops in The Tibet Autonomous Region, with the perennial sown area accounting for more than 80% of the total sown area, while the wheat and naked barley in the valley agricultural areas account for 75% of the sown area and 82% of the total yield of the region. The agricultural area of the valley is located between 28 ° and 31° north latitude, 2700 -- 4100 meters above sea level. It belongs to the temperate climate of the plateau, with better soil and water conservancy conditions and higher crop yield. But before liberation, under the dark feudal serfdom, the people lived in extreme poverty, and agricultural production was very backward, with the yield of grain per mu only over 100 jin. After liberation, especially since 1972, winter wheat was widely promoted in the agricultural areas of the valley, which promoted the reform of the farming system and significantly increased grain output. In 1975, the total grain output of the region increased by more than 50 percent compared with 1965, and by more than 1.5 times that of 1958 before the democratic reform. In 1977, the area sown with winter wheat was nearly 700,000 mu, accounting for about 20 percent of the grain sown area. The planting area of winter wheat has expanded from areas with an altitude of less than 3,000 meters to areas with an altitude of less than 4,100 meters, and the Tibetan Plateau has developed from a historical area of spring wheat into an area where both spring and winter wheat are grown. In 1977, the average yield of winter wheat per mu in the agricultural areas of the valley exceeded 400 jin, and that of bare barley and spring wheat also reached 300 jin per mu.

Certain hydrothermal conditions and soil conditions are the basis of crop growth. The Tibetan Plateau covers a vast area, and the changes of altitude and surface form in different areas are extremely complex. Plateau climate and soil have obvious spatial changes, so the distribution of cultivated land and crops has a large regional. There are two groups of high mountain ranges running east-west and north-south in Tibet, forming the basic framework of the plateau. The vast plateau is distributed between the mountains, and there are many low mountains, hills, lake basins and valley inlaid in the meantime, the overall terrain of the whole region gradually picked up from the southeast to the northwest, the southeast is lower, the west, the north is higher. The majestic Himalayas stand on the southern and western borders of China and India, China and Nepal, China and Tin, China and Bhutan, and China and Pakistan. With a total length of 2,400 kilometers and a mountain width of 200-300 kilometers, and an average elevation of more than 6,000 meters, they constitute a natural barrier to the southern part of the Qinghai-Tibet Plateau. The warm and wet airflow in the Bay of Bengal is blocked by mountains. The climate on the southern slope of the Himalayas is warm and humid, while that on the northern foothills of the Himalayas is warm and cool and dry, forming two different climate regions on the southern and northern slopes. The south side of the Himalayas mountain rivers deep, mountain canyon landform. The valley is more than 3000 meters above sea level, and the climate is warm and humid. The soil types are rich, mainly including mountain yellow soil, mountain brown soil, mountain brown soil and mountain meadow soil, etc. The soil is acidic to neutral, and contains rich humus, high nitrogen content, coarse texture and good permeability. Abundant surface runoff, irrigation conditions are better. However, due to terrain limitations, most of the land cannot be used because the slope is greater than 25 degrees, and most of the land is covered by forests. Arable land is mainly distributed in the valley below 4000 meters, the area is very limited.

Data content: Basic parameter data of dam breach process under different slope conditions Data source: through literature search, classification, consolidation and compilation. Description of data quality: Based on Jiang Xiangang's physical model test on dam breach with different bed slopes, the traceability erosion process of the dam body was analyzed in order to propose a traceability erosion model and explore the influencing factors of the traceability erosion process. In addition, this job attempts to quantify the undercut rate of the breach and the change rate of the downstream slope toe at each time. In order to find the relationship between them and obtain the calculation formula of the downstream slope angle, the calculation of traceability erosion was carried out. This can provide the basis for the calculation and analysis in the later stage of the project.
