Dataset of soil water erosion modulus with 30 m resolution in 11 watersheds of Qinghai (2018)

1) The data includes the soil erosion modulus of 11 watersheds with a resolution of 30 m in the year of 2017 in Qinhai. 2)Based on the surface layer of rainfall erosivity R, soil erodibility K, slope length factor LS, vegetation coverage FVC, and rotation sampling survey unit, the Chinese soil erosion model (CSLE) was used to calculate soil erosin modulus in 11 watersheds respectively. Through spatial data processing (including chart linking and transformation, vector-grid conversion, and resampling), R, K, LS factors were calculated from the regional thematic map of rainfall erosivity, soil erodibility, and DEM. By half-month FVC, NPV, half-month rainfall erosivity data, we calculated the value of B factors in each sampling watershed. The value of E factor was calculated based on the remote sensing interpretation result and engineering measure factor table. The value of tillage factor T was obtained from tillage zoning map and tillage measure table. And then the soil erosion modulus in each sampling watershed was calculated by the equation: A=R•K•LS•B•E•T. The selection of 11 watersheds was based on the layout of sampling survey in pan-third polar region. 3) Compared with the data of soil erosion intensity in the same region in the same year, there is no significant difference and the data quality is good.4) the data of soil erosion modulus is of great significance for studying the present situation of soil erosion in Pan third polar region, and it is also crucial for the implementation of the development policy of the Silk Road Economic Belt and the 21st-Century Maritime Silk Road.

Investigation report on soil salinization around Aral Sea

According to the schedule of the project implementation plan and commissioned by the project team management committee, the Xinjiang Institute of Ecology and Geography of the Chinese Academy of Sciences organized a team of 6 people to carry out a field investigation in the Aral Sea from November 15 to November 26 in view of the desertification, salinization and vegetation construction of the surrounding land. The history, current situation, harnessing work, achievements and pressing problems of soil desertification and salinization around the Aral Sea were preliminarily understood. Sampling of vegetation and soil was carried out, and the technical idea to solve the problem was put forward, that is, planting Halophytes in brackish and saline groundwater to realize rapid vegetation construction in saline-alkali land. Through on-the-spot investigation, the investigation group believed that the implementation of vegetation construction in saline-alkali land should mainly focus on halophytes and local tree species. According to the distribution law of local halophytes and the characteristics of main constructive species in saline-alkali land, combined with the climatic conditions of the implementation site, seven halophytes, such as Salt-eared Tree, should be selected for planting demonstration. After the investigation, the investigation group put forward three specific suggestions on vegetation construction in saline-alkali land.

Measurement data from 26 crustal displacement observation stations of Qilian mountain (2017-2018)

High-frequency continuous GPS observation can effectively monitor the kinematics of crustal deformation. The Qilian Mountains region is an important constraint boundary of the northeastern margin of the Qinghai-Tibet Plateau. The study of this region can provide important implications for the dynamic process of the growth and uplift of the Tibetan Plateau and the internal deformation of the Tibetan Plateau. At the local level, it can be discussed whether there is creepage in the Haiyuan fault and the movement mode of the northeastern margin of the Qinghai-Tibet Plateau. The data comes from 26 fixed stations set up by the research group in the Qilian Mountain area. The site selection requirements are strict, and the high-frequency continuous GPS receiver is Provided by trimble, the data quality is good, the data can be applied not only to geodynamic research, but also to related earth science research such as meteorological precipitation.

Fish collection dataset of the Tibetan Lakes in 2018

In May and September 2018, fish in Tibetan lakes were collected by net-catching and electric-catching methods. The sampling range from east to west can be roughly summarized into three areas: the Qiangtang Plateau in northern Tibet, southern Tibet and the angle between Kunlun Mountains and Karakoram Mountains. A total of 27 lakes have captured fish. The specimens include more than 2,000 specimens of the genus Triplophysa and more than 600 specimens of subfamily Schizothoracinae. This work is a part of the project of “Building Methods for Detection of Aquatic Organisms in the Lake System of the Qinghai-Tibet Plateau”, using traditional fish survey data to generate a list of species in the lake system, which will then be used to combine multiple lakes in Medog and the plateaus. High-throughput molecular data acquired from the system's environmental water samples and tested for visual parameters (lake size, isolation, geographic location, and spectral characteristics) that can be used to predict aquatic biodiversity.

Slope data of economic corridors along Silk Road

Slope data of economic corridors in Silk Road can reflect the degree of steepness of the surface units of the six major economic corridors, the unit is degree (°). The spatial resolution of the data is 0.016 degrees, which is about 1.8km. The longitude range is 12.09°E-180°, and the latitude range is 10.99°S-90°N. The source is derived from the Global Relief Model built by the National Oceanic and Atmospheric Administration of the United States (NOAA). The range is cut by the border of the Silk Road. This data is one of the basic data necessary to assess the risks of natural disasters (including debris flows, landslides, flash floods, etc.) in the six economic corridors. The application frequency will be high and the prospects will be broad.

Blood samples collection of domestic animals in Pamir Plateau(2018)

In the year of 2018, we collected the samples at Taxkorgan county, Kashgar district, the Xinjiang Uygur Autonomous Region, northwestern China. Taxkorgan county is where the Pamir Plateau located in China. Nearly all this county is on the plateau. The average elevation of this county is more the 4000 m above the sea level. And the lowest part of the county is 3100 m above the sea level. In total, 204 samples were collected in Pamir Plateau this time. The samples collected from several different species which including cattle, yak, sheep, goat, donkey, horse and chicken. Each samples have 3-4 repetitions. For each animal, we recorded the id number, species, sex, date of sample collection, GPS coordination and elevation. Also three mateched images, i.e. from head, hoof or feet and whole body, were took for each animal. All the samples taken from the animal are the blood samples. They were keep into the refrigerator until they were finally tranfered and stored in the germplasm recourses bank.

Fossil specimens of Cenozoic mammal from Tibetan Plateau and surrounding area

This dataset comprises fossil specimens of Cenozoic mammal collected from Tibetan Plateau and surrounding area, such as Suerkal Basin in A-erh-chin Mountains, Tabenbuluk in Gansu Province, during 2018-04-01 to 2018-10-01. Most of the specimens were collected in surface of section, part were excavated from shallow strata. All of the specimens were sent to Institute of Vertebrate Paleontology and Paleoanthropology, Chinese Academy of Sciences, cleaned by technician and photographed with digital camera. The specimens are well-preserved and can be easily observed on important characters of the individuals they belong to. The specimens of this data set are all new ones unstudied, and very important for research on mammalian evolution and reconstruction of paleoecology and paleoenvironment in Tibetan Plateau and surrounding area.
