The Map of Permafrost on the Qinghai-Tibet Plateau (1:3,000,000) (Shude Li and Guodong Cheng, 1996) was made by the State Key Laboratory of Frozen Soil Engineering, LIGG, CAS (currently called the Cold and Arid Regions Environmental and Engineering Research Institute, Chinese Academy of Sciences). It was based on first-hand information from the study of frozen soil and previous research papers and literature. By detailed study and consultation of aerial photographs, satellite images, the Permafrost Map along the Qinghai-Tibet Highway (1:600,000) (Boliang Tong, et al., 1983), Geomorphological Map of the Qilian Mountains (1:1,000,000) (Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences, 1985), Natural Landscape Map of Qinghai-Tibetan Plateau (1:3,000,000) (Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences, 1990), Quaternary Glacial Distribution Map of the Qinghai-Tibetan Plateau (1:3,000,000) (Bingyuan Li and Jijun Li, 1991), Frozen Soil Remote Sensing Map of the Western Channel Project of the South-North Water Diversion in the Region of the Tongtian-Yalong Rivers (1:500,000) (Lanzhou Institute of Glaciology and Cryopedology, Chinese Academy of Sciences, 1995), and Map of Snow, Ice, Frozen Ground in China (1:4,000,000) (Yafeng Shi and Desheng Mi, 1988), with editing on 1,000,000 aerial survey topographic maps, and the 1:3,000,000 Map of Permafrost on the Qinghai-Tibetan Plateau was then generated. It was later digitized by Zhuotong Nan of the Cold and Arid Regions Environmental and Engineering Research Institute, Chinese Academy of Sciences. The data include: 1) Digitized distribution map of frozen soil on the Qinghai-Tibetan Plateau 2) Scanned map of frozen soil map on the Qinghai-Tibetan Plateau The types of frozen soil in the digitized frozen soil map include: 0. Seasonally frozen ground; seasonal frozen soil 1. Permafrost 2. Island permafrost; 3. Continuous permafrost;

Spatial distribution maps of lakes over the Tibetan Plateau (1995-2015)

This data set contains 5 data entities. The spatial distribution data of the lakes on the Tibetan Plateau extracted from Landsat images are used, and the time range is from September to November in 1995, 2000, 2005, 2010 and 2015. The data are made jointly by the Third Pole Environment Database and the Geospatial Data Cloud. The object-oriented method is used for lake extraction. (1) Data preprocessing occurs first. Because this paper only uses the first 7 wave bands of Landsat 8 data, band synthesis is carried out for 1-7 wave bands, and the influence of cloud cover on lake extraction is examined. The data are replaced if the influence is too great. (2) Multiscale segmentation of images is performed in eCognition. Because the spectral characteristics of the lake are uniform, spectral segmentation is used again on this basis. (3) The average characteristics of the 5, 6, and 7 bands (Brigh-567) are used for preliminary water extraction, and for some unextracted lakes, NDWI is used for supplementary extraction. (4) At this time, some shadows remain mistakenly extracted, and most of them can be excluded using NDWI<0.05. At the same time, based on the actual situation, the shadows can be eliminated using the value of the first band. (5) To ensure the accuracy, manually check the unextracted independent lake and the mistakenly extracted object and manually modify it. (6) On this basis, use NDWI>0 for the second extraction around the extracted water body and define the edge of the lake. (7) Check again, then merge the objects and export the results. The data effectively remove the influence of mountain shadows, clouds and cloud shadows, snow cover, glaciers and other non-water objects. The lake boundary is accurate and clear, and the error is controlled within a pixel. The accuracy requirement is 30 meters, which is a pixel.

This data set includes the biomass and photosynthesis observational data of the highland spring barley experimental plot at the Lhasa Farm Experimental Station and the meteorological data observationally obtained at the Damxung Grass Experimental Station. The time range is 2006-2009. Biomass observation method: The sampling area of each sample is 25 cm*25 cm. Photosynthetic data observation: The instrument is a LiCor-6400. The biomass data are manually entered according to the record book. The photosynthetic data are automatically recorded by the instrument. The average wind speed, prevailing wind direction, temperature, atmospheric pressure and relative humidity in the daily values of meteorological data are averaged over half-hour data.
