Record the original collection process of glacier, runoff, soil and air microbial samples. 1) Collection of ice and snow microbial samples: wear clean gloves during collection and collect ice and snow into clean self sealing bags. 2) Collection of ice dust microbial samples: insert the hose into the bottom of the ice and snow cave, suck the sediment and melt water into the sampling bottle with a syringe, store them at low temperature and bring them back to the laboratory. Both the sediment and melt water on the top of the ice dust cave are used to extract environmental DNA. 3) Runoff includes ice runoff and glacier front runoff, and the runoff melt water is directly collected into the sampling bottle or water collection bag. 4) Collection of soil in front of Glacier: collect soil samples with shovel, put the soil into clean whirl Pak sampling bag after passing 2mm soil sieve, and then store it at low temperature for subsequent soil DNA extraction. 5) Air membrane sample collection: place the designed sampling device at the sampling point. The lower part of the device is a battery (continuous operation for 48h), and the upper part contains two filter membranes to collect air microorganisms for DNA extraction. 6) for real-time monitoring of physical and chemical properties in Glacier runoff and melt water, use YSI multi parameter water quality instrument to directly put it into the sample to be measured to obtain temperature, do, chlorophyll concentration, etc.

The data includes: zooplankton species list; zooplankton density; microscopy; high-throughput sequencing; complete data; constructing an original data set for lakes on the Qinghai-Tibet Plateau. Zooplankton is an indispensable link in lake water ecological investigation, and it is a link between the system The location of the food web is an important carrier for the material circulation and energy flow of the food web. The systematic investigation and study of the composition and biodiversity of the zooplankton in the lakes on the Qinghai-Tibet Plateau is particularly important for understanding the stability and resilience of the lake ecosystem on the Qinghai-Tibet Plateau. In addition, Zooplankton are very sensitive to environmental changes, and changes in their structure and functional groups can indicate the intensity and magnitude of environmental pressure.

In order to describe the diseases of the main domesticated animals in the Qinghai Tibet Plateau and its surrounding areas, investigate the epidemic situation of the main domestic animals in the Qinghai Tibet Plateau, collect the genetic samples of the resistant and susceptible individuals and the intestinal microbial samples of the main epidemic diseases of the main domestic animals. The data set includes 48 samples of brown cattle in Yili area of Xinjiang, 39 samples of Haidong Mongolian sheep in Qinghai, 32 samples of Qinghai horse, 20 samples of Shangri La yellow cattle in Yunnan and 20 samples of goat. All the samples were fresh feces, and the results of 16S sequencing were obtained after DNA extraction. All the data are original data without any analysis. The purpose of testing these samples is to compare the differences of intestinal microbial species and quantity among different domestic animals in the pan third polar region.

This dataset is the spatial distribution map of the marshes in the source region of the Yellow River near the Zaling Lake-Eling Lake, covering an area of about 21,000 square kilometers. The data set is classified by the Landsat 8 image through an expert decision tree and corrected by manual visual interpretation. The spatial resolution of the image is 30 m, using the WGS 1984 UTM projected coordinate system, and the data format is grid format. The image is divided into five types of land, the land type 1 is “water body”, the land type 2 is “high-cover vegetation”, the land type 3 is “naked land”, and the land type 4 is “low-cover vegetation”, and the land type 5 is For "marsh", low-coverage vegetation and high-coverage vegetation are distinguished by vegetation coverage. The threshold is 0.1 to 0.4 for low-cover vegetation and 0.4 to 1 for high-cover vegetation.
