From September 3 to September 9, 2020, groundwater and surface water were collected in the upper reaches of Nujiang River Basin (i.e. Naqu basin in Nujiang River source area), and the samples were immediately put into 100 ml high density polyethylene (HDPE) bottles. 18O and D are analyzed and tested by liquid water isotope analyzer (picarro l2140-i, USA), and the stable isotope ratio is expressed by the thousand difference relative to Vienna "standard average seawater" (VSMOW). δ 18O and δ The analysis error of D is ± 0.1 ‰ and ± 1 ‰ respectively. It provides basic data support for subsequent analysis of groundwater source analysis in Naqu basin.

In order to explore the inorganic hydrochemical characteristics of Naqu basin, river water and groundwater were collected in Naqu basin in September 2020 and September 2021. Collect river water and groundwater with 550ml plastic bottles on site. The main anions and anions (ca2+, na+, mg2+, k+, so42- and cl-) are measured with an ion chromatograph (metrohm ecoic, Switzerland), with a measurement accuracy of 1 μ G/l. Bicarbonate (hco3-) is titrated with acid-base indicator and determined with 50ml acid burette. The purpose is to reveal the inorganic hydrochemical characteristics of water bodies in Naqu basin and provide data support for the analysis of groundwater recharge sources in Naqu basin.

This data is the seepage pressure monitoring data in the fracture area of Baige landslide in Jinsha River. The main purpose is to determine the impact of groundwater on Baige landslide. Four osmometers are arranged in combination with the site geological conditions. The field manual monitoring method is adopted, and the data is processed with Excel software. Combined with the analysis of rainfall monitoring data, the change process of groundwater level has little to do with rainfall. The measured values of the four osmometers are within ± 5kpa (0.5m water head). By 2020, the osmolality of the four boreholes will basically disappear. That is, there is little relationship between landslide and seepage pressure. Through the analysis of the data, the direct impact of groundwater on the instability of Baige landslide is excluded, which provides technical support for the stability evaluation and landslide treatment of Baige landslide.
