To explore inorganic hydrochemical characteristics of the upper Yarlung Zangbo River, water samples were collected from the main stream and different tributaries in this region in August 2020. The water was collected with 100mL polyethylene (PE) plastic bottle, and the basic physical and chemical parameters such as pH value (±0.2) and dissolved oxygen (±1%) of the sampling site were measured by multi -parameter water quality monitor (YSI-EX02,USA).,and HCO3- concentration was titrated with 0.025mol/L HCl.The concentrations of Na+, K+, Ca2+, Mg2+, SO42-, NO3- and Cl- ions were analyzed and determined by ion chromatograph (Shenhan CIC-D160, China) in the laboratory. Using Gibbs model, correlation analysis and principal component analysis method, analyzed the one main ion concentration changes, chemical composition characteristics, analytical, and the ion source was designed to reveal inorganic water chemical characteristics of The Tibet plateau glacier melt water runoff, and for plateau typical river water and changing trend forecast provides the basis.

(1) This data set contains a variety of heavy metal concentration data in multi-media, which is of great significance to explore the internal relationship between heavy metal pollution evaluation and heavy metal distribution in water; (2) The data source is to collect water, soil, crops and other samples from Huangshui River and its tributaries on the spot, send them to the laboratory for pretreatment, and complete the detection with relevant instruments; (3) The data set is of high quality and the sampling process is standardized. After collection, the samples are quickly stored in the - 4 ℃ refrigerator and sent to the laboratory for testing. The testing process is strictly carried out in accordance with relevant standards; (4) The data set can be mainly used for ecological risk and health risk assessment, spatial distribution analysis, source analysis, correlation analysis and so on.
