雅江干支流河道多断面径流输沙水质参数观测数据图集

本研究提供了2019.7与2020.10两次雅鲁藏布江流域干流及主要支流23个断面的径流、泥沙和水质空间分布调查数据。具体包括：水温、电导率、总溶解性固体物质、pH值、溶解氧、浊度、含沙量、径流量。其中水温、电导率、总溶解性固体物质、pH值、溶解氧等水质参数通过哈希（Hach）EXO-2多参数水质仪进行实时监测。含沙量通过采集20 L水样进行过滤、烘干、称重法进行测定。径流量采用多普勒-M9流量计进行测定。同时，提供了监测断面的采样测量照片。该数据集涵盖雅鲁藏布江流域上、中、下游及主要支流的水质和水沙空间分布数据，为流域水环境要素空间变化与潜在风险点辨识以及流域水土保持综合治理措施的优化提供科学依据。

This study provides survey data on the spatial distribution of runoff, sediment, and water quality collected from 23 monitoring sections in the main stream and major tributaries of the Yarlung Zangbo River Basin during two surveys conducted in July 2019 and October 2020. Specifically, the data includes: water temperature, electrical conductivity, total dissolved solids, pH value, dissolved oxygen, turbidity, sediment concentration, and runoff volume. Among these, water quality parameters such as water temperature, electrical conductivity, total dissolved solids, pH value, and dissolved oxygen were monitored in real-time using Hach EXO-2 multiparameter water quality meters. Sediment concentration was determined by collecting 20 L water samples and using the filtration, drying, and weighing method. Runoff volume was measured using Doppler-M9 flow meters. Additionally, photos of sampling and measurement at the monitoring sections are provided. This dataset covers the spatial distribution data of water quality, water, and sediment in the upper, middle, and lower reaches as well as major tributaries of the Yarlung Zangbo River Basin, providing a scientific basis for the identification of spatial variations of water environment factors and potential risk points, as well as the optimization of comprehensive soil and water conservation measures in the basin.
