西藏“一江两河”流域农业集中区水体常规指标及重金属含量（2019-2024）

数据集主要包括西藏“一江两河”流域农业集中区水体常规指标（水温、pH、DO、TDS、盐度）和22种金属元素（Pb、As、Se、Hg、Cd、Pb、Zn、Cu等）指标，覆盖年份在2019-2024之间，水样类型覆盖了西藏“一江两河”流域农业集中区的地下水、地表灌溉水和河流地表水。地下水采样点来自设施大棚地下井，地表灌溉水主要来自耕地灌溉沟渠，河流地表水主要来自雅鲁藏布江。水体常规指标采用便携式水质参数仪现场测定，金属元素采用ICP-OES/MS分析测定，所有数据均经过标准物质比对及重复测量验证。数据集为评估雅鲁藏布江流域农业集中区的水体质量、环境健康及农业可持续性提供了重要的科学依据。

This dataset primarily covers conventional water quality indicators (water temperature, pH, dissolved oxygen (DO), total dissolved solids (TDS), salinity) and 22 metal element indicators (Pb, As, Se, Hg, Cd, Pb, Zn, Cu, etc.) from the agricultural concentrated area of the "One River, Two Tributaries" basin in Tibet, with a temporal coverage from 2019 to 2024. The water sample types include groundwater, surface irrigation water and fluvial surface water in the aforementioned region. Groundwater sampling sites are derived from underground wells in protected greenhouses, surface irrigation water mainly originates from farmland irrigation ditches, and fluvial surface water is primarily sourced from the Yarlung Zangbo River. Conventional water quality indicators were measured in-situ using a portable water quality parameter analyzer, while metal elements were determined via ICP-OES/MS analysis. All data were validated through certified reference material comparisons and replicate measurements. This dataset provides critical scientific evidence for evaluating water quality, environmental health and agricultural sustainability in the agricultural concentrated area of the Yarlung Zangbo River basin.
