亚洲主要河流水化学及环境因子数据集

本数据集系统整合了亚洲主要河流流域的水化学和环境因子信息，全面涵盖了河水中主要阳离子（Ca²⁺、Mg²⁺、Na⁺、K⁺）及阴离子（HCO₃⁻、SO₄²⁻、Cl⁻、NO₃⁻）等浓度指标，以及pH值等水体化学特征参数。同时，数据集在流域尺度上整合了不同流域的年平均径流、温度、高程、坡度、降水量、植被类型等关键环境因子，并提供主要岩性和土壤厚度等地质与土壤特征信息，以全面反映影响河流水化学过程的主要控制因素。本数据集为亚洲主要河流流域间的对比研究以及风化、侵蚀、水质过程等科学分析提供了统一、空间化且可量化的数据支撑。(协议共享)This dataset systematically integrates hydrochemical and environmental variable data from major river basins across Asia. It comprehensively covers concentration indicators including major cations (Ca²⁺, Mg²⁺, Na⁺, K⁺) and anions (HCO₃⁻, SO₄²⁻, Cl⁻, NO₃⁻) in river water, alongside aquatic hydrochemical characteristic parameters such as pH value. At the basin scale, the dataset further integrates key environmental variables from individual basins, namely annual average runoff, temperature, elevation, slope, precipitation, vegetation type and other relevant metrics, and provides geological and soil characteristic information including dominant lithology and soil thickness, to fully reveal the primary controlling factors governing river hydrochemical processes. This dataset offers unified, spatially explicit and quantifiable data support for comparative studies among major Asian river basins, as well as scientific analyses of weathering, erosion, water quality dynamics and related research topics.
