长江和黄河源区历史阶段径流总量和冰冻圈融水径流逐月数据集

本数据集为长江和黄河源区历史阶段径流总量和冰冻圈融水径流逐月数据集，采用基于流域地貌特征的冰冻圈区域分布式水文模型GBEHM模拟获取，数据集变量包含逐月总径流、融雪径流与冰川径流，数据时间范围为1960-2019年，空间分辨率为2.5 km/3 km。模型输入数据包含气象驱动、植被、土壤、土地利用等，模拟结果能够较好反映长江和黄河源区水文要素的时空变异特征。数据集可进一步用于长江和黄河源区冰冻圈生态水文相关研究，为长江大保护、黄河流域生态保护和高质量发展等国家重大战略提供科学支撑。

This dataset is a monthly dataset of historical total runoff and cryospheric meltwater runoff in the source regions of the Yangtze River and the Yellow River. It was simulated using the GBEHM, a distributed hydrological model for cryospheric regions based on watershed geomorphic characteristics. The variables included in the dataset are monthly total runoff, snowmelt runoff, and glacial melt runoff. The temporal coverage of the dataset spans from 1960 to 2019, with a spatial resolution of 2.5 km/3 km. The model input data includes meteorological forcing, vegetation, soil, land use, and other related datasets. The simulation results can effectively reflect the spatiotemporal variation characteristics of hydrological elements in the source regions of the Yangtze River and the Yellow River. This dataset can be further used for research related to cryospheric eco-hydrology in the source regions of the Yangtze River and the Yellow River, providing scientific support for major national strategies such as the Great Protection of the Yangtze River and the Ecological Protection and High-quality Development of the Yellow River Basin.
