过去40年黄河源和祁连山区水量-能量平衡数据集（1981-2020）

本数据集为过去40年黄河源和祁连山区水量平衡（降水、蒸散发、径流、土壤液态含水量）、能量平衡（短波辐射、感热、潜热和表层土壤温度）数据集。初始数据源为ERA5-Land月平均数据，通过时间聚合累积/平均到年尺度。数据的时间范围为1981-2020年，空间范围为88.5°E – 104.5°E、32°N - 43°N，空间分辨率0.1°。数据集可进一步用于黄河源区与祁连山区生态-水文过程相关研究，为“山水林田湖草”系统优化调配提供科学依据。

This dataset provides 40-year water balance and energy balance data for the source region of the Yellow River and the Qilian Mountains. The water balance variables include precipitation, evapotranspiration, runoff, and soil liquid water content, while the energy balance variables include shortwave radiation, sensible heat, latent heat, and surface soil temperature.
The initial data source is the monthly-averaged ERA5-Land dataset, which is processed via temporal aggregation to generate annual-scale cumulative or averaged values.
The dataset covers the time period from 1981 to 2020, with a spatial scope of 88.5°E–104.5°E and 32°N–43°N, and a spatial resolution of 0.1°.
This dataset can be further applied to studies on eco-hydrological processes in the source region of the Yellow River and the Qilian Mountains, providing scientific support for the optimal allocation of the mountains, waters, forests, farmlands, lakes and grasslands ecosystem.
