1998-2017年青藏高原地区水资源（径流）时空分布后处理产品

通过国家气象信息中心、水文年鉴、中国统计年鉴及中国科学院地理科学与资源研究所等单位收集了水文气象及、土地利用及DEM等基础数据。采用具有自主知识产权的分布式时变增益水文模型进行建模，以100平方千米阈值将青藏高原划分成10937个子流域。在黑河、雅鲁藏布江、长江源、黄河源、雅砻江、岷江、澜沧江流域选取了14个流量站观测日流量数据对模型进行了拟定与验证。日尺度纳西效率系数达到0.7以上相关系数达到0.8以上。模型模拟出1998-2017年水循环过程，给出全青藏高原空间0.01度日尺度径流时空分布。

Basic data including hydrometeorological data, land use data and DEM were collected from the National Meteorological Information Center, Hydrological Yearbooks, China Statistical Yearbook, and the Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences, among other institutions. A distributed time-variant gain hydrological model with independent intellectual property rights was adopted for modeling. The Qinghai-Tibet Plateau was divided into 10,937 sub-basins with a threshold of 100 square kilometers. Fourteen daily streamflow observation stations were selected from the basins of the Heihe River, Yarlung Zangbo River, source regions of the Yangtze River and Yellow River, Yalong River, Minjiang River, and Lancang River for model calibration and validation. The daily-scale Nash-Sutcliffe Efficiency (NSE) coefficient exceeded 0.7, and the correlation coefficient reached above 0.8. The model simulated the water cycle process over the period 1998–2017, and provided the spatial-temporal distribution of daily-scale runoff with a 0.01° spatial resolution across the entire Qinghai-Tibet Plateau.
