黄河源地区地表蒸散发数据集（2000-2014）

本数据集覆盖的黄河源地区为16个县的全部县域地区，包括青海省曲麻莱、玛多、达日、久治、甘德、玛沁、兴海、同德、共和、贵南、泽库和河南蒙古族自治县，甘肃省玛曲县，四川省阿坝、红原和若尔盖县。全区覆盖面积为132,658 km&sup2。黄河源地区地表蒸散发数据集（2000-2014）是在MODIS 16A2蒸散发（Evapotranspiration, ET）月数据产品基础上开发得到。该数据集由4部分内容组成，它们分别为：（1）研究区边界数据（.shp格式）；（2）2000-2014年历年和15年平均的黄河源地区1 km的蒸散发栅格数据（16组数据文件，.tif格式）；（3）2000-2014年黄河源地区多年平均的四季蒸散发1 km栅格空间分布数据（4组数据文件，.tif格式）；（4）2000-2014年黄河源地区历年各月的蒸散发统计数据（.xlsx格式）。数据集由88个数据文件组成，数据量为30.3 MB（压缩为1个文件，5.37 MB）。该数据集的分析研究成果发表在《地理学报》2018年第73卷第11期。

The Yellow River Source Region covered by this dataset refers to the entire administrative areas of 16 counties, including Qumalai, Maduo, Dari, Jiuzhi, Gande, Maqên, Xinghai, Tongde, Gonghe, Guinan, Zêkog, and Henan Mongol Autonomous County of Qinghai Province, Maqu County of Gansu Province, as well as Aba, Hongyuan, and Zoigê Counties of Sichuan Province. The total coverage area of this region is 132,658 km². The surface evapotranspiration dataset of the Yellow River Source Region (2000–2014) was developed based on the MODIS 16A2 monthly evapotranspiration (ET) product. This dataset consists of four components: (1) Boundary data of the study area (in .shp format); (2) 1-kilometer-resolution evapotranspiration raster data of the Yellow River Source Region for each year from 2000 to 2014 and the 15-year average (16 data files in total, in .tif format); (3) 1-kilometer-resolution spatial distribution raster data of multi-year average seasonal evapotranspiration in the Yellow River Source Region from 2000 to 2014 (4 data files in total, in .tif format); (4) Monthly evapotranspiration statistical data of the Yellow River Source Region for each month from 2000 to 2014 (in .xlsx format). The dataset contains 88 data files in total, with a total size of 30.3 MB (compressed into a single file of 5.37 MB). The analytical research results of this dataset were published in *Acta Geographica Sinica*, Volume 73, Issue 11, 2018.
