摘要:三江源地区 (89°45'–102°23'E, 31°39'–36°12'N) 位于青藏高原中东部和青海省南部,是我国重要的水源涵养区和生态环境保护关键地区,发育在该地区的冰川是长江、黄河和澜沧江(境外称湄公河)的重要水源补给。基于Landsat TM/OLI遥感影像数据和ASTER GDEM数据,采用波段比值法并结合人工目视修订获得了该地区2000年、2010年和2019年冰川边界矢量数据,并给出了各条冰川的名称、所在山系和流域、面积、高程及遥感影像数据源等信息。本数据集包括三江源地区三期冰川边界矢量数据和2000–2019年各条冰川的面积变化数据,可作为三江源地区冰川变化和冰川水资源评估等研究的基础数据。

Abstract & Keywords
Abstract: The Three-River Headwaters (TRH) region (89°45'–102°23'E, 31°39'–36°12'N), located in the southern part of Qinghai Province in China and on the central-eastern part of the Tibetan Plateau, is an important water conservation area and the key area for eco-environment protection in China. The glaciers located in this region are important water supply for the Yangtze, Yellow, and Mekong rivers. Based on ASTER GDEM and Landsat TM/ OLI images acquired in 2000s, 2010s, and 2019, the outlines of individual glaciers in the TRH region were obtained by using the band ratio method combined with manual revision. Meanwhile, some properties of each glacier including name, area, elevation, mountain, drainage basin and remote sensing imagery adopted were provided. This dataset is composed of the vectorized data of glacier outlines in 2000s, 2010s and 2019 and an excel table containing the change information of individual glacier area in 2000—2019, which can be used as the basic data for research on glacier changes, the assessment of glacial water resources in the TRH region.
