摘要:中国西部冰川区对气候变化响应敏感性强,变化幅度大。自中国第二次冰川编目以来,我国缺乏对中国西部地区冰川的系统性调查。本数据集在中国第二次冰川编目数据基础上,利用315景Landsat遥感影像和SRTM等多种数据源,结合ArcGIS、Google Earth等处理软件,通过人工目视解译,完成了2018年中国西部冰川边界的提取、边界的质量检查、面积的不确定分析和冰川属性的更新。结果显示,2018年中国西部现存冰川53238条,总面积为47174.21±19.93km2,面积误差占冰川总面积的±0.04%。在中国第二次冰川编目未完成的藏东南地区,共有冰川13066条,总面积7611.25±4.64km2。本数据集为探讨中国西部冰川变化和冰川对气候变化的响应等相关研究提供数据支撑。

Abstract: The glacier area of West China is more sensitive to climate change response and the magnitude of change varies widely. Since the second glacier inventory in China, there has been a lack of systematic investigation of glacier in West China. Based on the second glacier inventory data of China, this dataset has completed the extraction of glacier boundaries, quality checking of boundaries, uncertainty analysis of area and updating of glacier attributes in West China in 2018 by using various data sources such as 315 Landsat remote sensing images and SRTM, combined with processing software of ArcGIS and Google Earth, and through manual visual interpretation. The results show that 53238 glaciers existed in West China in 2018, with a total area of 47174.21 ± 19.93 km2, area error of ±0.04% of the total glacier area. In southeastern Tibet, where the second glacier inventory in China is not yet complete, there are 13066 glaciers with a total area of 7611.25±4.64km2. This dataset provides data support for studies related to the exploration of glacier changes and glacier response to climate change in West China.
