摘要:以青藏高原为核心的中国西部地区,地理范围为26°N~55°N,65°E~105°E,区域范围包含喜马拉雅山、横断山、天山及阿尔泰山等。区域内冰湖分布密集,不仅能够真实地记录气候与冰川的变化状况,而且对于区域水资源具有十分重要的作用。本数据集在综合中国第二次冰川编目数据、云量覆盖度低于10%的Landsat OLI等多种数据的基础上,结合ArcGIS、ENVI及Google Earth等处理软件,通过人工目视解译的方法提取冰川边界10 km范围内的冰湖边界,并对解译后的数据进行统一的属性添加、质量检验与精度验证。本数据集由两部分组成,分别为使用冰川编目数据生成的冰湖分布区矢量文件和2015年中国西部冰湖编目数据集。不仅能够作为中国西部冰湖–冰川耦合关系、水资源利用与管理等相关研究的参考数据,还可以作为区域气候变化与冰冻圈等相关研究的基础数据。

Abstract & Keywords
Abstract: The West China region with the Tibetan Plateau as its core has a geographical range of 26°N~46°N,62°E~105°E, with Himalayas, Hengduan mountain, Tienshan, Altai and other mountains and plateaus involved. With the high concentration of glacial lakes in this region, it can record the changes of climate and glacier, but play a significant role in regional water resources as well. Integrated the second glacier inventory data and Landsat OLI remote sensing data which cloud cover is less than 10%, this dataset combined the processing software of ArcGIS, ENVI and Google Earth to extract glacial lake boundary within 10km range of glacier boundary through manual visual interpretation, and performed unified attribute addition, quality inspection and precision verification after it. The dataset consists of vector files of glacial lake distribution region derived from glacier inventory data and the glacial lake inventory of West China in 2015. It can not only be the reference data for the study of the coupling relationship between glacial lake and glacier, water resource usage and management in West China, but also be used as the basic data of regional climate and cryosphere change.
Keywords: glacial lake inventory; West China; 2015
