摘要:阿尔金山位于青藏高原北缘,以当金山口和车尔臣河上游河谷为界,是塔里木盆地和柴达木盆地的界山,该地区冰川属亚大陆型冰川和极大陆型冰川。冰川边界和长度是冰川的重要参数,其变化可直接反映冰川的进退状态,并间接表征区域的气候变化规律。本数据集基于2016年Landsat OLI遥感影像和SRTM DEM数字高程模型数据,采用人工目视解译和冰川中流线方法获得阿尔金山2016年冰川边界和冰川长度数据。本数据集包含两个数据:1)2016年阿尔金山冰川边界矢量数据;2)2016年阿尔金山冰川长度矢量数据。本数据集反映了阿尔金山2016年冰川边界及长度状态,可作为区域冰川变化和气候变化等研究的基础数据。

Abstract & Keywords
Abstract: TheAltun mountains is located in the northern edge of the Tibet Plateau. It is the boundary of the Tarim Basin and the Qaidam Basin, which is bounded by the Dajinshan pass and the upper reaches of the Qiemo River. Glaciers in the Altun Mountains are subcontinental glaciers and polar continental glaciers. The boundary and length are two vital parameters of one glacier, whose change can directly reflect its advance and retreat, and indirectly characterize the regional climate change. Based on the Landsat OLI images and SRTM DEM, the boundary and glacier length of glaciers in the Altun mountains in 2016 were obtained by means of manual visual interpretation and glacier centerline method. The dataset contains two parts: 1) glacier boundary vector data in the Altun Mountains in 2016; 2) glacier length vector data in the Altun Mountains in 2016. This dataset reflects the boundary and length of glaciers in the Altun Mountains in 2016 and can be used as the basic data of glacier change and regional climate change research.
