羌塘高原1:25万土地覆被现状图（2012）

通过野外实地调研羌塘高原土地覆被类型，定义羌塘高原土地覆被分类系统，包括高寒荒漠、高寒草原、高寒草甸、高寒稀疏植被、湖泊与河流、冰川及常年积雪、裸地等类型。基于MODIS遥感影像，采用面向对象的分类方法，解译了2015年羌塘高原寒旱核心区土地覆被数据，并结合专家知识、人工目视解译和2012年9月~10月野外土地覆被类型调查样点，对初步提取结果进行全面的修正。在数据集的基础上，编制了羌塘高原25万比例尺的土地覆被现状图。

Through field surveys of land cover types in the Qiangtang Plateau, a land cover classification system for the Qiangtang Plateau was established, including categories such as alpine desert, alpine steppe, alpine meadow, alpine sparse vegetation, lakes and rivers, glaciers and permanent snow cover, and bare land. Based on MODIS remote sensing images and using the object-oriented classification method, land cover data of the cold-arid core area of the Qiangtang Plateau in 2015 were interpreted. The preliminary extraction results were comprehensively revised by combining expert knowledge, manual visual interpretation, and field survey samples of land cover types collected from September to October 2012. On the basis of this dataset, a current land cover map of the Qiangtang Plateau at a scale of 1:250,000 was compiled.
