青藏高原多年冻土区倒退融化坍落度（RTS）存量数据集

该数据集包含基于野外调查和对高分一号和高分二号图像的人工判读的青藏高原（QTP）冻土区逆冲融雪坍塌（RTS）清单。根据新近裸露的沉积物、发育不良的植被和明显的顶壁的存在，可目测出区域冻土层。为避免对RTS的错误划分，将QTP的整个永久冻土区划分为大量网格，每个网格的大小为5×5千米。...

This dataset contains an inventory of retrogressive thaw slumps (RTS) in the permafrost regions of the Qinghai-Tibet Plateau (QTP), compiled based on field surveys and manual interpretation of Gaofen-1 (GF-1) and Gaofen-2 (GF-2) high-resolution satellite images. Permafrost distribution can be visually identified based on the presence of newly exposed sediments, stunted vegetation, and distinct headwalls. To avoid misclassification of RTS, the entire permafrost zone of the QTP was divided into numerous grids with a size of 5×5 km...
