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。坡度低于1°或高于15°的网格被排除在外，因为根据我们之前的研究和实地调查，在这些坡度上很少发现 RTS。其余网格中的RTS由第一作者发现并绘制草图，然后由至少另外两名有经验的作者进行检查。一旦确定了一个RTS，就会为其分配一个唯一的编号，并根据其起因进行分类，如紧邻河流（R）、受湖泊侵蚀（L）以及发生活动层剥离滑动之后。", "ds_source": "

This dataset contain the retrogressive thaw slump (RTS) inventory in permafrost region of the Qinghai–Tibet Plateau (QTP) based on field investigations and the manual interpretation of the Gaofen-1 and Gaofen-2 images. RTSs were visually detected based on the presence of recently exposed sediments, poorly developed vegetation, and distinct headwalls. To avoid misdelineation of the RTS, the entire permafrost region of the QTP was divided into a large number of grids measuring 5 × 5 km each. Grids with slope degrees below 1° or higher than 15° were excluded because RTSs are rarely found at these slopes according to our previous study and field investigations. RTSs in the remaining grids were detected and sketched by the first author and then examined by at least two other experienced authors. Once a RTS was identified, it was assigned a unique number and classified based on its initiation such as next to a river (R), by lake erosion (L), and after the occurrence of active-layer detachment slide.
