Retrogressive thaw slumps on the Tibetan Plateau from 1986 to 2020

The degradation of permafrost on the Tibetan Plateau (TP) exacerbates the expansion of retrogressive thaw slumps (RTSs), posing a threat to the stability of infrastructure. Based on time-series Landsat images, we used a combination of machine learning automatic classification and manual delineation to identify 3537 RTSs in the permafrost region of TP from 1986 to 2020, the data also provided detailed information on RTSs area and annual disturbance time.青藏高原（Tibetan Plateau, TP）多年冻土的退化加剧了热融滑塌（retrogressive thaw slumps, RTSs）的扩张，对基础设施稳定性构成威胁。本研究基于时间序列Landsat影像，结合机器学习自动分类与人工勾绘的方法，在1986年至2020年间识别出青藏高原多年冻土区内的3537处热融滑塌，该数据集还包含了热融滑塌的面积与年度扰动时间等详细信息。
