天山-帕米尔冻融滑坡灾害点（2022-2023）

本滑坡数据集为2022-2023年间基于该区域Google Earth开源遥感影像资料解译，数据包括了滑坡面积、周长、经纬度信息。数据解译过程为：首先结合前期调研搜集的区域滑坡文献资料，分析滑坡的形态特征和色彩、图斑特征，建立滑坡在遥感影像图上的解译标准，在Google Earth软件中创建矢量图层并设置好地理坐标，采用人工目视解译的方法对天山山脉及帕米尔高原地区区域内的滑坡逐个解译，并组织资深研究人员核对解译结果，最后进行了部分现场验证。最终记录冻融相关滑坡灾害点973处，总面积约为2209.02平方公里。解译结果为了解天山山脉及帕米尔高原地区滑坡地理分布特点提供了研究基础，也使野外考察研究更具有方向性。

This landslide dataset was compiled via interpretation of open-source remote sensing imagery from Google Earth for the years 2022–2023. The dataset contains records of landslide area, perimeter, latitude and longitude coordinates. The interpretation workflow was as follows: First, drawing on regional landslide literature collected during preliminary surveys, we analyzed the morphological, color and patch features of landslides, and established standardized interpretation criteria for landslides on remote sensing imagery. We then created vector layers and configured geographic coordinate systems within the Google Earth software, and performed manual visual interpretation for every landslide within the Tianshan Mountains and Pamir Plateau region. Subsequently, senior researchers were organized to cross-check the interpretation results, and partial on-site validations were conducted in the final stage. Ultimately, 973 freeze-thaw related landslide hazard points were documented, with a combined total area of approximately 2209.02 square kilometers. These interpretation results provide a foundational research resource for investigating the geographic distribution patterns of landslides in the Tianshan Mountains and Pamir Plateau, and also provide clear direction for subsequent field surveys and studies.
