2008年汶川地震后泥石流多时序追踪数据集

本本数据集提供了2008年汶川Ms 8.0级地震后，在青藏高原东侧龙门山区域（中国四川）诱发泥石流的两个追踪数据集。该数据库通过文献综述、震中地区现场调查报告，结合高分辨率遥感影像和广泛的数据收集与处理而获得。 第一个数据集：覆盖892平方公里区域，包含了2008年至2020年的泥石流事件（更新版）。共识别出影响79个流域的186次泥石流。同时收集了89个雨量站的数据以确定震后泥石流爆发的降雨事件。 第二个数据集：是一个震后泥石流防治措施清单，包括流域名称、拦砂坝编号、坐标、建设时间和成功减灾日期。 该数据集可用于泥石流早期预警和工程防治等不同应用，并为相关学科的研究提供宝贵的数据支持。This dataset provides two tracking datasets of debris flows triggered by the 2008 Wenchuan Ms 8.0 earthquake in the Longmenshan region on the eastern side of the Tibetan Plateau (Sichuan, China). This database was developed through literature review, field investigation reports of the epicentral area, combined with high-resolution remote sensing imagery, and extensive data collection and processing. The first dataset covers an area of 892 km², containing updated debris flow events from 2008 to 2020. A total of 186 debris flow events affecting 79 watersheds have been identified. Additionally, data from 89 rainfall stations were collected to determine the rainfall events that triggered post-earthquake debris flows. The second dataset is an inventory of post-earthquake debris flow mitigation measures, including watershed names, check dam identification numbers, coordinates, construction dates, and successful disaster reduction dates. This dataset can be applied to various scenarios such as debris flow early warning and engineering mitigation, and provides valuable data support for research in relevant academic fields.
