怒江干流云南段重大泥石流历史暴发事件（1950-2021）

1）怒江干流云南段历史暴发事件的重大泥石流的名称、位置、灾害暴发时间、灾情及事件记录以及数据来源；2）在参考已有文献资料的基础上，基于现场调查访问、遥感解译形成该数据；3）该数据将怒江干流云南段重大泥石流的历史暴发事件次数由原有文献的86次更新为134次，从而形成怒江干流云南段目前最新的可明确具体泥石流沟谷的事件记录，为怒江干流重大泥石流的分布规律、主控因素、演化趋势的研究提供更详实的数据，并可为地方政府的风险防控提供数据支撑。

1) Names, locations, outbreak timestamps, disaster severity, event records, and data sources of historical major debris flow outbreak events along the mainstream of the Nujiang River in Yunnan Province; 2) This dataset was developed based on a review of existing literature, combined with field investigations and interviews, as well as remote sensing interpretation; 3) This dataset revises the count of historical major debris flow outbreak events along the Nujiang River mainstream in Yunnan from 86 reported in previous literature to 134, thereby establishing the most up-to-date event records with clearly identifiable specific debris flow gullies for this segment. It provides more comprehensive and detailed data for studies on the distribution patterns, dominant controlling factors, and evolutionary trends of major debris flows along the Nujiang River mainstream, and offers reliable data support for risk prevention and control efforts by local governments.
