英文摘要Highlights What are the main findings? Flash floods exhibit exponential growth, especially in the headwaters of the five major rivers. The seasonal movement trajectory of the center of gravity of flash floods is directional. Soil moisture content and human activities are the predominant drivers of flash flood occurrence. What are the implications of the main findings? This study provides a practical and reproducible blueprint for investigating flood dynamics from both natural and anthropogenic perspectives by integrating interpretable machine learning with Random Forest analyses. The results provide a scientific underpinning for understanding the mechanisms of flash flood generation in High Mountain Asia, advancing monitoring and early-warning research, and informing the implementation of disaster prevention and mitigation strategies.Highlights What are the main findings?

However, the long-term evolution of flash flood patterns over recent decades remains insufficiently understood, particularly in data-scarce high-altitude regions. Using multi-source remote sensing data integrated with historical disaster records and field investigations, this study examined the spatiotemporal evolution and driving factors of flash floods across the Qinghai-Tibet Plateau (QTP). The results indicate that flash floods have increased exponentially, which may be influenced by disaster management policies, with peaks in July-August and frequent occurrences from April to September. The seasonal trajectory of the center of gravity of flash floods from April to September exhibited a clear directional pattern. Regions with the highest disaster density were concentrated in the headwaters of five major rivers, including the Yarlung Zangbo, Jinsha, Nu, Lancang, and Yellow Rivers. Shapley Additive Explanation (SHAP) and Random Forest analyses reveal that soil moisture, anthropogenic intensity, and seasonal runoff variability are the dominant driving factors. With ongoing socioeconomic development, intensified human activities have become a key contributor to the increasing frequency of flash floods. These findings highlight the value of remote sensing-based assessments for flash flood monitoring and early warning and provide scientific support for risk mitigation, loss reduction, and the advancement of water-related targets under the United Nations' Sustainable Development Goals.
