摘要

山洪灾害是中国最为严重的自然灾害，严重影响了中国社会经济发展。在第一次全国自然灾害风险普查的背景下，对山洪灾害多发区域进行区划评估，有助于区域山洪灾害风险管控和重点隐患排查工作的开展。采用了《洪水风险区划及防治区划编制技术要求》中对于山地洪水防治区划的推荐方法，并在此基础上进行了算法改进，依托山洪灾害调查评价成果，对云南省山地洪水威胁区防治区划进行了计算分析，进而得出了云南全省各级山地洪水威胁区防治区划的面积及分布情况。结果表明，云南省山地洪水重点、中等、一般防治区分别占行政区划面积的7.73%、4.99%和87.28%,重点防治区在云南省中部和东北部地区分布较为密集。并且本次采用的计算方法可随着山洪灾害调查评价成果的更新进行快速迭代，可为各地山地洪水防治工作提供相应的支撑。

Abstract

The flash flood disaster represents one of the most severe natural disasters in China, significantly impacting the country's social and economic development. From 2020 to 2022, the State Council conducted the first National Survey on Natural Disaster Risks, with a national general survey focusing on flood and drought disaster risks being a crucial component of this initiative. In accordance with the requirements of this survey, we utilized the calculation method ology outlined in “Technical Requirements for the Preparation of Flood Risk Regionalization and Prevention and Control Regionalization.” Building upon this foundation, we refined the calculation method for prevention and control zoning specifically within mountain flood threat areas. Utilizing data derived from the result of flash flood disaster investigation and evaluation, we calculated the prevention and control zoning for areas threatened by flash floods in Yunnan Province. The result indicate that key, medium, and general prevention and control zoning for flash floods in Yunnan account for 7.73%, 4.99%, and 87.28% of the total area respectively. Notably, the key prevention and control zoning for the flash flood are predominantly concentrated in central and northeastern regions of Yunnan Province. The zoning assessment of areas susceptible to flash flood disasters facilitates regional risk management strategies as well as targeted investigations into critical hidden dangers. Furthermore, the calculation method employed in this study allows for rapid iteration alongside updates from ongoing investigation and evaluation into flash flood disasters, thereby providing essential support for effective prevention and control measures across various locations.
