11月份全国自然灾害风险形势如何？多部门研判

Core Insights - The National Disaster Reduction Committee and various ministries have assessed the natural disaster risk situation for November 2025, highlighting multiple risks across different regions of China [1][2]. Summary by Category Low Temperature, Rain, Snow, and Freezing Disaster Risk - In November, four cold air processes are expected to impact China, leading to higher precipitation and lower temperatures in northeastern Inner Mongolia and the northeast region, increasing the risk of low temperature, rain, snow, and freezing disasters [1]. Forest and Grassland Fire Risk - Certain areas, including northern and western Beijing, northern and western Hebei, southern Shanxi, and parts of Zhejiang, Anhui, Fujian, Jiangxi, Shandong, Henan, Hubei, Hunan, Guangdong, and Guangxi, are expected to have a higher risk of forest fires in November, while the overall grassland fire risk remains low [1][2]. Geological Disaster Risk - Regions such as central Hunan, northeastern Guangxi, eastern Chongqing, northern and southern Sichuan, northwestern and northeastern Yunnan, southwestern Shaanxi, central and southern Gansu, and eastern Qinghai are projected to have a higher risk of geological disasters in November [2]. Flood Disaster Risk - Increased rainfall is anticipated in the central and southwestern regions, as well as southeastern Tibet, raising concerns about potential flooding due to continuous rain and localized heavy precipitation. Major rivers in the northeast are expected to experience initial freezing, with the upper reaches of the Yellow River in Inner Mongolia also likely to see initial ice formation by the end of the month [2]. Marine Disaster Risk - One to two typhoons are expected to form in the South China Sea or the northwestern Pacific in early November, with one potentially impacting the South China Sea and nearby coastal areas. Additionally, a significant storm surge and several hazardous wave events are anticipated along the coast during November [2].
