摘要
Abstract
Guangxi is a typical karst landform region,frequently hit by flash floods with high destructive power.In re-cent years,Guangxi has established monitoring and early-warning systems,implemented flood control projects in key flash flood-prone gullies,and promoted the construction of grassroots community-based monitoring and preven-tion systems,which have led to the initial formation of a specialized and community-integrated defense system,achieving significant disaster prevention outcomes.From 2020 to 2024,it recorded zero deaths from flash floods for five consecutive years.However,under the influence of global climate change,disaster-inducing heavy rainfall events occurred frequently in Guangxi in 2025 which resulted in multiple flash flood disasters.Among them,the flash floods and debris flows in Longsheng County resulted in 8 deaths,and a flash flood-related production safety accident in Longlin County caused 4 deaths,exposing weaknesses in the flash flood disaster prevention system in some areas.This paper analyzes the characteristics of flash flood disasters in Guangxi in 2025 and the shortcomings in defense,proposes countermeasures and suggestions,and provides reference for flash flood prevention and control.关键词
