通过分析六安市近30年的历史气象资料和社会调查，结果表明：皖西大别山区的极端降水事件主要由梅雨型暴雨和台风型暴雨造成；暴雨洪涝的致灾因素可分为自然因素和社会因素两类，自然因素主要是极端降水过程和特殊地形的影响，社会成因主要包括承灾体脆弱、预警防御机制不健全和科普宣传不到位等，并针对不同的致灾因素提出相应的措施建议。 Based on the analysis of historical meteorological data and social survey in the last 30 years in Lu’an City, the results show that extreme precipitation events in Dabie Mountain area are mainly caused by Meiyu-type rainstorm and Typhoon-type rainstorm; the disaster-causing factors of rainstorm and flood can be divided into natural factors and social factors: the natural factors are mainly the impact of extreme precipitation processes and special topography; the social causes include the vulnerability of hazard-affected bodies, unsound early warning and defense mecha-nisms and the lack of dissemination for popular science knowledge and so on, and measures or suggestions are proposed for the different factors of the disaster.
