摘　　要：基于2016—2019年大别山南坡山区范围内地面气象站逐日降水数据,及地理、地貌和人文资料,研究大别山南坡山区暴雨灾害气象因子的空间分布特征与规律,讨论因子各级别区域的分布情况和大别山南坡山区受各因子影响概况。利用SPSS21.0工具,分析地形、地貌条件,对暴雨灾害危险性进行分析与评价;并结合AHP层次分析法、信息量法、GIS自然断点分级法对大别山南坡山区范围内地质灾害这种典型的山地气象衍生灾害开展风险区划研究。结果表明,蕲春东部、麻城和罗田交界区域暴雨发生危险性最高,危险性等级为严重及以上的区域主要位于麻城、蕲春的县域东部和黄梅的大部分地区。衍生地质灾害风险性为特重的区域较小,只有327.86 km2,仅占总面积的2.75%,主要位于红安北部山区、麻城东南部、黄梅中部等区域,罗田、英山区域内也有小范围的斑块状分布,包括薄刀锋景区和天堂寨景区。Based on the daily precipitation data of surface meteorological stations in the southern slope of the Dabie Mountains from 2016 to 2019,as well as geographical,geomorphological and cul-tural data,this paper studied the spatial distribution characteristics and laws of meteorological factors for rainstorm disasters in the southern slope of the Dabie Mountains,and discussed the distribution of regions at various levels of factors and the general situation of the impact of various factors on the southern slope of the Dabie Mountains.Use SPSS21.0 tool to analyze terrain and geomorphic condi-tions,and analyze and evaluate the risk of rainstorm disasters.Combined with AHP analytic hierar-chy process,information quantity method and GIS natural breakpoint classification method,the risk zoning of geological disasters in the southern slope of Dabie Mountains,a typical mountain meteoro-logical derivative disaster was studied.The results show that the risk of rainstorm in the eastern part of Qichun,Macheng and Luotian areas is the highest.The areas with serious risk level and above are mainly located in the east of Macheng and Qichun counties and most areas of Huangmei.The ar-ea with the highest risk of derivative geological disasters is relatively small,only 327.86 km2,ac-counting for 2.75%of the total area.It is mainly located in the northern mountain area of Hong’an,the southeast of Macheng,the middle of Huangmei and other areas.There are also small patches in Luotian and Yingshan areas,including the thin blade scenic area and Tiantangzhai scenic area.
