摘要
[目的]研究安徽省2015年6月23~30日暴雨洪涝灾害的特征及影响。[方法]采用空间定位、距平百分率、历史对比、极大值推算、灾害影响分析等多种方法对2015年6月23~30日安徽省出现的一次大范围的强降水过程进行综合评估。[结果]此次过程的强降水区主要位于安徽省北部、沿淮及江淮东部地区等地;最强降水过程出现在24~30日,全省每天都有100个以上乡镇超过50 mm,其中27日686个乡镇出现暴雨,范围之广为历史6月第5位;受持续强降水过程影响,滁河流域发生洪涝灾害,合肥、金寨等地发生内涝和山洪地质灾害,江北大部出现气象雨涝,沿淮及江淮东部达重到特涝,灾害造成的损失十分严重;暴雨对农业、交通、江河湖库水位产生一定影响。[结论]该研究为灾害防御提供重要的科学依据。
[Objective] The research aimed to study the characteristics and influence of rainstorm flood disasters in Anhui Province on June 23 to 30,2015. [Method]Using spatial location,anomaly percentage,historical comparison,the maximum calculation,disaster impact analysis and other methods,a wide range of strong precipitation process in Anhui province on June 23 to 30,2015 was evaluated synthetically. [Result]The strong precipitation area of the process was mainly located in the north of Anhui Province,along Huaihe River and eastern Jianghuai Region. The strongest rainfall process on June 24 to 30,the province had more than 100 villages and towns every day more than 50 mm. On 27 th,686 villages and towns had heavy rains,widely scope was the fifth in the history on June. Influenced by continuous heavy rainfall process,Chuhe River occurs floods,the geological disasters occurs in Hefei and Jinzhai,in most parts of Jiangbei occurs the weather rain waterlogging,along Huaihe River and eastern Jianghuai Region was heavy to waterlogging,the disasters losses was very serious. Heavy rains had the impact on agriculture,transportation and river lake water level. [Conclusion] The study provides the important scientific basis for disaster prevention.
