摘　　要：邯郸位于太行山东麓,特殊的地形叠加气候变化导致近年来洪涝灾害频发。研究了1956年以来邯郸市降水量的时空变化趋势,对历史排位前十的年降水暴雨中心进行了梳理,并对2016、2021年场次暴雨降水强度和时空分布进行了分析。研究表明,历史排位前十中50%年份,尤其是2000年以后,暴雨中心出现在西南部浅山区,2016与2021年3场降水的暴雨中心主要集中在西南部浅山区漳河流域及西北部山区洺河上游流域,产汇流时间短,造成山洪暴涨。Handan is located at the eastern foot of the Taihang Mountains,which special terrain and climate changing led frequent flood disasters in recent years.In this paper,the spatial-temporal variation trend of precipitation in Handan City since 1956 were studied,and the precipitation intensity and spatio-temporal distribution of rainstorm in 2016 and 2021 were analyzed.Studies had shown that 50% of the top 10 years in history,especially after 2000,the center of rainstorm occurred in the shallow mountainous of the southwest,and the rainstorm centers of 2016 and 2021 were mainly concentrated in the Zhanghe River basin in the shallow mountainous area of the southwest and the upper reaches of the Minghe River of the northern mountainous area,which converging time is short and caused flash floods.
