%X 本文利用数理统计方法，分析了2020年富水流域梅雨期一次典型暴雨洪水过程的暴雨成因、暴雨洪水特征、洪水组成、还原计算、重现期、历史洪水比较等，厘清了各干支流洪水遭遇情况，探讨了典型暴雨洪水成因规律。根据流域水库实际调洪情况和区间洪水遭遇分析，还原计算了富水下游阳新水文站天然洪峰流量过程，并与实际发生的洪峰流量过程进行比较，结果表明，通过富水流域大中型水库的调洪作用，极大地减轻了流域的干支流洪水遭遇给下游形成的防洪压力。提出了每年汛期要严控流域的水库湖泊蓄水，尽可能降低下游河道水位，从而达到降低富水流域防洪风险的建议。<br />
The rainstorm causes, rainstorm flood characteristics, flood regional composition, flow restoration calculation, return period and historical flood comparison of a typical rainstorm flood process of Fushui river basin during the 2020 Meiyu period were analyzed. According to the analysis of flood regulation of reservoirs and interval flood encounter, the natural flood peak process of Yangxin station downstream was restored and compared with the actual flood peak process. The results show that through the flood regulation of large and medium-sized reservoirs, the flood control pressure on the downstream caused by the flood encounter is greatly reduced. It is suggested that the water storage of reservoirs and lakes should be strictly controlled in the flood season, and the water level of downstream rivers should be reduced as much as possible, to reduce the flood control risk of Fushui river basin.
